From c0b7202b834384da153dd8fe5d87d27e516b4dce Mon Sep 17 00:00:00 2001 From: Robin Gong Date: Thu, 23 Mar 2017 11:34:40 +0800 Subject: MLK-14510: ARM: dts: imx6ull-14x14-ddr3-arm2: fix pfuze200 probe error SW3B fused to high voltage 0.8v~3.3v and the low voltage setting in dts cause pfuze200 driver probe failed as below even if the pfuze driver have already updated the voltage to the right 0.8v~3.3v.But the issue not caught on v4.1 since it's common regualtor framework behavior. Correct the SW3B into the right voltage in v4.9 fuze100-regulator 0-0008: pfuze200 found.
