This a repost of the previous RFC at [1] with fixes, the following patches will
be sent via a PULL Request once the Amlogic maintainer acks and takes the DT
patches to avoid merges conflicts.
The Amlogic Meson SoCs embeds a Video Processing Unit able to output at least
a Composite/CVBS Video with embedded VDAC and an HDMI Link with Embedded HDMI
Transceiver.
Thus, the current driver does not support HDMI yet.
The Video Processig Unit is composed of multiple modules like the Video
Input Unit and the Video Post Processing that can be associated to a
CRTC with Planes management.
The last Unit is the Venc that embeds at least 3 Encoders, ENCI for Interlace
Video used by CVBS or HDMI, ENCP for Progressive Video used by the HDMI
Transceiver and ENCL for LCD Display.
The LCD Display is not planned to be supported on the Meson GX Family.
This driver is a DRM/KMS driver using the following DRM components :
- GEM-CMA
- PRIME-CMA
- Atomic Modesetting
- FBDev-CMA
For the following SoCs :
- GXBB Family (S905)
- GXL Family (S905X, S905D)
- GXM Family (S912)
The current driver only supports the CVBS PAL/NTSC output modes, but the
CRTC/Planes management should support bigger modes.
But Advanced Colorspace Conversion, Scaling and HDMI Modes will be added in
a second time.
The Device Tree bindings makes use of the endpoints video interface definitions
to connect to the optional CVBS and in the future the HDMI Connector nodes.
The driver has been tested with Xorg modesetting driver and Weston DRM backend.
Changes since RFC at [1] :
- Add maintainers entry
- Move all Plane and CRTC code from backend to corresponding DRM code
- Keep only init and common code in backend source files
- Move the CVBS encoder out of the CVBS DT node, only keep the connector
- Various cleanups using DRM helpers
- Cleanup of copyright headers
- Fixup of bindings documentation

+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 _______ _____________ _________________ | |
+D |-------| |----| | | | | HDMI PLL |
+D | vd2 | VIU | | Video Post | | Video Encoders |<---|-----VCLK |
+R |-------| |----| Processing | | | | |
+ | osd2 | | | |---| Enci ----------|----|-----VDAC------|
+R |-------| CSC |----| Scalers | | Encp ----------|----|----HDMI-TX----|
+A | osd1 | | | Blenders | | Encl ----------|----|---------------|
+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"
+- reg: base address and size of he following memory-mapped regions :
+ - vpu
+ - hhi
+ - dmc
+- reg-names: should contain the names of the previous memory regions
+- interrupts: should contain the VENC Vsync interrupt number
+
+- ports: A ports node with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The
+ second port should be the output endpoints for VENC connectors.
+
+CBVS Output
+-----------
+
+The VENC can output Composite/CVBS output via a dedicated VDAC, usage of such
+Composite output is optional.
+
+Required properties:
+- compatible: value should be different for each SoC family as :
+ - GXBB (S905) : "amlogic,meson-gxbb-cvbs"
+ - GXL (S905X, S905D) : "amlogic,meson-gxl-cvbs"
+ - GXM (S912) : "amlogic,meson-gxm-cvbs"
+ followed by the common "amlogic,meson-gx-cvbs"
+
+- ports: A ports node with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The
+ first port should be the input endpoints, connected ot the VPU node.
+
+Example:
+
+venc_cvbs: venc-cvbs {
+ compatible = "amlogic,meson-gxbb-cvbs";
+ status = "okay";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ enc_cvbs_in: port at 0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0>;
+
+ venc_cvbs_in_vpu: endpoint at 0 {
+ reg = <0>;
+ remote-endpoint = <&vpu_out_venc_cvbs>;
+ };
+ };
+ };
+};
+
+vpu: vpu at d0100000 {
+ compatible = "amlogic,meson-gxbb-vpu";
+ reg = <0x0 0xd0100000 0x0 0x100000>,
+ <0x0 0xc883c000 0x0 0x1000>,
+ <0x0 0xc8838000 0x0 0x1000>;
+ reg-names = "base", "hhi", "dmc";
+ interrupts = <GIC_SPI 3 IRQ_TYPE_EDGE_RISING>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ vpu_out: port at 1 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <1>;
+
+ vpu_out_venc_cvbs: endpoint at 0 {
+ reg = <0>;
+ remote-endpoint = <&venc_cvbs_in_vpu>;
+ };
+ };
+ };

I think this is all reasonable, once you have an ack from DT maintainers
pls send the pull request to Dave.

Hi Neil,
Thank you for the patch.

Still no registers here ?

Nitpicking, you don't need a label here as ports are never referenced by
phandle. Same for the vpu node below.

And there's no requirement to number the endpoint if there's a single one of
them (but it's not forbidden either).

Or is this the internal video encoder, not the HHI VDAC ? If so, haven't we
decided when discussing the previous version that there's no need for a DT
node to model the video encoder as it's part of the VPU ?
