Convert the ADV7511/11w/13/33/35 DT bindings to json-schema. The
original binding has been split into two files: adi,adv7511.yaml for
ADV7511/11W/13 and adi,adv7533.yaml for ADV7533/35.

This causes lots of failures like:

    arm/boot/dts/r8a7743-iwg20d-q7-dbcm-ca.dt.yaml: hdmi@39:
'avdd-supply' is a required property

Should all supplies be required?
Looking at the driver, missing supplies are automatically replaced by
dummy regulators by the regulator framework.

Generally speaking, I like DT bindings to be descriptive of the
hardware, and thus require power supplies that are needed for the device
to function, even if they are fixed supplies.

This being said, I think there's also room to group some power supplies
together in the bindings, when they are not meant by the device to be
controlled separately. In this specific case, we also need to take into
account that the adv7511 and adv7533 have different supplies.

Thanks for the review, guys. Yes, there were some dtbs check warnings to
be expected, the consensus in a previous version of the patch was that
that shouldn't be a blocker for a binding conversion and that the *.dts
definitions should eventually be fixed to comply with the binding, which
is, IMO, a more reasonable process to keep the binding conversion
effort progressing.

Cheers,
Ricardo

-Analog Devices ADV7511(W)/13/33/35 HDMI Encoders
-------------------------------------------------
-
-The ADV7511, ADV7511W, ADV7513, ADV7533 and ADV7535 are HDMI audio and video
-transmitters compatible with HDMI 1.4 and DVI 1.0. They support color space
-conversion, S/PDIF, CEC and HDCP. ADV7533/5 supports the DSI interface for input
-pixels, while the others support RGB interface.
-
-Required properties:
-
-- compatible: Should be one of:
-		"adi,adv7511"
-		"adi,adv7511w"
-		"adi,adv7513"
-		"adi,adv7533"
-		"adi,adv7535"
-
-- reg: I2C slave addresses
-  The ADV7511 internal registers are split into four pages exposed through
-  different I2C addresses, creating four register maps. Each map has it own
-  I2C address and acts as a standard slave device on the I2C bus. The main
-  address is mandatory, others are optional and revert to defaults if not
-  specified.
-
-
-The ADV7511 supports a large number of input data formats that differ by their
-color depth, color format, clock mode, bit justification and random
-arrangement of components on the data bus. The combination of the following
-properties describe the input and map directly to the video input tables of the
-ADV7511 datasheet that document all the supported combinations.
-
-- adi,input-depth: Number of bits per color component at the input (8, 10 or
-  12).
-- adi,input-colorspace: The input color space, one of "rgb", "yuv422" or
-  "yuv444".
-- adi,input-clock: The input clock type, one of "1x" (one clock cycle per
-  pixel), "2x" (two clock cycles per pixel), "ddr" (one clock cycle per pixel,
-  data driven on both edges).
-
-The following input format properties are required except in "rgb 1x" and
-"yuv444 1x" modes, in which case they must not be specified.
-
-- adi,input-style: The input components arrangement variant (1, 2 or 3), as
-  listed in the input format tables in the datasheet.
-- adi,input-justification: The input bit justification ("left", "evenly",
-  "right").
-
-- avdd-supply: A 1.8V supply that powers up the AVDD pin on the chip.
-- dvdd-supply: A 1.8V supply that powers up the DVDD pin on the chip.
-- pvdd-supply: A 1.8V supply that powers up the PVDD pin on the chip.
-- dvdd-3v-supply: A 3.3V supply that powers up the pin called DVDD_3V
-  on the chip.
-- bgvdd-supply: A 1.8V supply that powers up the BGVDD pin. This is
-  needed only for ADV7511.
-
-The following properties are required for ADV7533 and ADV7535:
-
-- adi,dsi-lanes: Number of DSI data lanes connected to the DSI host. It should
-  be one of 1, 2, 3 or 4.
-- a2vdd-supply: 1.8V supply that powers up the A2VDD pin on the chip.
-- v3p3-supply: A 3.3V supply that powers up the V3P3 pin on the chip.
-- v1p2-supply: A supply that powers up the V1P2 pin on the chip. It can be
-  either 1.2V or 1.8V for ADV7533 but only 1.8V for ADV7535.
-
-Optional properties:
-
-- interrupts: Specifier for the ADV7511 interrupt
-- pd-gpios: Specifier for the GPIO connected to the power down signal
-
-- adi,clock-delay: Video data clock delay relative to the pixel clock, in ps
-  (-1200 ps .. 1600 ps). Defaults to no delay.
-- adi,embedded-sync: The input uses synchronization signals embedded in the
-  data stream (similar to BT.656). Defaults to separate H/V synchronization
-  signals.
-- adi,disable-timing-generator: Only for ADV7533 and ADV7535. Disables the
-  internal timing generator. The chip will rely on the sync signals in the
-  DSI data lanes, rather than generate its own timings for HDMI output.
-- clocks: from common clock binding: reference to the CEC clock.
-- clock-names: from common clock binding: must be "cec".
-- reg-names : Names of maps with programmable addresses.
-	It can contain any map needing a non-default address.
-	Possible maps names are : "main", "edid", "cec", "packet"
-
-Required nodes:
-
-The ADV7511 has two video ports. Their connections are modelled using the OF
-graph bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-- Video port 0 for the RGB, YUV or DSI input. In the case of ADV7533/5, the
-  remote endpoint phandle should be a reference to a valid mipi_dsi_host device
-  node.
-- Video port 1 for the HDMI output
-- Audio port 2 for the HDMI audio input
-
-

+description: |
+  The ADV7533 and ADV7535 are HDMI audio and video transmitters
+  compatible with HDMI 1.4 and DVI 1.0. They support color space
+  conversion, S/PDIF, CEC and HDCP. The transmitter input is MIPI DSI.

+      I2C slave addresses.
+
+      The ADV7533/35 internal registers are split into four pages
+      exposed through different I2C addresses, creating four register
+      maps. Each map has it own I2C address and acts as a standard slave
+      device on the I2C bus. The main address is mandatory, others are
+      optional and revert to defaults if not specified.
