Subject: [PATCH v6 15/16] ASoC: cs35l41: Document CS35l41 External Boost
Date: Sat, 9 Apr 2022 10:13:14 +0100 [thread overview]
Message-ID: <20220409091315.1663410-16-tanureal@opensource.cirrus.com> (raw)
In-Reply-To: <20220409091315.1663410-1-tanureal@opensource.cirrus.com>
From: David Rhodes <drhodes@opensource.cirrus.com>
Document internal and external boost feature for ASoC CS35L41.
For internal boost the following properties are required:
- cirrus,boost-peak-milliamp
- cirrus,boost-ind-nanohenry
- cirrus,boost-cap-microfarad
For external boost, the GPIO1 must be configured as output,
so the following properties are required:
- cirrus,gpio1-src-select = <1>
- cirrus,gpio1-output-enable
