5.19: mipi-dphy bug
https://lore.kernel.org/linux-arm-kernel/20220419010852.452169-6-victor.liu@nxp.com/ ( 3fbae284 phy: freescale: phy-fsl-imx8-mipi-dphy: Add i.MX8qxp LVDS PHY mode support ) breaks the display for us:
[ 1.360769] phy phy-30a00300.dphy.0: Failed to configure PHY with invalid PHY mode: 0
[ 1.360776] nwl-dsi 30a00000.mipi-dsi: [drm:nwl_dsi_bridge_mode_set] *ERROR* Failed to configure DSI phy: -22

Reverting that one patch makes things work again. What could be missing there? Asking @guido.gunther here first because he signed-off on it.
