ASoC: apple: mca: Add "apple,t8103-mca" compatible

2025-09-14T19:51:29+00:00

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,mca" anymore [1]. Use
"apple,t8103-mca" as base compatible as it is the SoC the driver and
bindings were written for.

ASoC: apple: Standardize ASoC menu

2025-06-24T00:01:24+00:00

Current Kconfig menu at [ALSA for SoC audio support] has no rules.
So, some venders are using menu style, some venders are listed each drivers
on top page, etc. It is difficult to find target vender and/or drivers
because it is very random.

Let's standardize ASoC menu

ASoC: apple: mca: Drop default ARCH_APPLE in Kconfig

2025-06-13T11:12:26+00:00

When the first driver for Apple Silicon was upstreamed we accidentally
included `default ARCH_APPLE` in its Kconfig which then spread to almost
every subsequent driver. As soon as ARCH_APPLE is set to y this will
pull in many drivers as built-ins which is not what we want.
Thus, drop `default ARCH_APPLE` from Kconfig.

ASoC: apple: mca: Constrain channels according to TDM mask

2025-05-19T10:59:44+00:00

We don't (and can't) configure the hardware correctly if the number of
channels exceeds the weight of the TDM mask. Report that constraint in
startup of FE.

ASoC: Switch back to struct platform_driver::remove()

2024-09-09T17:26:49+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

ASoC: apple: Use -y instead of -objs in Makefile

2024-05-08T02:39:14+00:00

*-objs suffix is reserved rather for (user-space) host programs while
usually *-y suffix is used for kernel drivers (although *-objs works
for that purpose for now).

Let's correct the old usages of *-objs in Makefiles.

ASoC: apple: mca: Annotate struct mca_data with __counted_by

2023-10-10T21:10:07+00:00

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct mca_data.

ASoC: apple: mca: Convert to platform remove callback returning void

2023-03-20T13:07:18+00:00

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 (mostly) ignored
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.

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