Hi,

This is the v7 series to add 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.

v6->v7:
* Update the year of copyright for patch 2/5.
* Better variable explaination for bits_per_lane_and_dclk_cycle in patch 2/5.
* Use marco instead of magic number for CCM and CA values for patch 5/5.
* Suppress 'checkpatch --strict' warnings for patch 5/5.

v5->v6:
* Rebase the series upon v5.17-rc1.
* Set PHY mode in ->mode_set() instead of ->pre_enable() in the nwl-dsi
  bridge driver in patch 1/5 due to the rebase.
* Drop Guido's R-b tag on patch 1/5 due to the rebase.

v4->v5:
* Align kernel-doc style of include/linux/phy/phy-lvds.h to
  include/linux/phy/phy.h for patch 2/5. (Vinod)
* Trivial tweaks on patch 2/5.
* Drop Robert's R-b tag on patch 2/5.

v3->v4:
* Add all R-b tags received from v3 on relevant patches and respin. (Robert)

v2->v3:
* Improve readability of mixel_dphy_set_mode() in the Mixel PHY driver. (Guido)
* Improve the 'clock-names' property in the PHY dt binding.

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.

The Northwest Logic MIPI DSI host controller embedded in i.MX8qxp
works with a Mixel MIPI DPHY + LVDS PHY combo to support either
a MIPI DSI display or a LVDS display.  So, this patch calls
phy_set_mode() from nwl_dsi_mode_set() to set PHY mode to MIPI DPHY
explicitly.

This patch allows LVDS PHYs to be configured through
the generic functions and through a custom structure
added to the generic union.

The parameters added here are based on common LVDS PHY
implementation practices.  The set of parameters
should cover all potential users.

This patch converts the mixel,mipi-dsi-phy binding to
DT schema format using json-schema.

Comparing to the plain text version, the new binding adds
the 'assigned-clocks', 'assigned-clock-parents' and
'assigned-clock-rates' properites, otherwise 'make dtbs_check'
would complain that there are mis-matches.  Also, the new
binding requires the 'power-domains' property since all potential
SoCs that embed this PHY would provide a power domain for it.
The example of the new binding takes reference to the latest
dphy node in imx8mq.dtsi.

i.MX8qxp SoC embeds a Mixel MIPI DPHY + LVDS PHY combo which supports
either a MIPI DSI display or a LVDS display.  The PHY mode is controlled
by SCU firmware and the driver would call a SCU firmware function to
configure the PHY mode.  The single LVDS PHY has 4 data lanes to support
a LVDS display.  Also, with a master LVDS PHY and a slave LVDS PHY, they
may work together to support a LVDS display with 8 data lanes(usually, dual
LVDS link display).  Note that this patch supports the LVDS PHY mode only
for the i.MX8qxp Mixel combo PHY, i.e., the MIPI DPHY mode is yet to be
supported, so for now error would be returned from ->set_mode() if MIPI
DPHY mode is passed over to it for the combo PHY.
