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

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.

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
