From 4051c4f5c6b04fa2b4dc60eca9deeb6242111258 Mon Sep 17 00:00:00 2001 From: Joerg Schambacher Date: Fri, 29 Sep 2023 17:05:55 +0200 Subject: [PATCH 0754/1085] ASoC: pcm512x: Adds bindings for TAS575x devices commit 736b884a7b68c4eeb66dbf75b97c8ec9b9eeff7f upstream. The TAS5754/6 power amplifiers use the same pcm512x driver with only minor restictions described in the bindings document.
