* 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 and G12A (AO_CEC_A module) :
"amlogic,meson-gx-ao-cec"
For G12A (AO_CEC_B module) :
"amlogic,meson-g12a-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 and G12A (AO_CEC_A module) :
- "core"
For G12A (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>;
};
