Subject: [alsa-devel] [PATCH 1/2][RESEND] ASoC: adau1761: Add PGA Slew time control
Date: Thu, 26 Sep 2019 14:50:11 +0300 [thread overview]
Message-ID: <20190926115012.24049-1-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20190709082111.27221-1-alexandru.ardelean@analog.com>
From: Lars-Peter Clausen <lars@metafoo.de>
The PGA Slew Time control allows to configure the rate with which the PGA
gain control ramps up/down to the target setting.
The PGA slew control is done via the ALC Control 0 register. There are 2
bits on that reg, that control PGA slew time, while the other bits control
parts of the ALC (automatic level control) block.
