From 86ddd8ad2fc34c7c302251a5e95c7afe1bfc80c3 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Wed, 29 May 2019 14:50:56 +0800 Subject: ARM: dts: imx7d-sdb: Make SW2's voltage fixed On i.MX7D SDB board, SW2 supplies a lot of peripheral devices, its voltage should be fixed at 1.8V. The commit 43967d9b5a7c ("ARM: dts: imx7d-sdb: Assign corresponding power supply for LDOs") assigns SW2 as the supplier of vdd1p0d, and when its comsumers pcie-phy/mipi-phy try to set the vdd1p0d to 1.0V, regulator core will also set SW2 to its best(min) voltage to 1.5V, and it will lead to board reset. This patch makes SW2's voltage fixed at 1.8V to avoid this issue.
