[PATCH v3 0/9] drm/bridge: imx: Add i.MX93 MIPI DSI support

[Liu Ying]

Hi,

This series aims to add MIPI DSI support for Freescale i.MX93 SoC.

There is a Synopsys DesignWare MIPI DSI host controller and a Synopsys
Designware MIPI DPHY embedded in i.MX93.  Some configurations and
extensions to them are controlled by i.MX93 media blk-ctrl.

Add a DRM bridge for i.MX93 MIPI DSI by using existing DW MIPI DSI
bridge helpers and implementing i.MX93 MIPI DSI specific extensions.

Note that since this series touches the dw-mipi-dsi driver, tests are
needed to be done for meson, rockchip and stm.

Patch 1 ~ 7 do preparation work for adding i.MX93 MIPI DSI DRM bridge driver.

Patch 8 adds DT-binding documentation for i.MX93 MIPI DSI.

Patch 9 adds i.MX93 MIPI DSI DRM bridge.

v2->v3:
* Add Neil's R-b tags from v1 on patch 5/6/7.
* Select GENERIC_PHY to fix Kconfig warning for GENERIC_PHY_MIPI_DPHY
  dependency in patch 9.
* Cc stm and rockchip folks.

v1->v2:
* Add Rob's R-b tag on patch 8.
* Use dev_err_probe() to replace DRM_DEV_ERROR() in patch 9.  (Sam and Alexander)
* Use dev_*() to replace DRM_*() in patch 9.  (Sam)
* Fix build for arm architecture in patch 9.
  (Reported-by: kernel test robot <lkp at intel.com>)
* Improve error messages for imx93_dsi_phy_init() in patch 9.
