From 3bc351aa97e5c4b346c7223749d057ce0c372195 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 9 Dec 2022 18:59:46 +0100 Subject: [PATCH] ASoC: dt-bindings: adi,adau7002: Convert to DT schema Convert the Analog Devices ADAU7002 Stereo PDM-to-I2S/TDM Converter bindings to DT schema. During the conversion, add properties already used by DTS (sc7180-trogdor-coachz.dts) and Linux driver: 1. wakeup-delay-ms, 2. sound-dai-cells (via referencing dai-common.yaml).
