* 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
Optional:
- needs-hpd : if present the CEC support is only available when the HPD
is high. Some boards only let the CEC pin through if the HPD is high, for
example if there is a level converter that uses the HPD to power up
or down.
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>;
status = "okay";
};
