This patchset converts the existing text bindings to YAML schemas.

Those bindings have a lot of texts, thus is interesting to convert.

All have been tested using :
$ make ARCH=arm64 dtbs_check

Issues with the amlogic arm64 DTs has already been identified thanks
to the validation scripts. The DT fixes will be pushed once these yaml
bindings are acked.

Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic Synopsys DW-HDMI specifics over to YAML schemas.

The original example and usage of clock-names uses a reversed "isfr"
and "iahb" clock-names, the rewritten YAML bindings uses the reversed
instead of fixing the device trees order.

The #sound-dai-cells optional property has been added to match this node
as a sound dai.

The port connection table has been dropped in favor of a description
of each port.

-Amlogic specific extensions to the Synopsys Designware HDMI Controller
-======================================================================
-
-The Amlogic Meson Synopsys Designware Integration is composed of :
-- A Synopsys DesignWare HDMI Controller IP
-- A TOP control block controlling the Clocks and PHY
-- A custom HDMI PHY in order to convert video to TMDS signal

-The HDMI TOP block only supports HPD sensing.
-The Synopsys HDMI Controller interrupt is routed through the

-Communication to the TOP Block and the Synopsys HDMI Controller is done
-via a pair of dedicated addr+read/write registers.
-The HDMI PHY is configured by registers in the HHI register block.
-
-Pixel data arrives in 4:4:4 format from the VENC block and the VPU HDMI mux
-selects either the ENCI encoder for the 576i or 480i formats or the ENCP
-encoder for all the other formats including interlaced HD formats.
-
-The VENC uses a DVI encoder on top of the ENCI or ENCP encoders to generate
-DVI timings for the HDMI controller.
-
-Amlogic Meson GXBB, GXL and GXM SoCs families embeds the Synopsys DesignWare
-HDMI TX IP version 2.01a with HDCP and I2C & S/PDIF

-
-Required properties:
-- compatible: value should be different for each SoC family as :

-	- G12A (S905X2, S905Y2, S905D2) : "amlogic,meson-g12a-dw-hdmi"
-- reg: Physical base address and length of the controller's registers.
-- interrupts: The HDMI interrupt number
-- clocks, clock-names : must have the phandles to the HDMI iahb and isfr clocks,
-  and the Amlogic Meson venci clocks as described in
-  Documentation/devicetree/bindings/clock/clock-bindings.txt,
-  the clocks are soc specific, the clock-names should be "iahb", "isfr", "venci"
-- resets, resets-names: must have the phandles to the HDMI apb, glue and phy
-  resets as described in :
-  Documentation/devicetree/bindings/reset/reset.txt,
-  the reset-names should be "hdmitx_apb", "hdmitx", "hdmitx_phy"

-Optional properties:
-- hdmi-supply: Optional phandle to an external 5V regulator to power the HDMI
-  logic, as described in the file ../regulator/regulator.txt
-
-Required nodes:
-
-The connections to the HDMI ports are modeled using the OF graph
-bindings specified in Documentation/devicetree/bindings/graph.txt.

-The following table lists for each supported model the port number
-corresponding to each HDMI output and input.

Now that we have the DT validation in place, let's convert the device tree
bindings for the Amlogic Display Controller over to YAML schemas.

The original example has a leftover "dmc" memory cell, that has been
removed in the yaml rewrite.

The port connection table has been dropped in favor of a description
of each port.

-Amlogic Meson Display Controller
-================================
-
-The Amlogic Meson Display controller is composed of several components
-that are going to be documented below:
-
-DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|
-   | vd1   _______     _____________    _________________     |               |

-M  |-------|______|----|____________|   |________________|    |               |
-___|__________________________________________________________|_______________|
-
-
-VIU: Video Input Unit
----------------------
-
-The Video Input Unit is in charge of the pixel scanout from the DDR memory.
-It fetches the frames addresses, stride and parameters from the "Canvas" memory.
-This part is also in charge of the CSC (Colorspace Conversion).
-It can handle 2 OSD Planes and 2 Video Planes.
-
-VPP: Video Post Processing
---------------------------
-
-The Video Post Processing is in charge of the scaling and blending of the
-various planes into a single pixel stream.
-There is a special "pre-blending" used by the video planes with a dedicated
-scaler and a "post-blending" to merge with the OSD Planes.
-The OSD planes also have a dedicated scaler for one of the OSD.
-
-VENC: Video Encoders
---------------------
-
-The VENC is composed of the multiple pixel encoders :
- - ENCI : Interlace Video encoder for CVBS and Interlace HDMI
- - ENCP : Progressive Video Encoder for HDMI
- - ENCL : LCD LVDS Encoder
-The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
-tree and provides the scanout clock to the VPP and VIU.
-The ENCI is connected to a single VDAC for Composite Output.
-The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
-
-Device Tree Bindings:
----------------------
-
-VPU: Video Processing Unit
---------------------------
-
-Required properties:
-- compatible: value should be different for each SoC family as :
-	- GXBB (S905) : "amlogic,meson-gxbb-vpu"
-	- GXL (S905X, S905D) : "amlogic,meson-gxl-vpu"
-	- GXM (S912) : "amlogic,meson-gxm-vpu"
-	followed by the common "amlogic,meson-gx-vpu"
-	- G12A (S905X2, S905Y2, S905D2) : "amlogic,meson-g12a-vpu"
-- reg: base address and size of he following memory-mapped regions :
-	- vpu
-	- hhi
-- reg-names: should contain the names of the previous memory regions
-- interrupts: should contain the VENC Vsync interrupt number
-- amlogic,canvas: phandle to canvas provider node as described in the file
-	../soc/amlogic/amlogic,canvas.txt
-
-Optional properties:
-- power-domains: Optional phandle to associated power domain as described in
-	the file ../power/power_domain.txt
-
-Required nodes:
-
-The connections to the VPU output video ports are modeled using the OF graph
-bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-The following table lists for each supported model the port number
-corresponding to each VPU output.
-
-		Port 0		Port 1
------------------------------------------
- S905 (GXBB)	CVBS VDAC	HDMI-TX
- S905X (GXL)	CVBS VDAC	HDMI-TX
- S905D (GXL)	CVBS VDAC	HDMI-TX
- S912 (GXM)	CVBS VDAC	HDMI-TX
- S905X2 (G12A)	CVBS VDAC	HDMI-TX
- S905Y2 (G12A)	CVBS VDAC	HDMI-TX
- S905D2 (G12A)	CVBS VDAC	HDMI-TX

-
-tv-connector {
-	compatible = "composite-video-connector";
-
-	port {
-		tv_connector_in: endpoint {
-			remote-endpoint = <&cvbs_vdac_out>;

-vpu: vpu@d0100000 {

+
+
+  VIU: Video Input Unit
+  ---------------------
+
+  The Video Input Unit is in charge of the pixel scanout from the DDR memory.
+  It fetches the frames addresses, stride and parameters from the "Canvas" memory.
+  This part is also in charge of the CSC (Colorspace Conversion).
+  It can handle 2 OSD Planes and 2 Video Planes.
+
+  VPP: Video Post Processing
+  --------------------------
+
+  The Video Post Processing is in charge of the scaling and blending of the
+  various planes into a single pixel stream.
+  There is a special "pre-blending" used by the video planes with a dedicated
+  scaler and a "post-blending" to merge with the OSD Planes.
+  The OSD planes also have a dedicated scaler for one of the OSD.
+
+  VENC: Video Encoders
+  --------------------
+
+  The VENC is composed of the multiple pixel encoders
+   - ENCI : Interlace Video encoder for CVBS and Interlace HDMI
+   - ENCP : Progressive Video Encoder for HDMI
+   - ENCL : LCD LVDS Encoder
+  The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
+  tree and provides the scanout clock to the VPP and VIU.
+  The ENCI is connected to a single VDAC for Composite Output.
+  The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
