Subject: [PATCH 4.14 61/61] ASoC: sgtl5000: Improve VAG power and mute control
Date: Thu, 10 Oct 2019 10:37:26 +0200 [thread overview]
Message-ID: <20191010083528.179896623@linuxfoundation.org> (raw)
In-Reply-To: <20191010083449.500442342@linuxfoundation.org>
From: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>
[ Upstream commit b1f373a11d25fc9a5f7679c9b85799fe09b0dc4a ]
VAG power control is improved to fit the manual [1]. This patch fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot,
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
Change VAG power on/off control according to the following algorithm:
- turn VAG power ON on the 1st incoming event.
- keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In).
- turn VAG power OFF when there is the latest consumer's pre-down event
come.
- always delay after VAG power OFF to avoid pop.
- delay after VAG power ON if the initiative consumer is Line-In, this
prevents pop during line-in muxing.
According to the data sheet [1], to avoid any pops/clicks,
the outputs should be muted during input/output
routing changes.
