3Required properties:
4
5  - compatible : must contain one of "cirrus,cs42448" and "cirrus,cs42888"
6
7  - reg : the I2C address of the device for I2C
8
9  - clocks : a list of phandles + clock-specifiers, one for each entry in
10    clock-names
11
12  - clock-names : must contain "mclk"
13
14  - VA-supply, VD-supply, VLS-supply, VLC-supply: power supplies for the device,
15    as covered in Documentation/devicetree/bindings/regulator/regulator.txt
16
17Optional properties:
18
19  - reset-gpios : a GPIO spec to define which pin is connected to the chip's
20    !RESET pin
