From a97d67d1c4c331644f26704976f92a5b160c3f77 Mon Sep 17 00:00:00 2001 From: Matt Porter Date: Wed, 12 Mar 2014 09:14:39 -0400 Subject: [PATCH] ARM: dts: bcm28155-ap: leave camldo1 on to fix reboot The BCM28155-AP board has a bootloader that expects the camldo1 regulator to be enabled on entry. Currently, the camldo1 regulator is disabled when no longer in use as is the case during a reboot / warm reset. This causes the early bootloader to hang upon entry. Add regulator-always-on to the camldo1 constraint to fix reboot.
