Subject: [PATCH] ARM: dts: Revert enabling of twl configuration for n900
Date: Fri, 25 Jul 2014 04:41:25 -0700 [thread overview]
Message-ID: <20140725114124.GE29045@atomide.com> (raw)
Commit 9188883fd66e9 (ARM: dts: Enable twl4030 off-idle configuration
for selected omaps) allowed n900 to cut off core voltages during
off-idle. This however caused a regression where twl regulator
vaux1 was not getting enabled for the LCD panel as we are not
requesting it for the panel.
Turns out quite a few devices on n900 are using vaux1, and we need
to either stop idling it, or add proper regulator_get calls for all
users. But until we have a proper solution implemented and tested,
let's just disable the twl off-idle configuration for now for n900.
