Pierre-Louis Bossart 3b0b441a29 soundwire: intel_ace2x: use DOAIS and DODS settings from firmware

Pierre-Louis Bossart a36ec5f762 soundwire: intel_ace2x: simplify check_wake()
Since LunarLake, we use the HDadio WAKEEN/WAKESTS to detect wakes for
SoundWire codecs. This patch follows the HDaudio example and
simplifies the behavior on wake-up by unconditionally waking up all
links.

This behavior makes a lot of sense when removing the jack, which may
signal that the user wants to start rendering audio using the local
amplifiers. Resuming all links helps make sure the amplifiers are
ready to be used. Worst case, the pm_runtime suspend would kick-in
after several seconds of inactivity.

Pierre-Louis Bossart 79e7123c07 soundwire: intel_ace2x: fix wakeup handling
The initial programming sequence only worked in the case where the
OFLEN bit is set, i.e. the DSP handles the SoundWire interface. In the
Linux integration, the interface is owned by the host. This disconnect
leads to wake-ups being routed to the DSP and not to the host.

The suggested update is to rely on the global HDAudio WAKEEN/STATESTS
registers, with the SDI bits used to program the wakeups and check the
status.

Note that there is no way to know which peripheral generated a
wake-up. When the hardware detects a change, it sets all the bits
corresponding to LSDIIDx. The LSDIIDx information can be used to
figure out on which link the wakeup happened, but for further details
the software will have to check the status of each peripheral.

Bard Liao 4cd5ea6de1 soundwire: intel_init: resume all devices on exit.
When the manager becomes pm_runtime active in the remove procedure,
peripherals will become attached, and do the initialization
process. We have to wait until all the devices are fully resumed
before the cleanup, otherwise there is a possible race condition where
asynchronous workqueues initiate transfers on the bus that cannot
complete. This will ensure there are no SoundWire registers accessed
after the bus is powered-down.

Pierre-Louis Bossart b18c25afab soundwire: intel_ace2x: use legacy formula for intel_alh_id
Starting with Lunar Lake, the notion of ALH is mostly irrelevant,
since the HDaudio DMAs are used. However the firmware still relies on
an 'ALH gateway' with a 'node_id' based on the same formula.

This patch in isolation has no functional impact, it's only when the
ASoC parts use it that we will see a changed behavior.

Pierre-Louis Bossart 8ee1b439b1 soundwire: cadence: fix invalid PDI offset
For some reason, we add an offset to the PDI, presumably to skip the
PDI0 and PDI1 which are reserved for BPT.

This code is however completely wrong and leads to an out-of-bounds
access. We were just lucky so far since we used only a couple of PDIs
and remained within the PDI array bounds.

A Fixes: tag is not provided since there are no known platforms where
the out-of-bounds would be accessed, and the initial code had problems
as well.

Uwe Kleine-König fe12bec586 soundwire: qcom: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Greg Kroah-Hartman fc7e56017b soundwire: sysfs: have the driver core handle the creation of the device groups
The driver core supports the ability to handle the creation and removal
of device-specific sysfs files in a race-free manner.  Take advantage of
that by converting this driver to use this by moving the sysfs
attributes into a group and assigning the dev_groups pointer to it.

Greg Kroah-Hartman 3ee43f7cc9 soundwire: sysfs: cleanup the logic for creating the dp0 sysfs attributes
There's no need to special-case the dp0 sysfs attributes, the
is_visible() callback in the attribute group can handle that for us, so
add that and add it to the attribute group list making the logic simpler
overall.

This is a step on the way to moving all of the sysfs attribute handling
into the default driver core attribute group logic so that the soundwire
core does not have to do any of it manually.

Greg Kroah-Hartman b1b11bb078 soundwire: sysfs: move sdw_slave_dev_attr_group into the existing list of groups
The sysfs logic already creates a list of groups for the device, so add
the sdw_slave_dev_attr_group group to that list instead of having to do
a two-step process of adding a group list and then an individual group.

This is a step on the way to moving all of the sysfs attribute handling

Krzysztof Kozlowski 15c7fab0e0
ASoC: qcom: Move Soundwire runtime stream alloc to soundcards
Currently the Qualcomm Soundwire controller in its DAI startup op
allocates the Soundwire stream runtime.  This works fine for existing
designs, but has limitations for stream runtimes with multiple
controllers, like upcoming Qualcomm X1E80100 SoC with four WSA8840
speakers on two Soundwire controllers.

When two Soundwire controllers are added to sound card codecs, Soundwire
startup() is called twice, one for each Soundwire controller, and second
execution overwrites what was set before.  During shutdown() this causes
double free.

It is expected to have only one Soundwire stream runtime, thus it should
be allocated from SoC soundcard context startup(), not from each
Soundwire startup().  Such way will properly handle both cases: one and
two Soundwire controllers in the stream runtime.

The current code fills DOAIS, DACTQE and DODS bits to a
variable initialized to zero, and updates the variable
to AC timing control register. With this operation, We
change DOAISE to 0, and force a much more aggressive
timing. The timing is even unable to form a working
waveform on SDA pin.

This patch uses read-modify-write operation for the AC
timing control register access, thus makes sure those
bits not supposed and intended to change are not touched.

Krzysztof Kozlowski e199bf52ff soundwire: stream: fix NULL pointer dereference for multi_link
If bus is marked as multi_link, but number of masters in the stream is
not higher than bus->hw_sync_min_links (bus->multi_link && m_rt_count >=
bus->hw_sync_min_links), bank switching should not happen.  The first
part of do_bank_switch() code properly takes these conditions into
account, but second part (sdw_ml_sync_bank_switch()) relies purely on
bus->multi_link property.  This is not balanced and leads to NULL
pointer dereference:

  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
  ...

Srinivas Kandagatla a7ae05ef35 soundwire: qcom: set controller id to hw master id
Qualcomm Soundwire Controllers IP version after 1.3 have a dedicated
master id register which will provide a unique id value for each
controller instance. Use this value instead of artificially generated
value from idr. Versions 1.3 and below only have one instance of
soundwire controller which does no have this register, so let them use
value from idr.

Krzysztof Kozlowski 8a8a9ac8a4 soundwire: fix initializing sysfs for same devices on different buses
If same devices with same device IDs are present on different soundwire
buses, the probe fails due to conflicting device names and sysfs
entries:

  sysfs: cannot create duplicate filename '/bus/soundwire/devices/sdw:0:0217:0204:00:0'

The link ID is 0 for both devices, so they should be differentiated by
the controller ID. Add the controller ID so, the device names and sysfs entries look
like:

  sdw:1:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6ab0000.soundwire-controller/sdw-master-1-0/sdw:1:0:0217:0204:00:0
  sdw:3:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6b10000.soundwire-controller/sdw-master-3-0/sdw:3:0:0217:0204:00:0

[PLB changes: use bus->controller_id instead of bus->id]
