-* Samsung HDMI CEC driver
-
-The HDMI CEC module is present is Samsung SoCs and its purpose is to
-handle communication between HDMI connected devices over the CEC bus.
-
-Required properties:
-  - compatible : value should be following
-	"samsung,s5p-cec"
-
-  - reg : Physical base address of the IP registers and length of memory
-	  mapped region.
-
-  - interrupts : HDMI CEC interrupt number to the CPU.
-  - clocks : from common clock binding: handle to HDMI CEC clock.
-  - clock-names : from common clock binding: must contain "hdmicec",
-		  corresponding to entry in the clocks property.
-  - samsung,syscon-phandle - phandle to the PMU system controller
-  - hdmi-phandle - phandle to the HDMI controller, see also cec.txt.
-
-Optional:
-  - needs-hpd : if present the CEC support is only available when the HPD
-		is high. See cec.txt for more details.

For consistency with other DT bindings on Tegra, it'd be good to name
this nvidia,tegra114-cec.yaml since that's the first generation where
this IP was added. Not a big deal, though.

Again, for consistency with other bindings, NVIDIA is the preferred
spelling. It's not a big deal and could be fixed up in a subsequent
patch, there are a few other cases where the alternative spelling has
been used.

The rest looks okay, so either way:
