Subject: [PATCH v4 00/10] Initial support for Cadence MHDP(HDMI/DP) for i.MX8MQ
Date: Mon, 21 Nov 2022 15:23:50 +0800	[thread overview]
Message-ID: <cover.1669013346.git.Sandor.yu@nxp.com> (raw)

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.
