Subject: [PATCH V2 1/3] ASoC: dt-bindings: aw87390: Add Anbernic RG-DS Amplifier
Date: Wed, 28 Jan 2026 11:46:06 -0600	[thread overview]
Message-ID: <20260128174608.1498-2-macroalpha82@gmail.com> (raw)
In-Reply-To: <20260128174608.1498-1-macroalpha82@gmail.com>

From: Chris Morgan <macromorgan@hotmail.com>

Add a binding for the Anbernic RG-DS Amplifier, which is an Awinic
aw87391 audio amplifier. This manufacturer did not provide firmware
so we have to use a list of init commands instead, requiring device
specific functionality rather than generic aw87391 functionality.
