Driver for Intel FPGA Video and Image Processing Suite Frame Buffer
II.
The driver only supports the Intel Arria10 devkit and its variants.
This driver can be either loaded staticlly or in modules.
The OF device tree binding is located at:
Documentation/devicetree/bindings/display/altr,vip-fb2.txt

Please use drm_fbdev_generic_setup() for fbdev emulation. It tears
down
automatically on drm_dev_unregister() and you don't need the
drm_driver->lastclose hook.
All drivers that use drm_fbdev_cma_init() will move to this shortly.

I could not find any examples that currently uses
the drm_fbdev_generic_setup (). Would you mind pointing me on where
such examples are available that would allow me to replace the
assignment of the fbcma pointer with drm_fbdev_generic_setup() method
This is the only one converted so far:

drm/tinydrm: Use drm_fbdev_generic_setup()
