From 28980fdf8526bb5e761d77011bb0ca921f3313ff Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 15 Jul 2020 23:19:41 -0700 Subject: soc/amd/picasso: Use read-modify-write for ACP_I2S_PIN_CONFIG This change uses read-modify-write to update ACP_I2S_PIN_CONFIG instead of a write operation since the other bits in the register are reserved.
