Hi, Here is an preliminary version of the MIPI-DSI support for the Allwinner SoCs. This controller can be found on a number of recent SoCs, such as the A31, A33 or the A64. Given the sparse documentation, there's a number of obscure areas, but the current implementation has been tested with a 4-lanes DSI panel on an A33. In order to support properly the DSI controller, we also had to rework a bit the TCON code to ease the encoders support. The support is a bit rough around the edges at the time, and some artifacts are still shown on the screen for some reasons. Wider testing with different display will hopefully nail those down. It depends for the moment on the clock protection serie sent by Jerome Brunet: http://lists.infradead.org/pipermail/linux-amlogic/2017-June/004059.html Let me know what you think, Maxime Maxime Ripard (18): regmap: mmio: Add function to attach a clock drm/sun4i: Add if statement instead of depends on drm/sun4i: Realign Makefile padding and reorder it drm/sun4i: Remove useless atomic_check drm/sun4i: tcon: remove unused function drm/sun4i: tcon: Don't rely on encoders to enable the TCON drm/sun4i: tcon: Don't rely on encoders to set the TCON mode drm/sun4i: tcon: Add TRI finish interrupt for vblank drm/sun4i: tcon: Adjust dotclock dividers range drm/sun4i: tcon: Move out the tcon0 common setup dt-bindings: display: Add Allwinner MIPI-DSI bindings drm/sun4i: Add Allwinner A31 MIPI-DSI controller support dt-bindings: vendor: Add Huarui Lighting dt-bindings: panel: Add Huarui LHR050H41 panel documentation drm/panel: Add Huarui LHR050H41 panel driver arm: dts: sun8i: a33: Add the DSI-related nodes arm: dts: sun8i: Add BananaPI M2-Magic DTS [DO NOT MERGE] arm: dts: sun8i: bpi-m2m: Add DSI display Documentation/devicetree/bindings/display/panel/huarui,lhr050h41.txt | 19 +- Documentation/devicetree/bindings/display/sunxi/sun6i-dsi.txt | 85 ++++++- Documentation/devicetree/bindings/vendor-prefixes.txt | 1 +- arch/arm/boot/dts/Makefile | 1 +- arch/arm/boot/dts/sun8i-a33.dtsi | 50 ++- arch/arm/boot/dts/sun8i-r16-bananapi-m2m.dts | 360 ++++++++++++++++++++++++- drivers/base/regmap/regmap-mmio.c | 24 ++- drivers/gpu/drm/panel/Kconfig | 9 +- drivers/gpu/drm/panel/Makefile | 1 +- drivers/gpu/drm/panel/panel-huarui-lhr050h41.c | 444 +++++++++++++++++++++++++++++- drivers/gpu/drm/sun4i/Kconfig | 17 +- drivers/gpu/drm/sun4i/Makefile | 31 +- drivers/gpu/drm/sun4i/sun4i_crtc.c | 33 +- drivers/gpu/drm/sun4i/sun4i_dotclock.c | 20 +- drivers/gpu/drm/sun4i/sun4i_hdmi_ddc_clk.c | 1 +- drivers/gpu/drm/sun4i/sun4i_hdmi_enc.c | 15 +- drivers/gpu/drm/sun4i/sun4i_hdmi_tmds_clk.c | 1 +- drivers/gpu/drm/sun4i/sun4i_layer.c | 7 +- drivers/gpu/drm/sun4i/sun4i_rgb.c | 37 +-- drivers/gpu/drm/sun4i/sun4i_tcon.c | 275 ++++++++++++------ drivers/gpu/drm/sun4i/sun4i_tcon.h | 68 ++-- drivers/gpu/drm/sun4i/sun4i_tv.c | 20 +- drivers/gpu/drm/sun4i/sun6i_mipi_dphy.c | 297 +++++++++++++++++++- drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c | 1098 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- drivers/gpu/drm/sun4i/sun6i_mipi_dsi.h | 67 ++++- include/linux/regmap.h | 4 +- 26 files changed, 2783 insertions(+), 202 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/panel/huarui,lhr050h41.txt create mode 100644 Documentation/devicetree/bindings/display/sunxi/sun6i-dsi.txt create mode 100644 arch/arm/boot/dts/sun8i-r16-bananapi-m2m.dts create mode 100644 drivers/gpu/drm/panel/panel-huarui-lhr050h41.c create mode 100644 drivers/gpu/drm/sun4i/sun6i_mipi_dphy.c create mode 100644 drivers/gpu/drm/sun4i/sun6i_mipi_dsi.c create mode 100644 drivers/gpu/drm/sun4i/sun6i_mipi_dsi.h base-commit: d3d855e7c4ffaaa6c2cb221849da65e979d8aa80 -- git-series 0.9.1 -- 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
