From 9f138bb2eaf661788df459dfcaf38feb080af41f Mon Sep 17 00:00:00 2001 From: Sameer Pujar Date: Thu, 9 Feb 2023 20:06:56 +0530 Subject: [PATCH] ASoC: rt5640: Update MCLK rate in set_sysclk() Simple-card/audio-graph-card drivers do not handle MCLK clock when it is specified in the codec device node. The expectation here is that, the codec should actually own up the MCLK clock and do necessary setup in the driver. This is inspired from, commit dbf54a953435 ("ASoC: rt5659: Update MCLK rate in set_sysclk()").
