+Device-tree bindings for the Allegro DVT video IP codecs present in the Xilinx
+ZynqMP SoC. The IP core may either be a H.264/H.265 encoder or H.264/H.265
+decoder ip core.
+
+Each actual codec engines is controlled by a microcontroller (MCU). Host
+software uses a provided mailbox interface to communicate with the MCU. The
+MCU share an interrupt.
+
+Required properties:
+  - compatible: value should be one of the following
+    "allegro,al5e-1.1", "allegro,al5e": encoder IP core
+    "allegro,al5d-1.1", "allegro,al5d": decoder IP core
+  - reg: base and length of the memory mapped register region and base and
+    length of the memory mapped sram
+  - reg-names: must include "regs" and "sram"
+  - interrupts: shared interrupt from the MCUs to the processing system
+  - clocks: must contain an entry for each entry in clock-names
+  - clock-names: must include "core_clk", "mcu_clk", "m_axi_core_aclk",
+    "m_axi_mcu_aclk", "s_axi_lite_aclk"
+
+Example:
+	al5e: video-codec@a0009000 {
+		compatible = "allegro,al5e-1.1", "allegro,al5e";
+		reg = <0 0xa0009000 0 0x1000>,

+Amlogic Video Decoder
+================================
+
+The video decoding IP lies within the DOS memory region,
+except for the hardware bitstream parser that makes use of an undocumented
+region.
+
+It makes use of the following blocks:
+
+- ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
+then feed from this VIFIFO.
+- VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
+- VDEC_HEVC can decode HEVC and VP9.
+
+Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
+concurrently.
+
+Device Tree Bindings:
+---------------------
+
+VDEC: Video Decoder
+--------------------------
+
+Required properties:
+- compatible: value should be different for each SoC family as :
+	- GXBB (S905) : "amlogic,gxbb-vdec"
+	- GXL (S905X, S905D) : "amlogic,gxl-vdec"
+	- GXM (S912) : "amlogic,gxm-vdec"
+- reg: base address and size of he following memory-mapped regions :
+	- dos
+	- esparser
+- reg-names: should contain the names of the previous memory regions
+- interrupts: should contain the following IRQs:
+	- vdec
+	- esparser
+- interrupt-names: should contain the names of the previous interrupts
+- amlogic,ao-sysctrl: should point to the AOBUS sysctrl node
+- amlogic,canvas: should point to a canvas provider node
+- clocks: should contain the following clocks :
+	- dos_parser
+	- dos
+	- vdec_1
+	- vdec_hevc
+- clock-names: should contain the names of the previous clocks
+- resets: should contain the parser reset
+- reset-names: should be "esparser"
+
+Example:
+
+vdec: video-decoder@c8820000 {
+	compatible = "amlogic,gxbb-vdec";
+	reg = <0x0 0xc8820000 0x0 0x10000>,
