To properly support the various plane formats supported by different
hardware, the kernel must know the pixel format of a framebuffer object.
So add a new ioctl taking a format argument corresponding to a fourcc
name from the new drm_fourcc.h header file. Implement the fb creation
hooks in terms of the new mode_fb_cmd2 using helpers where the old
bpp/depth values are needed.
v2: create DRM specific fourcc header file for sharing with libdrm etc
v3: fix rebase failure and use DRM fourcc codes in intel_display.c and
update commit message
v4: make fb_cmd2 handle field into an array for multi-object formats
pull in Ville's fix for the memcpy in drm_plane_init
apply Ville's cleanup to zero out fb_cmd2 arg in drm_mode_addfb
v5: add 'flags' field for interlaced support (from Ville)

Subject: [PATCH] drm: Make the per-driver file_operations struct const
The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.
This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

Add support for GTT based scrolling. Instead of pushing bits around we simply
use the GTT to change the mappings. This provides us with a very fast way to
scroll the display providing we have enough memory to allocate on 4K line
boundaries. In practice this seems to be the case except for very big displays
such as HDMI. It works out nicely on the usual configurations are netbooks and
tablets.

If we are the console then a printk can hit us with a spin lock held (and
in fact the kernel will do its best to take printing lock).
In that case we cannot politely sleep when synching after an accelerated op
but must behave obnixously to be sure of getting the bits out.

Kirill Shutemov found problems with the non-upstream IMG driver where the
use of extra DRM encoder/connector types caused random crashes when the DRM
layer tried to display their matching name. This removes the MIPI types
matching the changes Pauli Nieminen made to the non upstream driver set.
As Pauli points out:
" MIPI (or DSI) is protocol specification on top of LVDS serial bus. That
makes it resonable to call MIPI connectors and encoders LVDS."
(and indeed they may also be HDMI convertors or similar when we want to
report a more useful to end user result)
