Subject: ASoC: dt-bindings: document dvdd-supply property for awinic,aw88261
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=18d524de812ff37e7de12a2acddfe7eee6b4ca3c;p=thirdparty%2Fkernel%2Flinux.git

ASoC: dt-bindings: document dvdd-supply property for awinic,aw88261

Add (and require) the dvdd-supply property for awinic,aw88261 in
the awinic,aw88395.yaml binding.

The chip needs DVDD to power on, and currently there are no users of
this compatible in the kernel device trees, so we should be fine to
change the ABI in this case.
