From 4a5057d8fa0cf5651e896f4386c031e2671e78b5 Mon Sep 17 00:00:00 2001 From: Yu-Ping Wu Date: Wed, 28 Apr 2021 13:59:18 +0800 Subject: mb/google/asurada: Fix power on delay From ANX7625 spec, the delay between powering on power supplies and GPIO should be larger than 10ms. Since it takes about 4ms for the previous GPIO EN_PP3300_EDP_DX to be pulled up, increase the delay from 2ms to 14ms.
