ALSA: cs35l41: Fix for old systems which do not support command

2023-11-20T11:37:01+00:00

Some older laptops using cs35l41 use firmware which does not support
the CSPL_MBOX_CMD_SPK_OUT_ENABLE command.
Firmware versions v0.28.0 and older do not support this command.

Merge tag 'asoc-v6.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v6.7

More updates for v6,7 following the early merge request:

  - Fixes for handling of component name prefixing when name prefixes
    are used by the machine driver.
  - Fixes for noise when stopping some Sounwire CODECs.
  - Support for AMD ACP 6.3 and 7.0, Awinc AW88399, more Intel
    platforms and more Qualcomm SC7180 platforms.

ASoC: Merge up workaround for CODECs that play noise on stopped stream

2023-10-27T21:33:15+00:00

This was sent too late to actually make it for v6.6 but was sent against
v6.6 so merge it up here.

ASoC: soc-dai: add flag to mute and unmute stream during trigger

2023-10-27T16:44:04+00:00

In some setups like Speaker amps which are very sensitive, ex: keeping them
unmute without actual data stream for very short duration results in a
static charge and results in pop and clicks. To minimize this, provide a way
to mute and unmute such codecs during trigger callbacks.

ASoC: cs35l41: Detect CSPL errors when sending CSPL commands

2023-10-26T15:55:29+00:00

The existing code checks for the correct state transition after sending
a command. However, it is possible for the message box to return -1,
which indicates an error, if an error has occurred in the firmware.
We can detect if the error has occurred, and return a different error.
In addition, there is no recovering from a CSPL error, so the retry
mechanism is not needed in this case, and we can return immediately.

ALSA: hda: cs35l41: Force a software reset after hardware reset

2023-10-26T15:55:20+00:00

To ensure the chip has correctly reset during probe and system suspend,
we need to force a software reset, in case of systems where the
hardware reset is not available.

The software reset register was labelled as volatile but not readable,
however, it is readable, (just returns 0x0). Adding it to readable
registers means it will be correctly treated as volatile, and thus
will not be cached.

ASoC: simple-card-utils: Make simple_util_remove() return void

2023-10-23T12:29:45+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.

simple_util_remove() returned zero unconditionally. Make it return void
instead and convert all users to struct platform_device::remove_new().
