The ioctl interface in the Freescale DIU framebuffer driver is just a collection of miscellaneous functions which were only used in a one-time demo application that was never distributed. Plus, the ioctls were spread across two types (both conflicting), and the demo app didn't even use all of them. Removing the ioctl interface also allows us to clean up the header file and remove other unusued stuff. Signed-off-by: Timur Tabi <timur@freescale.com> --- There's a warning about dummy_ad_addr that will be fixed in a future patch.
