[PATCH 0/3] drm/panel: jh057n00900: Move dsi init sequence to prepare

[Guido Günther]

If the panel is wrapped in a panel_bridge it gets prepar()ed before the
upstream DSI bridge which can cause hangs (e.g. with imx-nwl since clocks
are not enabled yet). To avoid this move the panel's first DSI access to
enable() so the upstream bridge can prepare the DSI host controller in
it's pre_enable().

The second patch makes the disable() call symmetric to the above and the third
one just eases debugging.

Guido Günther (3):

  drm/panel: jh057n00900: Move mipi_dsi_dcs_set_display_off to disable()
