From aa897ffc396b48cc39eee133b6b43175d0df9eb5 Mon Sep 17 00:00:00 2001 From: Ranganath V N Date: Tue, 4 Nov 2025 16:04:58 +0530 Subject: [PATCH] ASoC: dt-bindings: ti,pcm1862: convert to dtschema convert the Texas Instruments PCM186x Universal audio ADC bindings to DT schema. The PCM186x codec provides a single digital audio interface. Therefore this binding adds a reference to dai-common.yaml and defines '#sound-dai-cells = 0".
