-* Amlogic Meson AO-CEC driver
-
-The Amlogic Meson AO-CEC module is present is Amlogic SoCs and its purpose is
-to handle communication between HDMI connected devices over the CEC bus.
-
-Required properties:
- - compatible : value should be following depending on the SoC :
- For GXBB, GXL, GXM, G12A and SM1 (AO_CEC_A module) :
- "amlogic,meson-gx-ao-cec"
- For G12A (AO_CEC_B module) :
- "amlogic,meson-g12a-ao-cec"
- For SM1 (AO_CEC_B module) :
- "amlogic,meson-sm1-ao-cec"
-
- - reg : Physical base address of the IP registers and length of memory
- mapped region.
-
- - interrupts : AO-CEC interrupt number to the CPU.
- - clocks : from common clock binding: handle to AO-CEC clock.
- - clock-names : from common clock binding, must contain :
- For GXBB, GXL, GXM, G12A and SM1 (AO_CEC_A module) :
- - "core"
- For G12A, SM1 (AO_CEC_B module) :
- - "oscin"
- corresponding to entry in the clocks property.
- - hdmi-phandle: phandle to the HDMI controller
-
-Example:
-
-cec_AO: cec@100 {
- compatible = "amlogic,meson-gx-ao-cec";
- reg = <0x0 0x00100 0x0 0x14>;
- interrupts = <GIC_SPI 199 IRQ_TYPE_EDGE_RISING>;
- clocks = <&clkc_AO CLKID_AO_CEC_32K>;
- clock-names = "core";
- hdmi-phandle = <&hdmi_tx>;
-};
