From 57b82d9e79d77442bae3d2c13b98ceccb39fe5e2 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/3] ARM: dts: imx: ventana: set GW54xx PMIC swbst regulator
as always-on
The GW54xx PMIC swbst regulator is used for LVDS power, CANbus xceiver
and HDMI DDC and is enabled by the bootloader. Set the regulator to
always-on so that Linux doesn't turn it off thinking its not needed.
