From 6a4b6b062a5917d611c1bde7189c5147cf0ca832 Mon Sep 17 00:00:00 2001 From: Bastien Curutchet Date: Tue, 2 Apr 2024 09:12:02 +0200 Subject: [PATCH] ASoC: dt-bindings: davinci-mcbsp: Add optional clock The McBSP uses an internal sample rate generator to provide bit clock or frame clock. This sample rate generator can be programmed to be driven by McBSP's internal clock source or by an external clock source (located on CLKS pin). The external clock source is not described in the bindings. Add an optional clock item that allows to select an external clock as sample rate generator's input.
