Hi Vikas,
Sorry for the late reply. I now have more time to work on CDF, so delays
should be much shorter.
MIPI DSI support is not available yet. The only reason for that is that I

don't have any MIPI DSI hardware to write and test the code with :-)
The common display framework should definitely support MIPI DSI. I think the
existing MIPI DBI code could be used as a base, so the implementation
shouldn't be too high.
Yeah, i was also thinking in similar lines, below is my though for MIPI DSI support in CDF.
o MIPI DSI support as part of CDF framework will expose
§ mipi_dsi_register_device(mpi_device) (will be called mach-xxx-dt.c file )
§ mipi_dsi_register_driver(mipi_driver, bus ops) (will be called from platform specific init driver call )
· bus ops will be
o read data
o write data
o write command
§ MIPI DSI will be registered as bus_register()
When MIPI DSI probe is called, it (e.g., Exynos or OMAP MIPI DSI) will initialize the MIPI DSI HW IP.
This probe will also parse the DT file for MIPI DSI based panel, add the panel device (device_add() ) to kernel and register the display entity with its control and video ops with CDF.
I can give this a try. Does the existing Exynos 5250 driver support MIPI DSI ?
Is the device documentation publicly available ? Can you point me to a MIPI
DSI panel with public documentation (preferably with an existing mainline
driver if possible) ?
yeah, existing Exynos 5250 driver support MIPI DSI ass well as eDP.
i think device documentation is NOT available publicly.
