[PATCHv6 1/3] ARM:dt-bindings Intel FPGA Video and Image Processing Suite

["Hean-Loong, Ong" <hean.loong.ong@intel.com>]

From: Ong Hean Loong <hean.loong.ong@intel.com>

Device tree binding for Intel FPGA Video and Image
Processing Suite. The binding involved would be generated
from the Altera (Intel) Qsys system. The bindings would
set the max width, max height, buts per pixel and memory
port width. The device tree binding only supports the Intel
Arria10 devkit and its variants. Vendor name retained as
altr.

+Intel Video and Image Processing(VIP) Frame Buffer II bindings
+
+Supported hardware: Intel FPGA SoC Arria10 and above with display port IP
+
+The hardware associated with this device tree is a SoC FPGA.
+Where there is an microprocessor and a FPGA device.
+The microprocessor would host the OS while the FPGA device runs
+on its individual IP firmware. The Intel VIP Frame Buffer II
+system would be driving data from the to the FPGA device
+programmed with the Frame Buffer II IP to render pixels to be streamed
+to the Display Port connector.
+
+The Frame Buffer II device is a simple frame buffer device. The device
+contains the display properties and the bridge or connector register.
+The output for this device currently is a dedicated to a single Display Port.
+Currently the max resolution supported is 1280 x 720 at 60Hz.
+
+More information the FPGA video IP component can be acquired from
+https://www.altera.com/content/dam/altera-www/global/en_US/pdfs\
+/literature/ug/ug_vip.pdf
+
+New bindings:
+=============
+Required properties:
+----------------------------
+- compatible: "altr,vip-frame-buffer-2.0"
+- reg: Physical base address and length of the framebuffer controller's
+	registers.
+- altr,max-width: The maximum width of the framebuffer in pixels.
+- altr,max-height: The maximum height of the framebuffer in pixels.
+- altr,mem-port-width: the bus width of the avalon master port
+	on the frame reader
+
+Example:
+----------------------------
+       dp_0_frame_buf: display-controller@100000280 {
+                       compatible = "altr,vip-frame-buffer-2.0";
+                       reg = <0x00000001 0x00000280 0x00000040>;
+                       altr,max-width = <1280>;
+                       altr,max-height = <720>;
+                       altr,mem-port-width = <128>;
+       };
