[PATCH 0/4] drm/panel: Support for OSD101T2045-53TS and OSD101T2587-53TS
Hi, Add support for OSD101T2045-53TS and OSD101T2587-53TS from One Stop Displays. The two panel is similar with one big difference: OSD101T2587-53TS requires the MIPI_DSI_TURN_ON_PERIPHERAL message, thus can not be handled by panel-simple.

[PATCH 4/4] drm/panel: Add OSD101T2587-53TS driver
The panel is similar to OSD101T2045-53TS (which is handled by panel-simple)
with one big difference: osd101t2587-53ts needs MIPI_DSI_TURN_ON_PERIPHERAL
message to be sent from the host to be operational and thus can not be
handled by panel-simple.
