Audio codec controlled by ChromeOS EC
Google's ChromeOS EC codec is a digital mic codec provided by the
Embedded Controller (EC) and is controlled via a host-command interface.
An EC codec node should only be found as a sub-node of the EC node (see
Documentation/devicetree/bindings/mfd/cros-ec.txt).
Required properties:
- compatible: Must contain "google,cros-ec-codec"
- #sound-dai-cells: Should be 1. The cell specifies number of DAIs.
Optional properties:
- reg: Pysical base address and length of shared memory region from EC.
It contains 3 unsigned 32-bit integer. The first 2 integers
combine to become an unsigned 64-bit physical address. The last
one integer is length of the shared memory.
- memory-region: Shared memory region to EC. A "shared-dma-pool". See
../reserved-memory/reserved-memory.txt for details.
Example:
{
...
reserved_mem: reserved_mem {
compatible = "shared-dma-pool";
reg = <0 0x52800000 0 0x100000>;
no-map;
};
}
cros-ec@0 {
compatible = "google,cros-ec-spi";
...
cros_ec_codec: ec-codec {
compatible = "google,cros-ec-codec";
#sound-dai-cells = <1>;
reg = <0x0 0x10500000 0x80000>;
memory-region = <&reserved_mem>;
};
};
