-* 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>;
-};
