+       - interrupts, interrupt-parent: interrupt specifier of INT pin
+       - reset-gpios: gpio specifier of RESET pin
+       - clocks, clock-names: specification and name of "xtal" clock
+       - video interfaces: Device node can contain video interface port
+                           node for HDMI encoder according to [1].
