-* 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.
-
-Example:
-
-hdmicec: cec@100b0000 {
-	compatible = "samsung,s5p-cec";
-	reg = <0x100B0000 0x200>;
-	interrupts = <0 114 0>;
-	clocks = <&clock CLK_HDMI_CEC>;
-	clock-names = "hdmicec";
-	samsung,syscon-phandle = <&pmu_system_controller>;
-	hdmi-phandle = <&hdmi>;
-	pinctrl-names = "default";
-	pinctrl-0 = <&hdmi_cec>;
-};
