    1 * Samsung HDMI CEC driver
    2 
    3 The HDMI CEC module is present is Samsung SoCs and its purpose is to
    4 handle communication between HDMI connected devices over the CEC bus.
    5 
    6 Required properties:
    7   - compatible : value should be following
    8         "samsung,s5p-cec"
    9 
   10   - reg : Physical base address of the IP registers and length of memory
   11           mapped region.
   12 
   13   - interrupts : HDMI CEC interrupt number to the CPU.
   14   - clocks : from common clock binding: handle to HDMI CEC clock.
   15   - clock-names : from common clock binding: must contain "hdmicec",
   16                   corresponding to entry in the clocks property.
   17   - samsung,syscon-phandle - phandle to the PMU system controller
   18   - hdmi-phandle - phandle to the HDMI controller, see also cec.txt.
   19 
   20 Optional:
   21   - needs-hpd : if present the CEC support is only available when the HPD
   22                 is high. See cec.txt for more details.
   23 
   24 Example:
   25 
   26 hdmicec: cec@100b0000 {
   27         compatible = "samsung,s5p-cec";
   28         reg = <0x100B0000 0x200>;
   29         interrupts = <0 114 0>;
   30         clocks = <&clock CLK_HDMI_CEC>;
   31         clock-names = "hdmicec";
   32         samsung,syscon-phandle = <&pmu_system_controller>;
   33         hdmi-phandle = <&hdmi>;
   34         pinctrl-names = "default";
   35         pinctrl-0 = <&hdmi_cec>;
   36 };
