The patch set initial support for Cadence MHDP(HDMI/DP) DRM bridge drivers and Cadence HDP-TX PHY(HDMI/DP) drivers for iMX8MQ. 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 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.
