From 50784e61032d89cbbc46ed73a5fb15f27940b947 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Fri, 16 Sep 2016 18:41:21 +0100 Subject: [PATCH] dts: arm64: db820c: add pmic pins specific dts file This patch adds pmic specific dts which are configured specially for db820c. One of such pin is GPIO_F on the Low Speed expansion which has default output voltage of 2.7v. This patch fixes setup for that pin to have an output voltage of 1.8v to comply with 96boards LS expansion specs.
