-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.

-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"
- followed by the common "amlogic,gx-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-codec@c8820000 {
- compatible = "amlogic,gxbb-vdec", "amlogic,gx-vdec";
- reg = <0x0 0xc8820000 0x0 0x10000>,
- <0x0 0xc110a580 0x0 0xe4>;
- reg-names = "dos", "esparser";
-
- interrupts = <GIC_SPI 44 IRQ_TYPE_EDGE_RISING>,
- <GIC_SPI 32 IRQ_TYPE_EDGE_RISING>;
- interrupt-names = "vdec", "esparser";
-
- amlogic,ao-sysctrl = <&sysctrl_AO>;
- amlogic,canvas = <&canvas>;
-
- clocks = <&clkc CLKID_DOS_PARSER>,
- <&clkc CLKID_DOS>,
- <&clkc CLKID_VDEC_1>,
- <&clkc CLKID_VDEC_HEVC>;
- clock-names = "dos_parser", "dos", "vdec_1", "vdec_hevc";
-
- resets = <&reset RESET_PARSER>;
- reset-names = "esparser";
-};
