From 54cd97cfe02e9bb93db53e7cbfa9b672bf4a5ac8 Mon Sep 17 00:00:00 2001 From: Sugar Zhang Date: Thu, 4 Apr 2019 11:57:57 +0800 Subject: ASoC: rockchip: pdm: Correct PDM_CTRL0 reg value This patch fix the wrong reg value for rk322x/rk322xh, cuz there is no STORE JUSTIFIED MODE on it. on rk322x/rk322xh, the same bit means PDM_MODE/RESERVED, if the bit is set to RESERVED, the controller will not work.
