From d9105423a8c0f1e6a66ceaa78efcf6a2bb8b7431 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Thu, 13 May 2021 12:41:28 +0200 Subject: [PATCH] ASoC: dt-bindings: codecs: Add bindings for nxp, tfa989x NXP/Goodix TFA989X (TFA1) amplifiers are controlled via an I2C bus. Add simple device tree bindings that describe how to set them up in the device tree. Right now only nxp,tfa9895 is supported but this will be extended to at least nxp,tfa9897 in the near future.
