Subject: [PATCH 0/3] ASoC: codecs: Qualcomm codecs fixes

Hi Mark,

We found few issues during runtime pm testing on this codecs.
These 3 patches for wcd938x, wcd934x and lpass-rx-macro should address them.

Thanks,
srini

Subject: [PATCH 1/3] ASoC: codecs: wcd938x: fix volatile register range

Interrupt Clear registers WCD938X_INTR_CLEAR_0 - WCD938X_INTR_CLEAR_2
are not marked as volatile. This has resulted in a missing interrupt bug
while performing runtime pm. regcache_sync() during runtime pm resume path
will write to Interrupt clear registers with previous values which basically
clears the pending interrupt and actual interrupt handler never sees this
interrupt.

This issue is more visible with headset plug-in plug-out case compared to
headset button.

Fix this by adding the Interrupt clear registers to volatile range

Subject: [PATCH 2/3] ASoC: codecs: wcd934x: return error code correctly from hw_params

Error returned from wcd934x_slim_set_hw_params() are not passed to upper layer,
this could be misleading to the user which can start sending stream leading
to unnecessary errors.

Fix this by properly returning the errors.

For some reason we ended up using snd_soc_component_write_field
for HPHL and snd_soc_component_update_bits for HPHR, so fix this.

Applied to

Thanks!

[1/3] ASoC: codecs: wcd938x: fix volatile register range
commit: ea157c2ba821dab789a544cd9fbe44dc07036ff8
[2/3] ASoC: codecs: wcd934x: return error code correctly from hw_params
commit: 006ea27c4e7037369085755c7b5389effa508c04
[3/3] ASoC: codecs: lpass-rx-macro: fix HPHR setting CLSH mask
commit: cb04d8cd0bb0b82acc34cc73cb33ae77cbfb020d

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
