Series phy: phy-fsl-imx8-mipi-dphy: Add i.MX8qxp LVDS PHY mode support | expand

Commit Message

Ying Liu April 19, 2022, 1:08 a.m. UTC
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.

I can't currently test this but it still looks good so

Hope this patch won't fall through the cracks.
Can someone please apply it to drm-misc-next? Robert?
