* [PATCH v6 0/5] drm: Add Support for Passive RGB to VGA bridges @ 2016-10-06 7:57 ` Maxime Ripard 0 siblings, 0 replies; 16+ messages in thread From: Maxime Ripard @ 2016-10-06 7:57 UTC (permalink / raw) To: Rob Herring, Daniel Vetter, David Airlie, Archit Taneja Cc: devicetree, dri-devel, Chen-Yu Tsai, Maxime Ripard, linux-arm-kernel Hi, This serie is about adding support for the RGB to VGA bridge found in the A13-Olinuxino and the CHIP VGA adapter. Both these boards rely on an entirely passive bridge made out of resitor ladders that do not require any initialisation. The only thing needed is to get the timings from the screen if available (and if not, fall back on XGA standards), set up the display pipeline to output on the RGB bus with the proper timings, and you're done. This serie also fixes a bunch of bugs uncovered when trying to increase the resolution, and hence the pixel clock, of our pipeline. It also fixes a few bugs in the DRM driver itself that went unnoticed before. Let me know what you think, Maxime Changes from v5: - Renamed to simple-vga-dac Changes from v4: - Removed unused functions Changes from v3: - Depends on OF in Kconfig - Fixed typos in the driver comments - Removed the mention of a "passive" bridge in the bindings doc - Made the strcuture const - Removed the nops and best_encoders implementations - Removed the call to drm_bridge_enable in the sun4i driver Changes from v2: - Changed the compatible as suggested - Rebased on top 4.8 Changes from v1: - Switch to using a vga-connector - Use drm_encoder bridge pointer instead of doing our own - Report the connector status as unknown instead of connected by default, and as connected only if we can retrieve the EDID. - Switch to of_i2c_get_adapter by node, and put the reference when done - Rebased on linux-next Maxime Ripard (5): drm/sun4i: rgb: Remove the bridge enable/disable functions drm/bridge: Add RGB to VGA bridge support ARM: sun5i: a13-olinuxino: Enable VGA bridge ARM: multi_v7: enable VGA bridge ARM: sunxi: Enable VGA bridge .../bindings/display/bridge/rgb-to-vga-bridge.txt | 48 +++++ arch/arm/boot/dts/sun5i-a13-olinuxino.dts | 54 +++++ arch/arm/configs/multi_v7_defconfig | 1 + arch/arm/configs/sunxi_defconfig | 1 + drivers/gpu/drm/bridge/Kconfig | 7 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/rgb-to-vga.c | 229 +++++++++++++++++++++ drivers/gpu/drm/sun4i/sun4i_rgb.c | 6 - 8 files changed, 341 insertions(+), 6 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/bridge/rgb-to-vga-bridge.txt create mode 100644 drivers/gpu/drm/bridge/rgb-to-vga.c -- 2.9.3 Maxime Ripard (5): drm/sun4i: rgb: Remove the bridge enable/disable functions drm/bridge: Add RGB to VGA bridge support ARM: sun5i: a13-olinuxino: Enable VGA bridge ARM: multi_v7: enable VGA bridge ARM: sunxi: Enable VGA bridge Documentation/devicetree/bindings/display/bridge/simple-vga-dac.txt | 48 +++++++++++++++- arch/arm/boot/dts/sun5i-a13-olinuxino.dts | 54 +++++++++++++++++- arch/arm/configs/multi_v7_defconfig | 1 +- arch/arm/configs/sunxi_defconfig | 1 +- drivers/gpu/drm/bridge/Kconfig | 7 ++- drivers/gpu/drm/bridge/Makefile | 1 +- drivers/gpu/drm/bridge/simple-vga-dac.c | 229 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- drivers/gpu/drm/sun4i/sun4i_rgb.c | 6 +-- 8 files changed, 341 insertions(+), 6 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/bridge/simple-vga-dac.txt create mode 100644 drivers/gpu/drm/bridge/simple-vga-dac.c -- git-series 0.8.10 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 16+ messages in thread

* [PATCH v6 2/5] drm/bridge: Add RGB to VGA bridge support @ 2016-10-06 7:57 ` Maxime Ripard 0 siblings, 0 replies; 16+ messages in thread From: Maxime Ripard @ 2016-10-06 7:57 UTC (permalink / raw) To: linux-arm-kernel Some boards have an entirely passive RGB to VGA bridge, based on either DACs or resistor ladders. Those might or might not have an i2c bus routed to the VGA connector in order to access the screen EDIDs. Add a bridge that doesn't do anything but expose the modes available on the screen, either based on the EDIDs if available, or based on the XGA standards.
