Subject[PATCH v6 resend 1/5] drm/bridge: nwl-dsi: Set PHY mode in nwl_dsi_mode_set()
Date
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.

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 due to the rebase.
* Drop Guido's R-b tag due to the rebase.
* Resend with Andrzej's and Jernej's mail addressed updated.

v4->v5:
* No change.

v3->v4:
* No change.

v2->v3:
* No change.

v1->v2:
* Add Guido's R-b tag.
