The patch set compose of DRM bridge drivers and PHY drivers. Both of them need patche #1 and #2 to pass build. DRM bridges driver patches: #1: drm: bridge: Cadence: Creat mhdp helper driver #2: phy: Add HDMI configuration options #3: dt-bindings: display: bridge: Add Cadence MHDP8501 #4: drm: bridge: Cadence: Add MHDP8501 DP/HDMI driver PHY driver patches: #1: drm: bridge: Cadence: Creat mhdp helper driver #2: phy: Add HDMI configuration options #5: dt-bindings: phy: Add Freescale iMX8MQ DP and HDMI PHY #6: phy: freescale: Add DisplayPort PHY driver for i.MX8MQ #7: phy: freescale: Add HDMI PHY driver for i.MX8MQ v10->v11: - rewrite cdns_mhdp_set_firmware_active() in mhdp8546 core driver, use cdns_mhdp_mailbox_send() to replace cdns_mhdp_mailbox_write() same as the other mailbox access functions. - use static for cdns_mhdp_mailbox_write() and cdns_mhdp_mailbox_read() and remove them from EXPORT_SYMBOL_GPL(). - remove MODULE_ALIAS() from mhdp8501 driver. v9->v10: - Create mhdp helper driver to replace macro functions, move all mhdp mailbox access functions and common functions into the helper driver. Patch #1:drm: bridge: Cadence: Creat mhdp helper driver it is totaly different with v9. v8->v9: - Remove compatible string "cdns,mhdp8501" that had removed from dt-bindings file in v8. - Add Dmitry's R-b tag to patch #2 - Add Krzysztof's R-b tag to patch #3 v7->v8: MHDP8501 HDMI/DP: - Correct DT node name to "display-bridge". - Remove "cdns,mhdp8501" from mhdp8501 dt-binding doc. HDMI/DP PHY: - Introduced functions `wait_for_ack` and `wait_for_ack_clear` to handle waiting with acknowledgment bits set and cleared respectively. - Use FIELD_PRE() to set bitfields for both HDMI and DP PHY. v6->v7: MHDP8501 HDMI/DP: - Combine HDMI and DP driver into one mhdp8501 driver. Use the connector type to load the corresponding functions. - Remove connector init functions. - Add in phy_hdmi.h to reuse ‘enum hdmi_colorspace’. HDMI/DP PHY: - Lowercase hex values - Fix parameters indent issue on some functions - Replace ‘udelay’ with ‘usleep_range’ v5->v6: HDMI/DP bridge driver - 8501 is the part number of Cadence MHDP on i.MX8MQ. Use MHDP8501 to name hdmi/dp drivers and files. - Add compatible "fsl,imx8mq-mhdp8501-dp" for i.MX8MQ DP driver - Add compatible "fsl,imx8mq-mhdp8501-hdmi" for i.MX8MQ HDMI driver - Combine HDMI and DP dt-bindings into one file cdns,mhdp8501.yaml - Fix HDMI scrambling is not enable issue when driver working in 4Kp60 mode. - Add HDMI/DP PHY API mailbox protect. HDMI/DP PHY driver: - Rename DP and HDMI PHY files and move to folder phy/freescale/ - Remove properties num_lanes and link_rate from DP PHY driver. - Combine HDMI and DP dt-bindings into one file fsl,imx8mq-dp-hdmi-phy.yaml - Update compatible string to "fsl,imx8mq-dp-phy". - Update compatible string to "fsl,imx8mq-hdmi-phy". v4->v5: - Drop "clk" suffix in clock name. - Add output port property in the example of hdmi/dp. v3->v4: dt-bindings: - Correct dt-bindings coding style and address review comments. - Add apb_clk description. - Add output port for HDMI/DP connector PHY: - Alphabetically sorted in Kconfig and Makefile for DP and HDMI PHY - Remove unused registers define from HDMI and DP PHY drivers. - More description in phy_hdmi.h. - Add apb_clk to HDMI and DP phy driver. HDMI/DP: - Use get_unaligned_le32() to replace hardcode type conversion in HDMI AVI infoframe data fill function. - Add mailbox mutex lock in HDMI/DP driver for phy functions to reslove race conditions between HDMI/DP and PHY drivers. - Add apb_clk to both HDMI and DP driver. - Rename some function names and add prefix with "cdns_hdmi/cdns_dp". - Remove bpc 12 and 16 optional that not supported. 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.
