From c7ac2b7b1e4d85fe13a52e10f6c3164d778eb550 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Fri, 6 Dec 2013 13:51:47 +0100 Subject: [PATCH] ARM: tegra: correct Colibri T20 regulator settings Set the parent of the regulators LDO2 to LDO9 according to the schematic. Set the base voltage to 3.3V, there is only 3.3V on the module itself. Set the Core and CPU voltage to the specified voltages of 1.2V and 1.0V respectivly. LDO6 should deliver 2.85V. The attached peripherals were not in use so far.
