Subject: [PATCH 1/3] ARM: dts: imx: ventana: GW54xx PMIC swbst reg always-on
Date: Fri,  6 Nov 2015 14:40:30 -0800	[thread overview]
Message-ID: <1446849632-20333-2-git-send-email-tharvey@gateworks.com> (raw)
In-Reply-To: <1446849632-20333-1-git-send-email-tharvey@gateworks.com>

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.
