From 025e33ee387a398a51588834c3172bedf4f9c485 Mon Sep 17 00:00:00 2001 From: Marc Dietrich Date: Fri, 9 Dec 2016 10:20:38 +0100 Subject: [PATCH] ARM: tegra: paz00: Mark panel regulator as enabled on boot commit 0c18927f51f4d390abdcf385bff5f995407ee732 upstream. Current U-Boot enables the display already. Marking the regulator as enabled on boot fixes sporadic panel initialization failures.
