From 2499a04617ec860bf7576d05a422a16e318354bf Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Fri, 5 Apr 2019 14:18:44 +0530 Subject: [PATCH] ARM: dts: dra7: Change pbias voltage to 3.3V As per recent TRM[1], PBIAS cell on dra7 devices supports 3.3v and not 3.0v as documented earlier. Update PBIAS regulator max voltage and the voltage written in the driver to reflect this.
