Hi,

This series adds i.MX8qxp LVDS PHY mode support for the Mixel PHY in the
Freescale i.MX8qxp SoC.

The Mixel PHY is MIPI DPHY + LVDS PHY combo, which can works in either
MIPI DPHY mode or LVDS PHY mode.  The PHY mode is controlled by i.MX8qxp
SCU firmware.  The PHY driver would call a SCU function to configure the
mode.

The PHY driver is already supporting the Mixel MIPI DPHY in i.MX8mq SoC,
where it appears to be a single MIPI DPHY.


Patch 1/5 sets PHY mode in the Northwest Logic MIPI DSI host controller
bridge driver, since i.MX8qxp SoC embeds this controller IP to support
MIPI DSI displays together with the Mixel PHY.

Patch 2/5 allows LVDS PHYs to be configured through the generic PHY functions
and through a custom structure added to the generic PHY configuration union.

Patch 3/5 converts mixel,mipi-dsi-phy plain text dt binding to json-schema.

Patch 4/5 adds dt binding support for the Mixel combo PHY in i.MX8qxp SoC.

Patch 5/5 adds the i.MX8qxp LVDS PHY mode support in the Mixel PHY driver.


Welcome comments, thanks.

v1->v2:
* Convert mixel,mipi-dsi-phy plain text dt binding to json-schema. (Guido)
* Print invalid PHY mode in dmesg from the Mixel PHY driver. (Guido)
* Add Guido's R-b tag on the patch for the nwl-dsi drm bridge driver.
