1* Amlogic Meson AO-CEC driver 2 3The Amlogic Meson AO-CEC module is present is Amlogic SoCs and its purpose is 4to handle communication between HDMI connected devices over the CEC bus. 5 6Required properties: 7 - compatible : value should be following 8 "amlogic,meson-gx-ao-cec" 9 10 - reg : Physical base address of the IP registers and length of memory 11 mapped region. 12 13 - interrupts : AO-CEC interrupt number to the CPU. 14 - clocks : from common clock binding: handle to AO-CEC clock. 15 - clock-names : from common clock binding: must contain "core", 16 corresponding to entry in the clocks property. 17 - hdmi-phandle: phandle to the HDMI controller 18 19Example: 20 21cec_AO: cec@100 { 22 compatible = "amlogic,meson-gx-ao-cec"; 23 reg = <0x0 0x00100 0x0 0x14>; 24 interrupts = <GIC_SPI 199 IRQ_TYPE_EDGE_RISING>; 25 clocks = <&clkc_AO CLKID_AO_CEC_32K>; 26 clock-names = "core"; 27 hdmi-phandle = <&hdmi_tx>; 28}; 29
