The linux FB does _not_ support smart panels, there are no driver
support for this kind of device (after the searches I have done).
I have been involved myself writing a driver for this kind of device
but my limited knowledge of Kernel programming has led to a very
limited "driver" using GPIOs instead of the hardware driver.
It can be implemented by using the proper descriptors && doing DMA.
Also I don't think such a driver could make it to the mainline since it
is very LCD specific especially for the command list.
Integrating it to the pxafb driver would be nice though.
