41814cfc01 OMAP: DSS2: OMAPFB: Allow usage of def_vrfb only for omap2,3
VRFB is supported only on OMAP2 and OMAP3 platforms. If VRFB rotation is
not supported by the hardware and the user requests VRFB rotation,
print a warning and ignore the request from the user.

85a00d9bbf efifb: check that the base address is plausible on pci systems
Some Apple machines have identical DMI data but different memory
configurations for the video.  Given that, check that the address in our
table is actually within the range of a PCI BAR on a VGA device in the
machine.

This also fixes up the return value from set_system(), which has always
been wrong, but never resulted in bad behavior since there's only ever
been one matching entry in the dmi table.

The patch

1) stops people's machines from crashing when we get their display wrong,
   which seems to be unfortunately inevitable,

2) allows us to support identical dmi data with differing video memory
   configurations

This also adds me as the efifb maintainer, since I've effectively been
acting as such for quite some time.

c07fbfd17e fbmem: VM_IO set, but not propagated
When we setup up the VMA flags for the mmap flag and we end up using the
fallback mmap functionality we set the vma->vm_flags |= VM_IO.  However we
neglect to propagate the flag to the vma->vm_page_prot.

This bug was found when Linux kernel was running under Xen.  In that
scenario, any page that has VM_IO flag to it, means that it MUST be a
MMIO/VRAM backend memory , _not_ System RAM.  That is what the fbmem.c
does: sets VM_IO, ioremaps the region - everything is peachy.

Well, not exactly.  The vm_page_prot does not get the relevant PTE flags
set (_PAGE_IOMAP) which under Xen is a death-kneel to pages that are
referencing real physical devices but don't have that flag set.

This patch fixes this.

a8bdabca3a s3c-fb: protect window-specific registers during updates

shadow registers during reconfiguration.  Add protect calls for set_par

067b226b9e s3c-fb: add support for display panning
Supports all bpp modes.

The PRTCON register is used to disable in-hardware updates of registers
that store start and end addresses of framebuffer memory.  This prevents
display corruption in case we do not make it before VSYNC with updating
them atomically.  With this feature there is no need to wait for a VSYNC
interrupt before each such update.

cd7d7e0244 s3c-fb: fix various null references on framebuffer memory alloc failure
The following problems were found in the above situation:

sfb->windows[win] was being assigned at the end of s3c_fb_probe_win only.
This resulted in passing a NULL to s3c_fb_release_win if probe_win
returned early and a memory leak.

dma_free_writecombine does not allow its third argument to be NULL.

fb_dealloc_cmap does not verify whether its argument is not NULL.

Update the variant and window variant structures with the necessary
changes to support the older style of hardware where these are not in the
same place.

Add the support for the s3c2443/s3c2416 hardware by using the
platform-device s3c2443 to cover both, and add the initialisation data for
these.

Also change to including just the v4 header files for the moment until the

It has been working fine at 16bpp but in case of pixel format more then
24bpp it would occur distortedness situation on that mode.  so this patch
set the word swap control bit of WINCONx to 1 as default value.  but it
should be set to 0 in case that each ENLOCAL bit of WINCON0 ~ 2 registers
is enabled.  this issue would be solved with local path feature soon.
