all review comments should be addressed.

The remove function should disable the panel by
calling the unprepare() function before the panel
is disconnected from MIPI bus instead of trying
to reset it.

In preparation for removing custom DSS calls from the DSI
panel driver, this moves support for external tearing event
GPIOs into the DSI host driver. This way tearing events are
always handled in the core resulting in simplification of
the panel drivers.
The TE GPIO acquisition follows works in
For the scenario where user may require to modeset with a mode
supporting a fractional value for vertical refresh-rate,
appropriate mode can be selected by searching for mode
having matching fractional vertical refresh rate using
below equation.
vrefresh = (1000 * pixel clock) / (htotal * vtotal)
This prepares the driver for becoming a mipi_dsi_host implementation,
which provides a generic transfer function instead of all kind of
different read/write functions. The implementation will become more
elegant after unexporting the specific functions in the following
patches.

This moves from custom platform driver infrastructure to mipi_dsi_host

The only thing left for generalizing mdev is the VFIO specific parent
ops. This is basically the open/release/read/write/ioctl/mmap.
To support this, mdev core is extend to support a specific size
of structure during create, this will allow to compose mdev structure
into mdev vfio structure and
Current mdev is tied to a VFIO specific "mdev" bus. This prevent mdev
from being used by other types of API/buses. So this patch tries to make
mdev bus agnostic through making a mdev core a thin module:
- decouple VFIO bus specific bits from mdev_core.c to mdev_vfio.c and
introduce mdev_vfio
