From 6779e78e784df8dfac7ee455cc1a9883d4ae8338 Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Mon, 26 Feb 2018 17:51:14 +0200 Subject: MLK-11502 dts: imx7d-sdb: change ramp up delay for VDD_SD1 regulator Currently the ramp up delay for VDD_SD1 regulator is 1s, the delay is added in the following patch: commit 558c8cde973b9b2abf9a69e3be5a887d38185da3 MLK-11277 dts: imx7d-sdb: add ramp up delay for VDD_SD1 regulator Here we find this delay will also impact the sd1 resume time cost, and 1s is too much for the sd1 resume, so we try to reduce the delay time of this VDD_SD1 regulator, finally 200ms pass our test. This patch change the ramp up delay for VDD_SD1 regulator from 1s to 200ms.
