From d2c3936ebe88ce3cc188d01be0c684884e396293 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 19 Feb 2014 08:13:48 -0300 Subject: [PATCH] ARM: dts: imx6sl-evk: Keep VGEN1 regulator always enabled On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1P2V domain of the imx6sl SoC, so we need to keep it always powered. According to imx6sl datasheet the GPIO block has three supplies: NVCC33_IO, NVCC18_IO and NVCC_1P2V and it states that: "All digital I/O supplies (NVCC_xxxx) must be powered under normal conditions whether the associated I/O pins are in use or not" This problem has been observed by the fact that a GPIO connected to an LED could not work when the PMIC driver was enabled. Keeping VGEN1 regulator always enabled fixes the problem.
