Ezequiel Garcia 832e6609f7 media: pxa_camera: Drop the v4l2-clk clock register
Now that mach-based PXA platforms are registering proper
fixed-rate clocks through the CCF, the v4l2-clk clock
is no longer required.

Drop this clock, so the driver no longer depends on the
legacy v4l2-clk API.

Laurent Pinchart b01edcbd40 media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API
The functions that add an async subdev to an async subdev notifier take
as an argument the size of the container structure they need to
allocate. This is error prone, as passing an invalid size will not be
caught by the compiler. Wrap those functions in macros that take a
container type instead of a size, and cast the returned pointer to the
desired type. The compiler will catch mistakes if the incorrect type is
passed to the macro, as the assignment types won't match.

Ezequiel Garcia be5ec392bb media: davinci: vpif_display: Remove unused v4l2-async code
There are no users for vpif_display_config.asd_sizes
and vpif_display_config.asd members, which means the v4l2-async
subdevices aren't being defined anywhere.

Remove the v4l2-async, leaving only the synchronous setup.

Drivers are instead encouraged to use a helper such as

Change v4l2_async_notifier_add_fwnode_remote_subdev semantics
so it allocates the struct v4l2_async_subdev pointer.

This makes the API consistent: the v4l2-async subdevice addition
functions have now a unified usage model. This model is simpler,
as it makes v4l2-async responsible for the allocation and release
of the subdevice descriptor, and no longer something the driver
has to worry about.

On the user side, the change makes the API simpler for the drivers
to use and less error-prone.

Heiko Stuebner ef357e02b6 media: rockchip: rkisp1: extend uapi array sizes
Later variants of the rkisp1 block use more entries in some arrays:

RKISP1_CIF_ISP_AE_MEAN_MAX                 25 -> 81
RKISP1_CIF_ISP_HIST_BIN_N_MAX              16 -> 32
RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES       17 -> 34
RKISP1_CIF_ISP_HISTOGRAM_WEIGHT_GRIDS_SIZE 25 -> 81

and we can still extend the uapi during the 5.11-rc cycle, so do that
now to be on the safe side.

V10 and V11 only need the smaller sizes, while V12 and V13 needed
the larger sizes.

When adding the bigger sizes make sure, values filled from hardware
values and transmitted to userspace don't leak kernel data by zeroing
them beforehand.

Heiko Stuebner fc672d806b media: rockchip: rkisp1: carry ip version information
The IP block evolved from its rk3288/rk3399 base and the vendor
designates them with a numerical version. rk3399 for example
is designated V10 probably meaning V1.0.

There doesn't seem to be an actual version register we could read that
information from, so allow the match_data to carry that information
for future differentiation.

Also carry that information in the hw_revision field of the media-
controller API, so that userspace also has access to that.

The added versions are:
- V10: at least rk3288 + rk3399
- V11: seemingly unused as of now, but probably appeared in some soc
- V12: at least rk3326 + px30
- V13: at least rk1808

Rename the functions to make it obvious that the function are only valid
for H.264.

param contains the value without the minus4, but since firmware
version 2019.1, the value has to be log2_max_pic_order_cnt_lsb - 1,
presumably to fit the maximum value of 16 into a 4 bit field.

The driver does not support firmware version 2019.1. Thus, change the
behaviour starting from firmware version 2019.2.

Michael Tretter 83a4b7fd7f media: allegro: move encoding options to channel
There are several encoding options that are hard coded in the parameter
that is used to configure the hardware codec. However, some of the
options must be written to the SPS/PPS by the driver. Furthermore, some
of the options depend on the codec that is used (i.e. H.264 or HEVC).

Therefore, move options that depend on the codec to the channel and add
constants for options that are independent of the codec but must be
written to the SPS/PPS.

Currently we rely on firmware to return error when we reach the maximum

To achieve that modify hfi_session_create to return error when we reach

Laurent Pinchart cbb8cd7cc1 media: ti-vpe: cal: Stop write DMA without disabling PPI
When stopping the stream, the driver needs to ensure that ongoing DMA
completes and that no new DMA is started. It does so using a feature of
the PPI that can be stopped on a frame boundary. The downside of this
mechanism is that the DMA can't be stopped independently of the source,
which prevents usage of multiple contexts for the same source (to handle
CSI-2 virtual channels or data types).

Rework the stream stop mechanism to stop the write DMA without disabling
the PPI first. The new mechanism relies on the combination of a state
machine in the driver and shadowing of the CAL_WR_DMA_CTRL_j.MODE field
in the hardware. When a stop is requested, the DMA start interrupt
handler will request the hardware to stop at the end of the current
frame by disabling the write DMA context in the shadowed register, and
flag that a stop is in progress. The next DMA end interrupt will then
report that the stop is complete.

This makes it possible to stop the PPI after stopping the DMA, and fold
the cal_camerarx_ppi_disable() call into cal_camerarx_stop().

starting the CAMERARX, which is desirable anyway.

Laurent Pinchart 75c80311ed media: ti-vpe: cal: Refactor interrupt enable/disable
Interrupts are enabled and disabled by the cal_camerarx_enable_irqs()
and cal_camerarx_disable_irqs(). Despite their name, they deal with all
interrupts, not just the CAMERARX interrupts, and they hardcode the
assumption that the context index is identical to the CAMERARX index.

Split the context-related interrupt management to two new functions,
cal_ctx_enable_irqs() and cal_ctx_disable_irqs(), called from the
cal_start_streaming() and cal_stop_streaming() functions. The explicit
calls to cal_camerarx_enable_irqs() and cal_camerarx_disable_irqs() are
folded with the CAMERARX .s_stream() operation to simplify the CAMERARX
API.

Enabling the OCPO error interrupt is moved to the PM runtime resume
operation, as it's global to the device, not related to a CAMERARX or
context. The VC IRQ enable and disable are removed as they're not used,
the parent interrupt bit (CAL_HL_IRQ_VC_MASK) never being set.

Linus Torvalds 48c1c40ab4 ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
 merge their drivers through the SoC tree, those changes include:
 
  - The SCMI firmware framework gains support for sensor notifications
    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

Jacopo Mondi fb25ca3731 media: rcar-vin: Mask VNCSI_IFMD register
The VNCSI_IFMD register controls the data expansion mode and the
channel routing between the CSI-2 receivers and VIN instances.

According to the chip manual revision 2.20 not all fields are available
for all the SoCs:
- V3M, V3H and E3 do not support the DES1 field has they do not feature
  a CSI20 receiver.
- D3 only supports parallel input, and the whole register shall always
  be written as 0.

Inspect the per-SoC channel routing table where the available CSI-2
instances are reported and configure VNCSI_IFMD accordingly.

This patch supports this BSP change commit:

https://github.com/renesas-rcar/linux-bsp/commit/f54697394457

The driver implements a Memory2Memory VB2 V4L2 streaming device permitting:
- 0, 90, 180, 270deg rotation
- horizontal/vertical flipping
- source cropping
- destination compositing
- 32bit/24bit/16bit format conversion

This adds the support for the GE2D version found in the AXG SoCs Family.

The missing features are:
- Source scaling
- Colorspace conversion
- Advanced alpha blending & blitting options

This reverts commit c90f1178dc.

The assumption of "Each entry in formats[] table has unique mbus_code"
is valid for the RDI entities, but not for the PIX ones.

Reverting this patch and creating a new one which handles the PIX entities
correctly results in smaller and more straightforward patch than doing the

Each iteration of for_each_child_of_node puts the previous node, but in
the case of a goto from the middle of the loop, there is no put, thus
causing a memory leak. Hence add a new label that puts the last used

to the new label.

AngeloGioacchino Del Regno 4863b93cfd media: camss: csiphy: Set rate on csiX_phy clock on SDM630/660
The SDM630/660 SoCs (and variants) have another clock source
for the PHY, which must be set to a rate that's equal or
greater than the CSI PHY timer clock: failing to do this
will produce PHY overflows when trying to get a stream from
a very high bandwidth camera sensor and outputting no frame
or a partial one.

Since I haven't found any usecase in which the csiX_phy
clock needs to be higher than the csiXphy_timer, let's just
set the same rate on both, which seems to work just perfect.

After revisit the OPP part of the code I found that OPP pmdomain
is detached with direct call to dev_pm_domain_detach instead of
OPP wraper for detaching pmdomains with OPP table. Correct this
by calling the OPP dev_pm_opp_detach_genpd.

To avoid potentially overflowing the kernel logs in the case

Ezequiel Garcia 8297ae5c29 media: coda: coda_buffer_meta housekeeping fix
It's possible that the VPU was initialized using just one buffer,
containing only codec headers.

In this case, right after the initialization and after updating
the FIFO read pointer, we need to iterate through all the coda_buffer_meta
and release any metas that have been already used by the VPU.

This issue is affecting indirectly the bitstream buffer fill
threshold, which depends on the meta end position of the first
queued meta, which is passed to coda_bitstream_can_fetch_past().

Without this fix, it's possible that for certain videos, the
bitstream buffer level is not filled properly, resulting in a PIC_RUN
timeout.

Niklas Söderlund bea2b6a4e1 media: rcar-vin: Add support for suspend and resume
Add support for suspend and resume by stopping and starting the video
pipeline while still retaining all buffers given to the driver by
user-space and internally allocated ones, this gives the application a
seamless experience.

Buffers are never returned to user-space unprocessed so user-space don't
notice when suspending. When resuming the driver restarts the capture
session using the internal scratch buffer, this happens before
user-space is unfrozen, this leads to speedy response times once the
application resumes its execution.

As the entire pipeline is stopped on suspend all subdevices in use are
also stopped, and if they enter a shutdown state when not streaming
(such as the R-Car CSI-2 driver) they too will be suspended and resumed
in sync with the VIN driver.

To be able to do keep track of which VINs should be resumed a new
internal state SUSPENDED is added to recode this.

Niklas Söderlund 90ed57851e media: rcar-vin: Use scratch buffer when not in running state
In its early stages the VIN driver did not use an internal scratch
buffer. This leads to a unnecessary complex start and stop behavior,
specially for TB/BT. The driver now always allocates a scratch buffer to
deal with buffer under-runs, use the scratch buffer to also simplify
starting and stopping.

When capture is starting use the scratch buffer instead of a user-space
buffers while syncing the driver with the hardware state. This allows
the driver to know that no user-space buffer is given to the hardware
before the running state is reached.

When capture is stopping use the scratch buffer instead of leaving the
user-space buffers in place and add a check that all user-space buffers
are processed by the hardware before transitioning from the stopping to
stopped state. This allows the driver to know all user-space buffers
given to the hardware are fully processed.

This change in itself does not improve the driver much but it paves the
way for future simplifications and enhancements. One direct improvement
of this change is that TB/BT buffers returned to user-space while stopping
will always contain both fields, that was not guaranteed before.

Alexandre Courbot 2da185d6fe media: mtk-vcodec: fix build breakage when one of VPU or SCP is enabled
The addition of MT8183 support added a dependency on the SCP remoteproc
module. However the initial patch used the "select" Kconfig directive,
which may result in the SCP module to not be compiled if remoteproc was
disabled. In such a case, mtk-vcodec would try to link against
non-existent SCP symbols. "select" was clearly misused here as explained
in kconfig-language.txt.

Replace this by a "depends" directive on at least one of the VPU and
SCP modules, to allow the driver to be compiled as long as one of these
is enabled, and adapt the code to support this new scenario.

Also adapt the Kconfig text to explain the extra requirements for MT8173
and MT8183.

the supported codecs which is already stored in the platform data.

Fix this by referring to the platform data to find out whether a given

regardless of the format, we can then return a copy of a static value if
the format is supported.

This reverts commit 81735ecb62.

The hardware needs data to follow the previous alignment, so this extra
space was not superfluous after all. Besides, this also made
v4l2-compliance's G_FMT and S_FMT tests regress.

Jim Quinlan e0d072782c dma-mapping: introduce DMA range map, supplanting dma_pfn_offset
The new field 'dma_range_map' in struct device is used to facilitate the
use of single or multiple offsets between mapping regions of cpu addrs and
dma addrs.  It subsumes the role of "dev->dma_pfn_offset" which was only
capable of holding a single uniform offset and had no region bounds
checking.

The function of_dma_get_range() has been modified so that it takes a single
argument -- the device node -- and returns a map, NULL, or an error code.
The map is an array that holds the information regarding the DMA regions.
Each range entry contains the address offset, the cpu_start address, the
dma_start address, and the size of the region.

of_dma_configure() is the typical manner to set range offsets but there are
a number of ad hoc assignments to "dev->dma_pfn_offset" in the kernel
driver code.  These cases now invoke the function
dma_direct_set_offset(dev, cpu_addr, dma_addr, size).

Marek Szyprowski 34e8548168 drm: rcar-du: fix common struct sg_table related issues
The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().

struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).

It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.

To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

dma_map_sgtable() function returns zero or an error code, so adjust the
return value check for the vsp1_du_map_sg() function.

Stanimir Varbanov 73d513e45a media: venus: Add new interface queues reinit
Presently the recovery mechanism is using two hfi functions
to destroy and create interface queues. For the purpose of
recovery we don't need to free and allocate the memory used
for interface message queues, that's why we introduce new
function which just reinit the queues.  Also this will give
to the recovery procedure one less reason to fail (if for
some reason we couldn't allocate memory).

Loic Poulain 58084b3f6c media: venus: Fix reported frame intervals
On dragonboard-410c (apq8016) with HFI_VERSION_1XX, the reported
framerate is in unit of 1/65535 fps (for fine grained control).
So the current reported supported frame intervals is wrong (max
is 1/65535 fps), leading to encoding issues or format negotiation
failures with gstreamer.

Fix that by setting the framerate denominator to coherent value
based on the the framerate factor.

The factor is not always the same, e.g. with db820c (apq8096) HFI
reports framerate in fps unit. So only apply that for HFI_VERSION_1XX.

Vikash Garodia e1c69c4eef media: venus: fixes for list corruption
There are few list handling issues while adding and deleting
node in the registered buf list in the driver.
1. list addition - buffer added into the list during buf_init
while not deleted during cleanup.
2. list deletion - In capture streamoff, the list was reinitialized.
As a result, if any node was present in the list, it would
lead to issue while cleaning up that node during buf_cleanup.

Niklas Söderlund f18d6a4cb0 media: rcar-vin: Unconditionally unregister notifier on remove
If the VIN device is part of a group of VIN devices (all Gen3 boards)
there is no reason to only unregister the group notifier if the VIN that
registers the notifier is removed. The VIN that registers the notifier
is always the last VIN device to be bound, so keeping the notifier
around after any VIN is unbound creates an unbalanced state where no VIN
in the group is operational.

Fix this by unconditionally unregistering the notifier when any VIN
device is unbound. Unregistering the notifier will lead to unbound()
being called and all video devices exposed by any VIN instance to be
removed.

The lock was only needed to protect the check which VIN registers the
notifier and is no longer needed.

Lubomir Rintel 953e41153a media: cafe-driver: use drvdata instead of back-casting from v4l2_device
Since commit 95db3a60e0 ("[media] v4l: Add a media_device pointer
to the v4l2_device structure") the v4l core doesn't insist on using drvdata
itself.  Therefore we can use it ourselves, making things somewhat simpler.
