From 025e33ee387a398a51588834c3172bedf4f9c485 Mon Sep 17 00:00:00 2001 From: Marc Dietrich Date: Fri, 9 Dec 2016 10:20:38 +0100 Subject: 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.

Table 8 from MX6DL datasheet (IMX6SDLCEC Rev. 5, 06/2015): http://cache.nxp.com/files/32bit/doc/data_sheet/IMX6SDLCEC.pdf states the following: "LDO Output Set Point (VDD_ARM_CAP) = 1.125 V minimum for operation up to 396 MHz." So fix the entry by adding the 25mV margin value as done in the other entries of the table, which results in 1.15V for 396MHz operation.
