From 8008b6f3ac155ff9351841ac00253cd41119d1d8 Mon Sep 17 00:00:00 2001 From: "Derald D. Woods" Date: Tue, 3 Jul 2018 20:48:30 -0500 Subject: [PATCH] ARM: dts: am3517-evm: Add 'vdd_io_reg' regulator references There are a few peripherals that generate some extra noise when they don't have a regulator assigned to them. This patch assigns them to their actual tps65023 regulator 'vdd_io_reg' (VDCDC2). Signed-off-by: Derald D.
