Subject: [PATCH 1/3] ASoC: cs42l42: Correct definition of ADC Volume control
Date: Thu, 29 Jul 2021 18:09:27 +0100 [thread overview]
Message-ID: <20210729170929.6589-1-rf@opensource.cirrus.com> (raw)
The ADC volume is a signed 8-bit number with range -97 to +12,
with -97 being mute. Use a SOC_SINGLE_S8_TLV() to define this
and fix the DECLARE_TLV_DB_SCALE() to have the correct start and
mute flag.
Fixes: 2c394ca79604 ("ASoC: Add support for CS42L42 codec")
