* 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>; };
