The patch set initial support for Cadence MHDP(HDMI/DP) DRM bridge drivers and Cadence HDP-TX PHY(HDMI/DP) drivers for iMX8MQ. v2->v3: Address comments for dt-bindings files. - Correct dts-bindings file names Rename phy-cadence-hdptx-dp.yaml to cdns,mhdp-imx8mq-dp.yaml Rename phy-cadence-hdptx-hdmi.yaml to cdns,mhdp-imx8mq-hdmi.yaml - Drop redundant words and descriptions. - Correct hdmi/dp node name. v2 is a completely different version compared to v1. Previous v1 can be available here [1]. v1->v2: - Reuse Cadence mailbox access functions from mhdp8546 instead of rockchip DP. - Mailbox access functions be convert to marco functions that will be referenced by HDP-TX PHY(HDMI/DP) driver too. - Plain bridge instead of component driver. - Standalone Cadence HDP-TX PHY(HDMI/DP) driver. - Audio driver are removed from the patch set, it will be add in another patch set later. The patch set compose of DRM bridge drivers and PHY drivers. Both of them need the followed two patches to pass build. drm: bridge: cadence: convert mailbox functions to macro functions phy: Add HDMI configuration options DRM bridges driver patches: dts-bingings: display: bridge: Add MHDP HDMI bindings for i.MX8MQ drm: bridge: cadence: Add MHDP DP driver for i.MX8MQ dts-bindings: display: bridge: Add MHDP DP bindings for i.MX8MQ drm: bridge: cadence: Add MHDP HDMI driver for i.MX8MQ PHY driver patches: dts-bindings: phy: Add Cadence HDP-TX DP PHY bindings phy: cadence: Add driver for HDP-TX DisplyPort PHY dts-bindings: phy: Add Cadence HDP-TX HDMI PHY bindings phy: cadence: Add driver for HDP-TX HDMI PHY [1] https://patchwork.kernel.org/project/linux-rockchip/cover/cover.1590982881.git.Sandor.yu@xxxxxxx/ Sandor Yu (10): drm: bridge: cadence: convert mailbox functions to macro functions dt-bindings: display: bridge: Add MHDP HDMI for i.MX8MQ drm: bridge: cadence: Add MHDP DP driver for i.MX8MQ phy: Add HDMI configuration options dt-bindings: display: bridge: Add MHDP DP for i.MX8MQ drm: bridge: cadence: Add MHDP HDMI driver for i.MX8MQ dt-bindings: phy: Add Cadence HDP-TX DP PHY phy: cadence: Add driver for HDP-TX DisplyPort PHY dt-bindings: phy: Add Cadence HDP-TX HDMI PHY phy: cadence: Add driver for HDP-TX HDMI PHY .../display/bridge/cdns,mhdp-imx8mq-dp.yaml | 59 + .../display/bridge/cdns,mhdp-imx8mq-hdmi.yaml | 59 + .../bindings/phy/cdns,hdptx-dp-phy.yaml | 66 + .../bindings/phy/cdns,hdptx-hdmi-phy.yaml | 50 + drivers/gpu/drm/bridge/cadence/Kconfig | 25 + drivers/gpu/drm/bridge/cadence/Makefile | 3 + drivers/gpu/drm/bridge/cadence/cdns-dp-core.c | 1070 +++++++++++++++++ .../gpu/drm/bridge/cadence/cdns-hdmi-core.c | 1038 ++++++++++++++++ .../gpu/drm/bridge/cadence/cdns-mhdp-common.h | 402 +++++++ .../drm/bridge/cadence/cdns-mhdp8546-core.c | 197 +-- .../drm/bridge/cadence/cdns-mhdp8546-core.h | 1 - drivers/phy/cadence/Kconfig | 16 + drivers/phy/cadence/Makefile | 2 + drivers/phy/cadence/phy-cadence-hdptx-dp.c | 774 ++++++++++++ drivers/phy/cadence/phy-cadence-hdptx-hdmi.c | 948 +++++++++++++++ include/drm/bridge/cdns-mhdp-mailbox.h | 240 ++++ include/linux/phy/phy-hdmi.h | 33 + include/linux/phy/phy.h | 7 +- 18 files changed, 4793 insertions(+), 197 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/bridge/cdns,mhdp-imx8mq-dp.yaml create mode 100644 Documentation/devicetree/bindings/display/bridge/cdns,mhdp-imx8mq-hdmi.yaml create mode 100644 Documentation/devicetree/bindings/phy/cdns,hdptx-dp-phy.yaml create mode 100644 Documentation/devicetree/bindings/phy/cdns,hdptx-hdmi-phy.yaml create mode 100644 drivers/gpu/drm/bridge/cadence/cdns-dp-core.c create mode 100644 drivers/gpu/drm/bridge/cadence/cdns-hdmi-core.c create mode 100644 drivers/gpu/drm/bridge/cadence/cdns-mhdp-common.h create mode 100644 drivers/phy/cadence/phy-cadence-hdptx-dp.c create mode 100644 drivers/phy/cadence/phy-cadence-hdptx-hdmi.c create mode 100644 include/drm/bridge/cdns-mhdp-mailbox.h create mode 100644 include/linux/phy/phy-hdmi.h -- 2.34.1
