Subject: [PATCH v1 0/6] VAG power control improvement for sgtl5000 codec
Date: Tue, 21 May 2019 13:36:13 +0300	[thread overview]
Message-ID: <20190521103619.4707-1-oleksandr.suvorov@toradex.com> (raw)

VAG power control is improved to fit the manual. This fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot
w/o playing any sound, the VAG power remains off that leads to poor
sound quality from line-in.

I.e. after boot:
- Connect sound source to Line-In jack;
- Connect headphone to HP jack;
- Run following commands:
$ amixer set 'Headphone' 80%
$ amixer set 'Headphone Mux' LINE_IN

Also this series includes fixes of non-important bugs in sgtl5000 codec
driver.

Oleksandr Suvorov (6):
  ASoC: sgtl5000: Fix definition of VAG Ramp Control
  ASoC: sgtl5000: add ADC mute control
  ASoC: sgtl5000: Fix of unmute outputs on probe
  ASoC: sgtl5000: Fix charge pump source assignment
  ASoC: Define a set of DAPM pre/post-up events
  ASoC: sgtl5000: Improve VAG power and mute control
