    Subject[PATCH v4 00/10] Initial support for Cadence MHDP(HDMI/DP) for i.MX8MQ
    Date
    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.
