Depending on the SoC, the number of instances of the controller will change (2 instances of each in the A10, only one in the A13, for example), and the output availables will change too (HDMI, composite, VGA on the A20, none of them on the A13). On most featured SoCs, it looks like that: +--------------------------------------------+ | RAM | +--------------------------------------------+ | | | | v | | v +----------------+ | | +----------------+ | Frontend | | | | Frontend | +----------------+ | | +----------------+ | | | | v | | v +----------------+ | | +----------------+ | Backend |<+ +>| Backend | +----------------+ +----------------+ | | v v +----------------+ +----------------+---> LVDS | TCON | | TCON |---> RGB +----------------+ +----------------+ | +---+ +---+ | | | | | v v v v +------------+ +------------+ +------------+---> VGA | TV Encoder | | HDMI | | TV Encoder |---> Composite +------------+ +------------+ +------------+ The current code only assumes that there is a single instance of all the controllers. It also supports only the RGB and Composite interfaces. Let me know what you think, Maxime Changes from v1: - Rebased on top of 4.4 - Merged the clock drivers for the display and TCON channel 0 clocks - Replaced the container_of calls in the display reset clocks to an inline function - Checked the return code of of_clk_parent_fill in the clocks drivers - Checked the return code of of_clk_add_provider in the tcon-ch1 and PLL3 clocks - Added missing clocks headers - Created a composite clock unregister function - Moved the binding documentation to Documentation/devicetree/bindings/display - Added the clocks binding documentation - Added the Olimex vendor to the list of DT vendors - Moved to the OF graph representation and the component framework - Moved the reset cells count check into the reset framework to avoid duplicating the code in every xlate implementation. - Made the reset_ops const - Reworked the DRM cmdline mode parsing code to allow named mode - Fixed the TV mode lookup when the mode name is not present (for example because it was given by the userspace) - Made the driver outputs optional (to avoid crashing when a board doesn't have either a panel or a composite output enabled) - Added multiple plane support with transparency - Moved the backend registers writes commit in the CRTC atomic_flush callback - Removed the load / unload functions - Removed the enabled booleans in my private structure and removed the implicit call to disable_unused_functions in the DRM core to push it in the drivers. - Fixed a few bitmasks on some bitfields definition - Fixed the RGB connector mode validation that was not testing the right values Matthias Brugger (1): clk: Add regmap support Maxime Ripard (25): reset: Move DT cell size check to the core reset: Make reset_control_ops const clk: composite: Add unregister function clk: sunxi: Add display and TCON0 clocks driver clk: sunxi: Add PLL3 clock clk: sunxi: Add TCON channel1 clock clk: sun5i: add DRAM gates ARM: sun5i: dt: Add pll3 and pll7 clocks ARM: sun5i: a13: Add display and TCON clocks ARM: sun5i: Add DRAM gates ARM: sun5i: Add TV encoder gate to the DTSI drm/fb_cma_helper: Remove implicit call to disable_unused_functions drm/modes: Rewrite the command line parser drm/modes: Support modes names on the command line drm: Add Allwinner A10 Display Engine support drm: sun4i: Add DT bindings documentation drm: sun4i: Add RGB output drm: sun4i: Add composite output drm: sun4i: tv: Add PAL output standard drm: sun4i: tv: Add NTSC output standard ARM: sun5i: r8: Add display blocks to the DTSI ARM: sun5i: chip: Enable the TV Encoder devicetree: Add olimex vendor prefix drm/panel: simple: Add timings for the Olimex LCD-OLinuXino-4.3TS DO NOT MERGE: ARM: sun5i: chip: Enable the LCD panel Documentation/devicetree/bindings/clock/sunxi.txt | 5 + .../display/panel/olimex,lcd-olinuxino-43-ts.txt | 7 + .../bindings/display/sunxi/sun4i-drm.txt | 228 +++++++ .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/boot/dts/sun5i-a10s.dtsi | 7 +- arch/arm/boot/dts/sun5i-a13.dtsi | 46 +- arch/arm/boot/dts/sun5i-r8-chip.dts | 17 + arch/arm/boot/dts/sun5i-r8.dtsi | 139 ++++- arch/arm/boot/dts/sun5i.dtsi | 62 ++ drivers/clk/Makefile | 1 + drivers/clk/clk-composite.c | 15 + drivers/clk/clk-divider.c | 68 ++- drivers/clk/clk-gate.c | 54 +- drivers/clk/clk-io.c | 48 ++ drivers/clk/clk-io.h | 22 + drivers/clk/clk-mux.c | 94 ++- drivers/clk/sunxi/Makefile | 3 + drivers/clk/sunxi/clk-simple-gates.c | 2 + drivers/clk/sunxi/clk-sun4i-display.c | 241 ++++++++ drivers/clk/sunxi/clk-sun4i-pll3.c | 90 +++ drivers/clk/sunxi/clk-sun4i-tcon-ch1.c | 154 +++++ drivers/gpu/drm/Kconfig | 2 + drivers/gpu/drm/Makefile | 3 +- drivers/gpu/drm/drm_crtc.c | 3 +- drivers/gpu/drm/drm_fb_cma_helper.c | 3 -
