Convert the Wolfson WM1811/WM8994/WM8958 audio codecs bindings to DT
schema.

Changes against original binding:
1. Add missing LDO1VDD-supply and LDO2VDD-supply.
2. Use "gpios" suffix for wlf,ldo1ena and wlf,ldo2ena (Linux kernel's
   gpiolib already looks for both variants).
3. Do not require AVDD1-supply and DCVDD-supply, because at least on
   Arndale board with Exynos5250 these are being supplied by internal
   LDOs.

Changes since v1:
1. Add LDO2VDD-supply.
2. Do not require AVDD1-supply on WM8994.
3. Move requiring of common supplies to top-level "required:".
4. Add Rb tag.

DTS is being corrected here:

Thanks!

[1/1] ASoC: dt-bindings: wlf,wm8994: Convert to dtschema
      commit: 80404e4e13882cf3037577e4a3451a61d54f58db

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

-          number for SPI.
-
-  - gpio-controller : Indicates this device is a GPIO controller.
-  - #gpio-cells : Must be 2. The first cell is the pin number and the
-    second cell is used to specify optional parameters (currently unused).
-

-    The first cell is the IRQ number.
-    The second cell is the flags, encoded as the trigger masks from

-  - clocks : A list of up to two phandle and clock specifier pairs
-  - clock-names : A list of clock names sorted in the same order as clocks.
-                  Valid clock names are "MCLK1" and "MCLK2".
-
-  - wlf,gpio-cfg : A list of GPIO configuration register values. If absent,
-    no configuration of these registers is performed. If any value is
-    over 0xffff then the register will be left as default. If present 11
-    values must be supplied.
