[PATCH v3 0/9] Renesas R-Car DU HDMI support

[PATCH v3 0/9] Renesas R-Car DU HDMI support

[Laurent Pinchart]

Hello,

This patch set adds support for the HDMI output port present on the Renesas
Koelsch board. Doing so requires two components, a driver for the external
ADV7511W HDMI encoder, and support for HDMI encoders in the DU driver.

The HDMI encoder drivers uses the DRM slave encoder framework and the
component framework to communicate with the DU driver. The DT bindings are
based on the OF graph bindings to link the display controller and encoder.

The R-Car DU patches start with a bit of refactoring, to finally add HDMI
support in patch 5/9

The new adv7511 driver (patch 8/9) depends on decoupling EDID parsing from the
DDC I2C adapter (patch 6/9). It supports DT instantiation only (bindings are
documented in patch 7/9) for now. Platform data support could be added later
if needed. The code is based on Lars-Peter Clausen's adv7511 driver, with
heavy modifications.

The last patch instantiates the HDMI encoder in the Koelsch board DT file and
connects it to the DU output.

The patch series depends on Koelsch DU DT enablement (scheduled for merge in
v3.19-rc1). Dave, I'd like to get this merged in v3.19-rc1, how would you like
to proceed ? Could it go through Simon's Renesas tree ? There's a small risk
of conflict in drivers/gpu/drm/drm_edid.c, include/drm/drm_edid.h,
drivers/gpu/drm/i2c/Kconfig and drivers/gpu/drm/i2c/Makefile. Simon, could you
alternatively provide a stable branch with the required dependencies ?

Changes since v2:

- Name arguments to get_edid_block()

Changes since v1:

- Dropped Philipp Zabel's OF graph patches (the rcar-du-drm driver will be
  udpated to use for_each_endpoint_of_node when the implementation hits
  upstream)
- adv7511: Clarify the adi,input-format DT property documentation
- adv7511: Use map array to convert input style to hardware value
- adv7511: Fixed typos

For ease of testing and review I've pushed this series and its dependencies to
a git branch on

[PATCH v3 7/9] video: Add ADV751[13] DT bindings documentation

[Laurent Pinchart]

The ADV7511, ADV7511W and ADV7513 are HDMI audio and video transmitters
compatible with HDMI 1.4 and DVI 1.0. They're described in DT using the
OF graph bindings and a list of custom properties pertaining to the
input video bus configuration.

+Analog Device ADV7511(W)/13 HDMI Encoders
+-----------------------------------------
+
+The ADV7511, ADV7511W and ADV7513 are HDMI audio and video transmitters
+compatible with HDMI 1.4 and DVI 1.0. They support color space conversion,
+S/PDIF, CEC and HDCP.
+
+Required properties:
+
+- compatible: Should be one of "adi,adv7511", "adi,adv7511w" or "adi,adv7513"
+- reg: I2C slave address
+
+The ADV7511 supports a large number of input data formats that differ by their
+color depth, color format, clock mode, bit justification and random
+arrangement of components on the data bus. The combination of the following
+properties describe the input and map directly to the video input tables of the
+ADV7511 datasheet that document all the supported combinations.
+
+- adi,input-depth: Number of bits per color component at the input (8, 10 or
+  12).
+- adi,input-colorspace: The input color space, one of "rgb", "yuv422" or
+  "yuv444".
+- adi,input-clock: The input clock type, one of "1x" (one clock cycle per
+  pixel), "2x" (two clock cycles per pixel), "ddr" (one clock cycle per pixel,
+  data driven on both edges).
+
+The following input format properties are required except in "rgb 1x" and
+"yuv444 1x" modes, in which case they must not be specified.
+
+- adi,input-style: The input components arrangement variant (1, 2 or 3), as
+  listed in the input format tables in the datasheet.
+- adi,input-justification: The input bit justification ("left", "evenly",
+  "right").
+
+Optional properties:
+
+- interrupts: Specifier for the ADV7511 interrupt
+- pd-gpios: Specifier for the GPIO connected to the power down signal
+
+- adi,clock-delay: Video data clock delay relative to the pixel clock, in ps
+  (-1200 ps .. 1600 ps). Defaults to no delay.
+- adi,embedded-sync: The input uses synchronization signals embedded in the
+  data stream (similar to BT.656). Defaults to separate H/V synchronization
+  signals.
+
+Required nodes:
+
+The ADV7511 has two video ports. Their connections are modelled using the OF
+graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 for the RGB or YUV input
+- Video port 1 for the HDMI output
+
+
+Example
+-------
+
+	adv7511w: hdmi@39 {
+		compatible = "adi,adv7511w";
+		reg = <39>;
+		interrupt-parent = <&gpio3>;
+		interrupts = <29 IRQ_TYPE_EDGE_FALLING>;
+
+		adi,input-depth = <8>;
+		adi,input-colorspace = "rgb";
+		adi,input-clock = "1x";
+		adi,input-style = <1>;
+		adi,input-justification = "evenly";
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+				adv7511w_in: endpoint {
+					remote-endpoint = <&dpi_out>;
+				};
+			};
+
+			port@1 {
+				reg = <1>;
+				adv7511_out: endpoint {
+					remote-endpoint = <&hdmi_connector_in>;
+				};
+			};
+		};
+	};

I'd probably like to take the drm patches into drm-next first, then
maybe get a stable
branch from Simon I could use to base the rest on.

Simon, I believe that would be the dt-du-for-v3.19 branch of
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git 

Is it correct ?
