From c26d6cdade6c2a96049f24fac64a8e3734188703 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Wed, 28 Jan 2026 11:46:06 -0600 Subject: [PATCH] ASoC: dt-bindings: aw87390: Add Anbernic RG-DS Amplifier 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.
