ARM: dts: nexus7: Add regulator tweaks and wcnss entry to support wifi
|
|
Tweak and add some regulator entries that are needed to
|
|
support wifi.
|
|
|
|
The values here were taken from:
|
|
arch/arm/mach-msm/asustek/flo/board-flo-regulator.c
|
|
in the AOSP msm 3.4 flo branch.
|
|
|
|
This also adds a wcnss entry so it gets enabled on the board.
