The patch set initial support Cadence MHDP8501(HDMI/DP) DRM bridge
drivers and Cadence HDP-TX PHY(HDMI/DP) drivers for Freescale i.MX8MQ.

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:
  dt-bindings: display: bridge: Add Cadence MHDP850
  drm: bridge: Cadence: Add MHDP8501 DP/HDMI driver

PHY driver patches:
  dt-bindings: phy: Add Freescale iMX8MQ DP and HDMI PHY
  phy: freescale: Add DisplayPort PHY driver for i.MX8MQ
  phy: freescale: Add HDMI PHY driver for i.MX8MQ

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 <linux/hdmi.h> 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.
