-Cirrus Logic Madera class audio codecs Multi-Functional Device
-
-These devices are audio SoCs with extensive digital capabilities and a range
-of analogue I/O.
-
-See also the child driver bindings in:
-bindings/pinctrl/cirrus,madera-pinctrl.txt
-bindings/regulator/arizona-regulator.txt

-
-Required properties:
-
-  - compatible : One of the following chip-specific strings:
-        "cirrus,cs47l15"

-
-  - reg : I2C slave address when connected using I2C, chip select number when
-    using SPI.
-
-  - DCVDD-supply : Power supply for the device as defined in
-    bindings/regulator/regulator.txt
-    Mandatory on CS47L15, CS47L35, CS47L90, CS47L91, CS42L92, CS47L92, CS47L93
-    Optional on CS47L85, WM1840
-
-  - AVDD-supply, DBVDD1-supply, DBVDD2-supply, CPVDD1-supply, CPVDD2-supply :
-    Power supplies for the device
-

-    (CS47L85, CS47L90, CS47L91, WM1840)
-
-  - SPKVDDL-supply, SPKVDDR-supply : Power supplies for the device
-    (CS47L85, WM1840)
-
-  - SPKVDD-supply : Power supply for the device
-    (CS47L15, CS47L35)
-
-  - interrupt-controller : Indicates that this device is an interrupt controller
-
-  - #interrupt-cells: the number of cells to describe an IRQ, must be 2.
-    The first cell is the IRQ number.
-    The second cell is the flags, encoded as the trigger masks from
-    bindings/interrupt-controller/interrupts.txt
-
-  - gpio-controller : Indicates this device is a GPIO controller.
-
-  - #gpio-cells : Must be 2. The first cell is the pin number. The second cell
-    is reserved for future use and must be zero
-
-  - interrupt-parent : The parent interrupt controller.
-
-  - interrupts : The interrupt line the /IRQ signal for the device is
-    connected to.
-
-Optional properties:
-
-  - MICVDD-supply : Power supply, only need to be specified if
-    powered externally
-
-  - reset-gpios : One entry specifying the GPIO controlling /RESET.
-    As defined in bindings/gpio.txt.
-    Although optional, it is strongly recommended to use a hardware reset
-
-  - clocks: Should reference the clocks supplied on MCLK1, MCLK2 and MCLK3
-  - clock-names: May contain up to three strings:
-      "mclk1" for the clock supplied on MCLK1, recommended to be a high
-      quality audio reference clock

-    (all codecs)
-
-    One for each output pin (MICBIAS1A, MIBCIAS1B, MICBIAS2A, ...)
-    (all except CS47L85, WM1840)
-
-    The following following additional property is supported for the generator
-    nodes:
-      - cirrus,ext-cap : Set to 1 if the MICBIAS has external decoupling
-        capacitors attached.
-
-Optional child nodes:
-    micvdd : Node containing initialization data for the micvdd regulator
-    See bindings/regulator/arizona-regulator.txt
