Subject: twl-regulator: Define critical regulators as always_on
X-Git-Tag: v3.0~6460^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=205e5cd3d933a9ea7b75630355c8f8ec5ef16f6c;p=platform%2Fkernel%2Flinux-amlogic.git

twl-regulator: Define critical regulators as always_on

Defines VIO, VDD1, VDD2, VPLL1 and VINT* regulators as always_on by default
since they are critical to TWL and its master's functionality and should
be on in all cases where RegFW is used
