-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;
- };
-}

- #sound-dai-cells = <1>;
- reg = <0x0 0x10500000 0x80000>;
- memory-region = <&reserved_mem>;
