[alsa-devel] [PATCH 0/2] ASoC: cs42l52: HP gain enum and PCM Mixer dB scale fixes.

[Nicolas Schichan]

Hi,

The two patches in the serie contains the following fixes:

- Use the correct shift value in hp_gain_enum, effectively allowing
  the higher gain values to be effective and the correct gain value to
  be reported to userland wrt what is written to the register.

- Fix the PCM Mixer dB scale so that userland can report the correct
  dB gain values. Note that in its current form, the PCM Mixer control
  will only allow the range [-0.5 dB (0x7f), +12 dB (0x18)] to be
  programmed to the hardware. I don't know if it is intentional or
  not.

Regards,

  ASoC: cs42l52: use correct PCM mixer TLV dB scale to match datasheet.
