Socionext EVEA - UniPhier SoC internal codec driver
|
||||
|
||||
Required properties:
|
||||
- compatible : should be "socionext,uniphier-evea".
|
||||
- reg : offset and length of the register set for the device.
|
||||
- clock-names : should include following entries:
|
||||
"evea", "exiv"
|
||||
- clocks : a list of phandle, should contain an entry for each
|
||||
entries in clock-names.
|
||||
- reset-names : should include following entries:
|
||||
"evea", "exiv", "adamv"
|
||||
- resets : a list of phandle, should contain reset entries of
|
||||
reset-names.
|
||||
- #sound-dai-cells: should be 1.
|
||||
|
||||
Example:
|
||||
|
||||
codec {
|
||||
compatible = "socionext,uniphier-evea";
|
||||
reg = <0x57900000 0x1000>;
|
||||
clock-names = "evea", "exiv";
|
||||
clocks = <&sys_clk 41>, <&sys_clk 42>;
|
||||
reset-names = "evea", "exiv", "adamv";
|
||||
resets = <&sys_rst 41>, <&sys_rst 42>, <&adamv_rst 0>;
|
||||
#sound-dai-cells = <1>;
|
||||
