Wei Yongjun b23ab27b9a soc: mediatek: Make symbol 'mtk_mutex_driver' static
The sparse tool complains as follows:

drivers/soc/mediatek/mtk-mutex.c:464:24: warning:
 symbol 'mtk_mutex_driver' was not declared. Should it be static?

This symbol is not used outside of mtk-mutex.c, so this
commit marks it static.

Roja Rani Yarubandi 29d96eb261 soc: qcom-geni-se: Cleanup the code to remove proxy votes
This reverts commit 048eb908a1 ("soc: qcom-geni-se: Add interconnect
support to fix earlycon crash")

ICC core and platforms drivers supports sync_state feature, which
ensures that the default ICC BW votes from the bootloader is not
removed until all it's consumers are probes.

The proxy votes were needed in case other QUP child drivers
I2C, SPI probes before UART, they can turn off the QUP-CORE clock
which is shared resources for all QUP driver, this causes unclocked
access to HW from earlycon.

Given above support from ICC there is no longer need to maintain
proxy votes on QUP-CORE ICC node from QUP wrapper driver for early
console usecase, the default votes won't be removed until real
console is probed.

Dmitry Osipenko c45e66a6b9 soc/tegra: pmc: Fix completion of power-gate toggling
The SW-initiated power gate toggling is dropped by PMC if there is
contention with a HW-initiated toggling, i.e. when one of CPU cores is
gated by cpuidle driver. Software should retry the toggling after 10
microseconds on Tegra20/30 SoCs, hence add the retrying. On Tegra114+ the
toggling method was changed in hardware, the TOGGLE_START bit indicates
whether PMC is busy or could accept the command to toggle, hence handle
that bit properly.

The problem pops up after enabling dynamic power gating of 3D hardware,
where 3D power domain fails to turn on/off "randomly".

The programming sequence and quirks are documented in TRMs, but PMC
driver obliviously re-used the Tegra20 logic for Tegra30+, which strikes
back now. The 10 microseconds and other timeouts aren't documented in TRM,
they are taken from downstream kernel.

the domain bits to allow retention when idle.

As the TI SoCs have hardware autoidle capabilities, this is safe to do.
The domains will only enter retention on WFI when none of the devices on
the domain block autoidle in the hardware. This follows what we are
already currently doing.

Geert Uytterhoeven 1d9ffbc6b1 soc: renesas: rmobile-sysc: Mark fwnode when PM domain is added
Currently, there are two drivers binding to the R-Mobile System
Controller (SYSC):
  - The rmobile-sysc driver registers PM domains from a core_initcall(),
    and does not use a platform driver,
  - The optional rmobile-reset driver registers a reset handler, and
    does use a platform driver.

As fw_devlink only considers devices, commit bab2d712ee ("PM:
domains: Mark fwnodes when their powerdomain is added/removed") works
only for PM Domain drivers where the DT node is a real device node, and
not for PM Domain drivers using a hierarchical representation inside a
subnode.  Hence if fw_devlink is enabled, probing of on-chip devices
that are part of the SYSC PM domain is deferred until the optional
rmobile-reset driver has been bound.   If the rmobile-reset driver is
not available, this will never happen, and thus lead to complete system
boot failures.

Fix this by explicitly marking the fwnode initialized.

Geert Uytterhoeven 2fb72440b6 soc: renesas: rmobile-sysc: Remove unneeded platform includes
As of commit b587288001 ("ARM: shmobile: R-Mobile: Remove legacy
PM Domain code"), the R-Mobile System Controller driver no longer
handles the adding of platform devices to PM Domains, but delegates that
to the PM Domain core code.

Linus Torvalds 8b83369ddc RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window:
 
 * A check to ensure drivers are properly using uaccess.  This isn't
   manifesting with any of the drivers I'm currently using, but may catch
   errors in new drivers.
 * Some preliminary support for the FU740, along with the HiFive
   Unleashed it will appear on.
 * NUMA support for RISC-V, which involves making the arm64 code generic.
 * Support for kasan on the vmalloc region.
 * A handful of new drivers for the Kendryte K210, along with the DT
   plumbing required to boot on a handful of K210-based boards.
 * Support for allocating ASIDs.
 * Preliminary support for kernels larger than 128MiB.
 * Various other improvements to our KASAN support, including the
   utilization of huge pages when allocating the KASAN regions.
 
 We may have already found a bug with the KASAN_VMALLOC code, but it's
 passing my tests.  There's a fix in the works, but that will probably
 miss the merge window.

clk: Add RISC-V Canaan Kendryte K210 clock driver
Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC.
This new driver with the compatible string "canaan,k210-clk" implements
support for the full clock structure of the K210 SoC. Since it is
required for the correct operation of the SoC, this driver is
selected by default for compilation when the SOC_CANAAN option is
selected.

With this change, the k210-sysctl driver is turned into a simple
platform driver which enables its power bus clock and triggers
populating its child nodes. The sysctl driver retains the SOC early
initialization code, but the implementation now relies on the new
function k210_clk_early_init() provided by the new clk-k210 driver.

The clock structure implemented and many of the coding ideas for the
driver come from the work by Sean Anderson on the K210 support for the
U-Boot project.

Linus Torvalds e767b3530a ARM: SoC drivers for v5.12
Updates for SoC specific drivers include a few subsystems that
 have their own maintainers but send them through the soc tree:
 
 SCMI firmware:
  - add support for a completion interrupt
 
 Reset controllers:
  - new driver for BCM4908
  - new devm_reset_control_get_optional_exclusive_released()

 belong into any other subsystem, most of them living in
 drivers/soc:
 
  - Allwinner/sunxi power management work
  - Allwinner H616 support
 
  - ASpeed AST2600 system identification support

This is mostly 32-bit code for SoC platforms, and looks smaller
 than any such branch I remember from previous kernels, as most
 of this is now handled in other subsystems for modern platforms:
 
 - Minor bugfixes and Kconfig updates for Tegra, Broadcom, i.MX,
   Renesas, and Samsung
 
 - Updates to the MAINTAINERS listing for Actions, OMAP, and Samsung

Linus Torvalds 584ce3c9b4 SoC platform removal
There are a lot of platforms that have not seen any interesting code
 changes in the past five years or more.
 
 I made a list and asked around which ones are no longer in use [1], and
 received confirmation about six ARM platforms and the TI C6x architecture
 that have all reached the end of their life upstream, with no known
 users remaining:
 
  - efm32 -- added in 2011, first Cortex-M, no notable changes after 2013
  - picoxcell -- added in 2011, abandoned after 2012 acquisition
  - prima2 -- added in 20111, no notable changes since 2015
  - tango -- added in 2015, sporadic changes until 2017, but abandoned
  - u300 -- added in 2009, no notable changes since 2013
  - zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes
  - arch/c6x -- added in 2011, but work stalled soon after that
 
 A number of other platforms on the original list turned out to still
 have users. In some cases there are out-of-tree patches and users
 that plan to contribute them in the future, in other cases the code
 is complete and works reliably.

Tony Lindgren effe89e400 soc: ti: omap-prm: Fix occasional abort on reset deassert for dra7 iva
On reset deassert, we must wait a bit after the rstst bit change before
we allow clockdomain autoidle again. Otherwise we get the following oops
sometimes on dra7 with iva:

Unhandled fault: imprecise external abort (0x1406) at 0x00000000
44000000.ocp:L3 Standard Error: MASTER MPU TARGET IVA_CONFIG (Read Link):
At Address: 0x0005A410 : Data Access in User mode during Functional access

(genpd_runtime_resume) from [<c0a33f0c>] (__rpm_callback+0xd8/0x180)

It is unclear what all devices this might affect, but presumably other
devices with the rstst bit too can be affected. So let's just enable the
delay for all the devices with rstst bit for now. Later on we may want to
limit the list to the know affected devices if needed.

Tony Lindgren a249ca66d1 soc: ti: omap-prm: Fix reboot issue with invalid pcie reset map for dra7
Yongqin Liu <yongqin.liu@linaro.org> reported an issue where reboot hangs
on beagleboard-x15. This started happening after commit 7078a5ba7a
("soc: ti: omap-prm: Fix boot time errors for rst_map_012 bits 0 and 1").

We now assert any 012 type resets on init to prevent unconfigured
accelerator MMUs getting enabled on init depending on the bootloader or
kexec configured state.

Turns out that we now also wrongly assert dra7 l3init domain PCIe reset
bits causing a hang during reboot. Let's fix the l3init reset bits to
use a 01 map instead of 012 map. There are only two rstctrl bits and not
three. This is documented in TRM "Table 3-1647. RM_PCIESS_RSTCTRL".

Jae Hyun Yoo 3f94cf1558 soc: aspeed: snoop: Add clock control logic
If LPC SNOOP driver is registered ahead of lpc-ctrl module, LPC
SNOOP block will be enabled without heart beating of LCLK until
lpc-ctrl enables the LCLK. This issue causes improper handling on
host interrupts when the host sends interrupt in that time frame.
Then kernel eventually forcibly disables the interrupt with
dumping stack and printing a 'nobody cared this irq' message out.

To prevent this issue, all LPC sub-nodes should enable LCLK
individually so this patch adds clock control logic into the LPC
SNOOP driver.

The VCU System-Level Control uses an internal PLL to drive the core and
MCU clock for the allegro encoder and decoder based on an external PL
clock.

In order be able to ensure that the clocks are enabled and to get their

register the clocks at the common clock framework. Other drivers are
then able to access the clock via devicetree bindings.

David Gow 1bea2a937d soc: litex: Properly depend on HAS_IOMEM
The LiteX SOC controller driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.

This causes the driver to be enable under make ARCH=um allyesconfig,
even though it won't build.

By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

Geert Uytterhoeven 2dfc564bda soc: renesas: rcar-sysc: Mark device node OF_POPULATED after init
The R-Car System Controller (SYSC) driver registers PM domains from an
early_initcall().  It does not use a platform driver, as secondary CPU
startup on R-Car H1 needs to control the CPU power domains, before
initialization of the driver framework.

As fw_devlink only considers devices, it does not know that the System
Controller is ready.  Hence probing of on-chip devices that are part of
the SYSC PM domain fails if fw_devlink is enabled:

    probe deferral - supplier e6180000.system-controller not ready

Fix this by setting the OF_POPULATED flag for the SYSC device node after
successful initialization.  This will make of_link_to_phandle() ignore
the SYSC device node as a dependency, and consumer devices will be
probed again.

Linus Torvalds 7485e08eec ARM: SoC fixes for v5.11, part 2
These are the current arm-soc bug fixes for linux-5.11. I already merged
 a larger set that just came in during the past three days but has not
 had much exposure in linux-next, so these are the ones I merged last week.
 
 Most of these are for the NXP i.MX platform (descriptions from their
 pull request):
 
  - Fix pcf2127 reset for imx7d-flex-concentrator board.
  - Fix i.MX6 suspend with Thumb-2 kernel.
  - Fix ethernet-phy address issue on imx6qdl-sr-som board.
  - Fix GPIO3 `gpio-ranges` on i.MX8MP.
  - Select SOC_BUS for IMX_SCU driver to fix build issue.
  - Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
    #pwm-cells conversion.
  - Fix duplicated bus node name for i.MX8MN SoC.
  - Fix reset register offset on LS1028A SoC.
  - Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
    index consistent with previous kernel version.
  - Selecting ARM_GIC_V3 on non-CP15 processors to fix one build failure
    with i.MX8M SoC driver.
  - Fix typos with status property on imx6qdl-kontron-samx6i board.
  - Fix duplicated regulator-name on imx6qdl-gw52xx board.
 
 Aside from i.MX, the bugfixes are all over the place:
 
  - Coccinelle found a refcount imbalance on integrator
  - defconfig fix for TI K3
  - A boot regression fix for ST ux500
  - A code preemption fix for the optee driver
  - USB DMA regression on Broadcom Stingray
  - A bogus boot time warning fix for at91 code

Arnd Bergmann 2a3e487a3e Fixes for omaps for v5.11-rc cycle
The recent changes to switch SoCs to boot with ti-sysc interconnect
 target module driver and genpd caused few regressions:
 
 - The omap_prm reset driver needs to clear any reset bits deasserted by
   the bootloader or kexec boot for the three reset bit cases. Otherwise
   we can have an oops with accelerators starting to boot with potentially
   unconfigured MMU for example
 
 - Custom kernel configs are not automatically selecting simple-pm-bus
   driver that we now need to probe interconnects so we need to select it
   always
 
 - We are not passing legacy platform data in auxdata with simple-pm-bus
   like we do for simple-bus. We need to pass auxdata to simple-pm-bus so
   it can pass it to of_platform_populate()
 
 Then recent RCU changes started causing splats for cpuidle44xx that now
 need RCU_NONIDLE added to the calls in several places
 
 And then we have few device specific fixes:
 
 - We need to remove legacy spi-cs-hig for gta04 display to work, and
   set the gpio to active low
 
 - Omap1 specific ohci-omap needs to call gpio_free()
 
 - Droid4 needs to use padconf interrupt for the slider as the edge
   gpio interrupts may be lost for deeper idle states
