[PATCH AUTOSEL 5.15 01/12] ASoC: fsl_micfil: explicitly clear software reset bit
From: Shengjiu Wang shengjiu.wang@nxp.com
[ Upstream commit 292709b9cf3ba470af94b62c9bb60284cc581b79 ]
SRES is self-cleared bit, but REG_MICFIL_CTRL1 is defined as non volatile register, it still remain in regmap cache after set, then every update of REG_MICFIL_CTRL1, software reset happens. to avoid this, clear it explicitly.

There may be failure when start 1 channel recording after 8 channels recording. The reason is that the CHnF flags are not cleared successfully by software reset.
This issue is triggerred by the change of clearing software reset bit.
CHnF flags are write 1 clear bits. Clear them by force write.

The bounds checks in snd_soc_put_volsw_sx() are only being applied to the first channel, meaning it is possible to write out of bounds values to the second channel in stereo controls. Add appropriate checks.

The table in the datasheet actually shows the volume values in the wrong order, with the two -3dB values being reversed. This appears to have caused the lower of the two values to be used in the driver when the higher should have been, correct this mixup.
