      1WM1811/WM8994/WM8958 audio CODEC
      2
      3These devices support both I2C and SPI (configured with pin strapping
      4on the board).
      5
      6Required properties:
      7
      8  - compatible : One of "wlf,wm1811", "wlf,wm8994" or "wlf,wm8958".
      9
     10  - reg : the I2C address of the device for I2C, the chip select
     11          number for SPI.
     12
     13  - gpio-controller : Indicates this device is a GPIO controller.
     14  - #gpio-cells : Must be 2. The first cell is the pin number and the
     15    second cell is used to specify optional parameters (currently unused).
     16
     17  - power supplies for the device, as covered in
     18    Documentation/devicetree/bindings/regulator/regulator.txt, depending
     19    on compatible:
     20    - for wlf,wm1811 and wlf,wm8958:
     21      AVDD1-supply, AVDD2-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply,
     22      DCVDD-supply, CPVDD-supply, SPKVDD1-supply, SPKVDD2-supply
     23    - for wlf,wm8994:
     24      AVDD1-supply, AVDD2-supply, DBVDD-supply, DCVDD-supply, CPVDD-supply,
     25      SPKVDD1-supply, SPKVDD2-supply
     26
     27Optional properties:
     28
     29  - interrupts : The interrupt line the IRQ signal for the device is
     30    connected to.  This is optional, if it is not connected then none
     31    of the interrupt related properties should be specified.
     32  - interrupt-controller : These devices contain interrupt controllers
     33    and may provide interrupt services to other devices if they have an
     34    interrupt line connected.
     35  - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
     36    The first cell is the IRQ number.
     37    The second cell is the flags, encoded as the trigger masks from
     38    Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
     39
     40  - clocks : A list of up to two phandle and clock specifier pairs
     41  - clock-names : A list of clock names sorted in the same order as clocks.
     42                  Valid clock names are "MCLK1" and "MCLK2".
     43
     44  - wlf,gpio-cfg : A list of GPIO configuration register values. If absent,
     45    no configuration of these registers is performed. If any value is
     46    over 0xffff then the register will be left as default. If present 11
     47    values must be supplied.
     48
     49  - wlf,micbias-cfg : Two MICBIAS register values for WM1811 or
     50    WM8958.  If absent the register defaults will be used.
     51
     52  - wlf,ldo1ena : GPIO specifier for control of LDO1ENA input to device.
     53  - wlf,ldo2ena : GPIO specifier for control of LDO2ENA input to device.
     54
     55  - wlf,lineout1-se : If present LINEOUT1 is in single ended mode.
     56  - wlf,lineout2-se : If present LINEOUT2 is in single ended mode.
     57
     58  - wlf,lineout1-feedback : If present LINEOUT1 has common mode feedback
     59    connected.
     60  - wlf,lineout2-feedback : If present LINEOUT2 has common mode feedback
     61    connected.
     62
     63  - wlf,ldoena-always-driven : If present LDOENA is always driven.
     64
     65  - wlf,spkmode-pu : If present enable the internal pull-up resistor on
     66    the SPKMODE pin.
     67
     68  - wlf,csnaddr-pd : If present enable the internal pull-down resistor on
     69    the CS/ADDR pin.
