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 git://linuxtv.org/pinchartl/fbdev.git drm/du/adv7511 Cc: devicetree@xxxxxxxxxxxxxxx Cc: Dave Airlie <airlied@xxxxxxxxx> Cc: Lars-Peter Clausen <lars@xxxxxxxxxx> Cc: Simon <horms@xxxxxxxxxxxx> Lars-Peter Clausen (2): drm: Decouple EDID parsing from I2C adapter drm: Add adv7511 encoder driver Laurent Pinchart (7): drm: rcar-du: Remove platform data support drm: rcar-du: Pass the encoder DT node to rcar_du_encoder_init() drm: rcar-du: Replace direct DRM encoder access with cast macro drm: rcar-du: Replace drm_encoder with drm_slave_encoder drm: rcar-du: Add HDMI encoder and connector support video: Add ADV751[13] DT bindings documentation ARM: shmobile: koelsch: Add DU HDMI output support .../devicetree/bindings/video/adi,adv7511.txt | 88 ++ arch/arm/boot/dts/r8a7791-koelsch.dts | 50 +- drivers/gpu/drm/drm_edid.c | 27 +- drivers/gpu/drm/i2c/Kconfig | 6 + drivers/gpu/drm/i2c/Makefile | 2 + drivers/gpu/drm/i2c/adv7511.c | 1010 ++++++++++++++++++++ drivers/gpu/drm/i2c/adv7511.h | 289 ++++++ drivers/gpu/drm/rcar-du/Kconfig | 11 +- drivers/gpu/drm/rcar-du/Makefile | 2 + drivers/gpu/drm/rcar-du/rcar_du_crtc.h | 10 +- drivers/gpu/drm/rcar-du/rcar_du_drv.c | 4 +- drivers/gpu/drm/rcar-du/rcar_du_drv.h | 2 - drivers/gpu/drm/rcar-du/rcar_du_encoder.c | 45 +- drivers/gpu/drm/rcar-du/rcar_du_encoder.h | 23 +- drivers/gpu/drm/rcar-du/rcar_du_hdmicon.c | 118 +++ drivers/gpu/drm/rcar-du/rcar_du_hdmicon.h | 31 + drivers/gpu/drm/rcar-du/rcar_du_hdmienc.c | 151 +++ drivers/gpu/drm/rcar-du/rcar_du_hdmienc.h | 35 + drivers/gpu/drm/rcar-du/rcar_du_kms.c | 53 +- drivers/gpu/drm/rcar-du/rcar_du_lvdscon.c | 31 +- drivers/gpu/drm/rcar-du/rcar_du_lvdscon.h | 2 - drivers/gpu/drm/rcar-du/rcar_du_lvdsenc.h | 1 - drivers/gpu/drm/rcar-du/rcar_du_vgacon.c | 5 +- include/drm/drm_edid.h | 5 + include/linux/platform_data/rcar-du.h | 74 -- 25 files changed, 1894 insertions(+), 181 deletions(-) create mode 100644 Documentation/devicetree/bindings/video/adi,adv7511.txt create mode 100644 drivers/gpu/drm/i2c/adv7511.c create mode 100644 drivers/gpu/drm/i2c/adv7511.h create mode 100644 drivers/gpu/drm/rcar-du/rcar_du_hdmicon.c create mode 100644 drivers/gpu/drm/rcar-du/rcar_du_hdmicon.h create mode 100644 drivers/gpu/drm/rcar-du/rcar_du_hdmienc.c create mode 100644 drivers/gpu/drm/rcar-du/rcar_du_hdmienc.h delete mode 100644 include/linux/platform_data/rcar-du.h -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
