[PATCH 19/29] ARM: dts: lager: Add entries for VIN HDMI input support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: William Towle <william.towle@xxxxxxxxxxxxxxx>

Add DT entries for vin0, vin0_pins, and adv7612.

Sets the 'default-input' property for ADV7612, enabling image and video
capture without the need to have userspace specifying routing.

[uli: added interrupt, renamed endpoint, merged default-input]
