From 1d1a15d87f200bc08a610c5243631b270e8b4e47 Mon Sep 17 00:00:00 2001 From: Jimmy Zhang Date: Thu, 20 Nov 2014 15:43:04 -0800 Subject: [PATCH] google/rush_ryu: Remove long delay when turning on AVDD_DSI_CSI Based on TPS65913, the max LDO turn on time is 500us. Since it is requested the default delay of 500us when calling function pmic_write_reg(), it is safe to remove this 100ms delay.
