[PATCH 00/12] ASoC: cs42l42: Series of bugfixes and improvements
From: Richard Fitzgerald
Date: Tue Aug 10 2021 - 11:38:46 EST
Various bugfixes and improvements to the cs42l42 codec driver.
Clocking bugfixes:
- Remove any use of MCLK > 12.288 MHz because it isn't possible to switch
between the low and high frequency ranges on-the-fly
- Prevent the PLL configuration being written while the PLL is running
- Correctly set the MCLK for the sample rate converters
ASP bugfixes:
- Ensure the TX (capture) ASP is properly configured when recording
mono audio.
Other bugfixes:
- Prevent NULL pointer deref if there is an interrupt before soc
component probe
Code cleanup:
- Remove the unused runtime suspend/resume functions.
- Remove some code made redundant by an earlier patch
Improvement:
- Add ALSA control for HP path attenuation. Previously this was
always set to -6dB with no way for the user to configure it.
- Add ALSA control to disable the soft volume ramp at the start of
audio.
