We found Freescale imx6 and Rockchip rk3288 and Ingenic JZ4780 (Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly differences, such as phy pll configuration, register width(imx hdmi register is one byte, but rk3288 is 4 bytes width and can only be accessed by word), 4K support(imx6 doesn't support 4k, but rk3288 does), and HDMI2.0 support. To reuse the imx-hdmi driver, we make this patch set: (1): fix some CodingStyle warning to make checkpatch happy (2): convert imx-hdmi to drm_bridge (3): split platform specific code (4): move imx-hdmi to bridge/dw_hdmi (5): extend dw_hdmi.c to support rk3288 hdmi (6): add rockchip rk3288 platform specific code dw_hdmi-rockchip.c Changes in v18: - remove a multiple blank lines in imx-hdmi.c - fix a checkpatch warning in imx-hdmi_pltfm.c - add port bindings - correct some spelling mistakes in dw_hdmi bindings doc - correct some spelling mistakes in dw_hdmi-rockchip bindings doc Changes in v17: - remove platform device stuff, adviced by Russell King - remove prompt message of dw_hdmi, adviced by Russel King - parse resource and irq in platform driver Changes in v16: - use the common binding for the clocks - describe ddc-i2c-bus as optional - add common clocks bindings - modify clocks bindings - descrbie ddc-i2c-bus as optional Changes in v15: - add prefix dw_hdmi/DW_HDMI for public used dw_hdmi structs adviced by Philipp Zabel - remove THIS_MODULE in platform driver - remove unio of the multi-byte register access, adviced by Philipp Zabel - remove THIS_MODULE in platform driver Changes in v14: - add defer probing, adviced by Philipp Zabel - remove drm_connector_register, because imx-drm core has registered connector Changes in v13: - patch against drm-next - split platform specific phy configuration - split phy configuration from patch#4 Changes in v12: - refactor of_node_put(ddc_node) - squash patch <convert dw_hdmi to drm_bridge> - add comment for the depend on patch Changes in v11: - squash patch <split some phy configuration to platform driver> Changes in v10: - split generic dw_hdmi.c improvements from patch#11 (add rk3288 support) - add more display mode support mpll configuration for rk3288 Changes in v9: - move some phy configuration to platform driver Changes in v8: - correct some spelling mistake - modify ddc-i2c-bus and interrupt description - Add documentation for rockchip dw hdmi Changes in v7: - remove unused variables from structure dw_hdmi - remove a wrong modification - add copyrights for dw_hdmi-imx.c Changes in v6: - rearrange the patch order - refactor register access without reg_shift Changes in v5: - refactor reg-io-width Changes in v4: - fix checkpatch CHECK - defer probe ddc i2c adapter Changes in v3: - split multi-register access to one indepent patch Andy Yan (12): drm: imx: imx-hdmi: make checkpatch happy drm: imx: imx-hdmi: return defer if can't get ddc i2c adapter drm: imx: imx-hdmi: convert imx-hdmi to drm_bridge mode drm: imx: imx-hdmi: split phy configuration to platform driver drm: imx: imx-hdmi: move imx-hdmi to bridge/dw_hdmi dt-bindings: add document for dw_hdmi drm: bridge/dw_hdmi: add support for multi-byte register width access drm: bridge/dw_hdmi: add mode_valid support drm: bridge/dw_hdmi: clear i2cmphy_stat0 reg in hdmi_phy_wait_i2c_done drm: bridge/dw_hdmi: add function dw_hdmi_phy_enable_spare dt-bindings: Add documentation for rockchip dw hdmi drm: bridge/dw_hdmi: add rockchip rk3288 support .../devicetree/bindings/drm/bridge/dw_hdmi.txt | 50 ++ .../devicetree/bindings/video/dw_hdmi-rockchip.txt | 46 ++ drivers/gpu/drm/bridge/Kconfig | 5 + drivers/gpu/drm/bridge/Makefile | 1 + .../gpu/drm/{imx/imx-hdmi.c => bridge/dw_hdmi.c} | 717 ++++++++++----------- .../gpu/drm/{imx/imx-hdmi.h => bridge/dw_hdmi.h} | 4 +- drivers/gpu/drm/imx/Kconfig | 1 + drivers/gpu/drm/imx/Makefile | 2 +- drivers/gpu/drm/imx/dw_hdmi-imx.c | 258 ++++++++ drivers/gpu/drm/rockchip/Kconfig | 10 + drivers/gpu/drm/rockchip/Makefile | 2 + drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 341 ++++++++++ include/drm/bridge/dw_hdmi.h | 61 ++ 13 files changed, 1111 insertions(+), 387 deletions(-) create mode 100644 Documentation/devicetree/bindings/drm/bridge/dw_hdmi.txt create mode 100644 Documentation/devicetree/bindings/video/dw_hdmi-rockchip.txt rename drivers/gpu/drm/{imx/imx-hdmi.c => bridge/dw_hdmi.c} (72%) rename drivers/gpu/drm/{imx/imx-hdmi.h => bridge/dw_hdmi.h} (99%) create mode 100644 drivers/gpu/drm/imx/dw_hdmi-imx.c create mode 100644 drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c create mode 100644 include/drm/bridge/dw_hdmi.h -- 1.9.1 -- 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
