From ca9d237994db63dca68f2b04e257a4738847deee Mon Sep 17 00:00:00 2001 From: Venkata Prasad Potturu Date: Mon, 9 Jan 2023 18:51:02 +0530 Subject: [PATCH] ASoC: amd: acp: Refactor i2s clocks programming sequence Refactor i2s clock values based on hw_params and use srate and bclk_ratio variables in clock enable API instead hard-code values.
