Hi all, The Samsung Exynos eDP controller and Rockchip RK3288 eDP controller share the same IP, so a lot of parts can be re-used. I split the common code into bridge directory, then rk3288 and exynos only need to keep some platform code. Cause I can't find the exact IP name of exynos dp controller, so I decide to name dp core driver with "analogix" which I find in rk3288 eDP TRM :) This time I create this version on linux-next branch (tag is next-20150918), and also applied this version to Heiko github eDP branch to verify the function. (https://github.com/mmind/linux-rockchip/tree/tmp/edp-with-veyron) Glad to say my chromebook "cnm,n116bgeea2" eDP panel just lighted rightly on Heiko branch. And after back port this series to chromeos-3.14 tree, my rk3288 SDK board still can light my 2K DisplayPort monitor. So this time would be okay on mainline kernel and chromeos-3.14 tree. ;) Due to no Exynos board in my side, so I haven't verified the eDP function on samsung platform, I only ensure that there are no obvious compiled error. Any help would be greatly appreciated. :) Thanks, - Yakir Changes in v5: - Correct the check condition of gpio_is_valid when driver try to get the "hpd-gpios" DT propery. (Heiko) - Move the platform attach callback in the front of core driver bridge attch function. Cause once platform failed at attach, core driver should still failed, so no need to init connector before platform attached (Krzysztof) - Keep code style no changes with the previous exynos_dp_code.c in this patch, and update commit message about the new export symbol (Krzysztof) - Gather the device type patch (v4 11/16) into this one. (Krzysztof) - leave out the connector registration to analogix platform driver. (Thierry) - Resequence this patch after analogix_dp driver have been split from exynos_dp code, and rephrase reasonable commit message, and remove some controversial style (Krzysztof) - analogix_dp_write_byte_to_dpcd( - dp, DP_TEST_RESPONSE, + analogix_dp_write_byte_to_dpcd(dp, + DP_TEST_RESPONSE, DP_TEST_EDID_CHECKSUM_WRITE); - Switch video timing type to "u32", so driver could use "of_property_read_u32" to get the backword timing values. Krzysztof suggest me that driver could use the "of_property_read_bool" to get backword timing values, but that interfacs would modify the original drm_display_mode timing directly (whether those properties exists or not). - Correct the misspell in commit message. (Krzysztof) - Remove the empty line at the end of document, and correct the endpoint numbers in the example DT node, and remove the regulator iomux setting in driver code while using the pinctl in devicetree instead. (Heiko) - Add device type declared, cause the previous "platform device type support (v4 11/16)" already merge into (v5 02/14). - Implement connector registration code. (Thierry) - Split binding doc's from driver changes. (Rob) - Add eDP hotplug pinctrl property. (Heiko) - Remove "reg" DT property, cause driver could poweron/poweroff phy via the exist "grf" syscon already. And rename the example DT node from "edp_phy: phy@ff770274" to "edp_phy: edp-phy" directly. (Heiko) - Add deivce_node at the front of driver, update phy_ops type from "static struct" to "static const struct". And correct the input paramters of devm_phy_create() interfaces. (Heiko) - Split binding doc's from driver changes. (Rob) - Update the rockchip,grf explain in document, and correct the clock required elemets in document. (Rob & Heiko) - Fix compiled error (Heiko) - Using the connector display info message to configure eDP driver input video mode, but hard code CRTC video output mode to RGBaaa. Changes in v4: - Update "analogix,hpd-gpios" to "hpd-gpios" DT propery. (Rob) - Rename "analogix_dp-exynos.c" file name to "exynos_dp.c" (Jingoo) - Create a separate folder for analogix code in bridge/ (Archit) - Update commit message more readable. (Jingoo) - Adjust the order from 05 to 04 - Provide backword compatibility with samsung. (Krzysztof) - Split all DTS changes, and provide backward compatibility. Mark old properties as deprecated but still support them. (Krzysztof) - Update "analogix,hpd-gpio" to "hpd-gpios" prop name. (Rob) - Deprecated some properties which could parsed from Edid/Mode/DPCD. (Thierry) "analogix,color-space" & "analogix,color-depth" & "analogix,link-rate" & "analogix,lane-count" & "analogix,ycbcr-coeff" & "analogix,dynamic-range" & "vsync-active-high" & "hsync-active-high" & "interlaces" - Separate all DTS changes to a separate patch. (Krzysztof) - Remove some deprecated DT properties in rockchip dp document. - Add commit message, and remove the redundant rockchip_dp_phy_init() function, move those code to probe() method. And remove driver .owner number. (Kishon) - Seprate the link-rate and lane-count limit out with the device_type flag. (Thierry) - Take Jingoo suggest, add commit messages. - Call drm_panel_prepare() in .get_modes function, ensure panel should power on before driver try to read edid message. Changes in v3: - Move exynos's video_timing code to analogix_dp-exynos platform driver, add get_modes method to struct analogix_dp_plat_data. (Thierry) - Rename some "samsung*" dts propery to "analogix*". (Heiko) - The link_rate and lane_count shouldn't config to the DT property value directly, but we can take those as hardware limite. For example, RK3288 only support 4 physical lanes of 2.7/1.62 Gbps/lane, so DT property would like "link-rate = 0x0a" "lane-count = 4". (Thierry) - Dynamic parse video timing info from struct drm_display_mode and struct drm_display_info. (Thierry) - Add devicetree binding documents. (Heiko) - Remove sync pol & colorimetry properies from the new analogix dp driver devicetree binding. (Thierry) - Update the exist exynos dtsi file with the latest DP DT properies. - Leave "sclk_edp_24m" to rockchip dp phy driver which name to "24m", and leave "sclk_edp" to analogix dp core driver which name to "dp", and leave "pclk_edp" to rockchip dp platform driver which name to "pclk". (Thierry & Heiko) - Add devicetree binding document. (Heiko) - Remove "rockchip,panel" DT property, take use of remote point to get panel node. (Heiko) - Add the new function point dp_platdata->get_modes() init. - Suggest, add rockchip dp phy driver, collect the phy clocks and power control. (Heiko) - Add "analogix,need-force-hpd" to indicate whether driver need foce hpd when hpd detect failed. - move dp hpd detect to connector detect function. - Add edid modes parse support Changes in v2: - Keep author name list no changed (Jingoo) - Remove new copyright (Jingoo) - Fix compiled failed due to analogix_dp_device misspell - Improved commit message more readable, and avoid using some uncommon style like bellow: (Joe Preches) - retval = exynos_dp_read_bytes_from_i2c(... ...); + retval = + exynos_dp_read_bytes_from_i2c(......); - Get panel node with remote-endpoint method, and create devicetree binding for driver. (Heiko) - Remove the clock enable/disbale with "sclk_edp" & "sclk_edp_24m", leave those clock to rockchip dp phy driver. - Fix compile failed dut to phy_pd_addr variable misspell error Mark Yao (1): drm: rockchip: vop: add bpc and color mode setting Yakir Yang (16): drm: exynos: dp: convert to drm bridge mode drm: bridge: analogix/dp: split exynos dp driver to bridge directory drm: bridge: analogix/dp: fix some obvious code style drm: bridge: analogix/dp: remove duplicate configuration of link rate and link count drm: bridge: analogix/dp: dynamic parse sync_pol & interlace & dynamic_range Documentation: drm/bridge: add document for analogix_dp ARM: dts: exynos/dp: remove some properties that deprecated by analogix_dp driver drm: rockchip: dp: add rockchip platform dp driver Documentation: drm/bridge: add document for analogix_dp phy: Add driver for rockchip Display Port PHY Documentation: phy: add document for rockchip dp phy drm: bridge: analogix/dp: add some rk3288 special registers setting drm: bridge: analogix/dp: add max link rate and lane count limit for RK3288 drm: bridge: analogix/dp: try force hpd after plug in lookup failed drm: bridge: analogix/dp: move hpd detect to connector detect function drm: bridge: analogix/dp: add edid modes parse in get_modes method .../devicetree/bindings/drm/bridge/analogix_dp.txt | 52 + .../devicetree/bindings/phy/rockchip-dp-phy.txt | 22 + .../bindings/video/analogix_dp-rockchip.txt | 91 ++ .../devicetree/bindings/video/exynos_dp.txt | 64 +- arch/arm/boot/dts/exynos5250-arndale.dts | 2 - arch/arm/boot/dts/exynos5250-smdk5250.dts | 2 - arch/arm/boot/dts/exynos5250-snow.dts | 4 +- arch/arm/boot/dts/exynos5250-spring.dts | 4 +- arch/arm/boot/dts/exynos5420-peach-pit.dts | 4 +- arch/arm/boot/dts/exynos5420-smdk5420.dts | 2 - arch/arm/boot/dts/exynos5800-peach-pi.dts | 4 +- drivers/gpu/drm/bridge/Kconfig | 2 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/analogix/Kconfig | 4 + drivers/gpu/drm/bridge/analogix/Makefile | 1 + drivers/gpu/drm/bridge/analogix/analogix_dp_core.c | 1372 +++++++++++++++++++ drivers/gpu/drm/bridge/analogix/analogix_dp_core.h | 286 ++++ drivers/gpu/drm/bridge/analogix/analogix_dp_reg.c | 1294 ++++++++++++++++++ .../analogix/analogix_dp_reg.h} | 270 ++-- drivers/gpu/drm/exynos/Kconfig | 3 +- drivers/gpu/drm/exynos/Makefile | 2 +- drivers/gpu/drm/exynos/exynos_dp.c | 366 +++++ drivers/gpu/drm/exynos/exynos_dp_core.c | 1427 -------------------- drivers/gpu/drm/exynos/exynos_dp_core.h | 281 ---- drivers/gpu/drm/exynos/exynos_dp_reg.c | 1263 ----------------- drivers/gpu/drm/rockchip/Kconfig | 9 + drivers/gpu/drm/rockchip/Makefile | 1 + drivers/gpu/drm/rockchip/analogix_dp-rockchip.c | 457 +++++++ drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 2 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.h | 2 +- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 32 +- drivers/phy/Kconfig | 7 + drivers/phy/Makefile | 1 + drivers/phy/phy-rockchip-dp.c | 151 +++ include/drm/bridge/analogix_dp.h | 42 + 35 files changed, 4360 insertions(+), 3167 deletions(-) create mode 100644 Documentation/devicetree/bindings/drm/bridge/analogix_dp.txt create mode 100644 Documentation/devicetree/bindings/phy/rockchip-dp-phy.txt create mode 100644 Documentation/devicetree/bindings/video/analogix_dp-rockchip.txt create mode 100644 drivers/gpu/drm/bridge/analogix/Kconfig create mode 100644 drivers/gpu/drm/bridge/analogix/Makefile create mode 100644 drivers/gpu/drm/bridge/analogix/analogix_dp_core.c create mode 100644 drivers/gpu/drm/bridge/analogix/analogix_dp_core.h create mode 100644 drivers/gpu/drm/bridge/analogix/analogix_dp_reg.c rename drivers/gpu/drm/{exynos/exynos_dp_reg.h => bridge/analogix/analogix_dp_reg.h} (62%) create mode 100644 drivers/gpu/drm/exynos/exynos_dp.c delete mode 100644 drivers/gpu/drm/exynos/exynos_dp_core.c delete mode 100644 drivers/gpu/drm/exynos/exynos_dp_core.h delete mode 100644 drivers/gpu/drm/exynos/exynos_dp_reg.c create mode 100644 drivers/gpu/drm/rockchip/analogix_dp-rockchip.c create mode 100644 drivers/phy/phy-rockchip-dp.c create mode 100644 include/drm/bridge/analogix_dp.h -- 1.9.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
