From a950edcdb7a52362287783386dc5f6404d1a9dd8 Mon Sep 17 00:00:00 2001 From: Clark Wang Date: Fri, 30 Oct 2020 12:34:50 +0800 Subject: [PATCH] MLK-24941 arm: dts: set sensor regulator always on for imx6q/qp/dl This is a workaround. Always open the regulator of the sensor to ensure that the pull-up of i2c3 is 3.3v. Otherwise, there will be a 1.8v high level pull-up before enable sensor regulator in kernel boot stage.
