.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.

The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated. This patch
makes all readers of these elements use device.of_node instead.
(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

Made necessary by 6992f53349 ("sysfs: Use
one lockdep class per sysfs attribute").
Prevents further "key xxx not in .data" bug-reports. Although some
attributes could probably be converted to static ones, this is left for
people having hardware to test.

Remove call to the fsl_diu_set_par before the register_framebuffer().

Add a mutex to avoid a circular locking problem between the mm layer
semaphore and fbdev ioctl mutex through the fb_mmap() call.
Also, add mutex to all places where smem_start and smem_len fields change
so the mutex inside the fb_mmap() is actually used. Changing of these
fields before calling the framebuffer_register() are not mutexed.
This is 2.6.31 material. It removes one lockdep (fb_mmap() and
register_framebuffer()) but there is still another one (fb_release() and
register_framebuffer()). It also cleans up handling of the smem_start and
smem_len fields used by mutexed section of the fb_mmap().

Update the Freescale DIU driver to use page_alloc_exact() to allocate a
DMA buffer. This also eliminates the rheap-based memory allocator. We
can do this now because commit 6ccf61f9 allows us to allocate 8MB
physically- contiguous memory blocks.

This patch fixes following build error when CONFIG_PM is set.
CC drivers/video/fsl-diu-fb.o
drivers/video/fsl-diu-fb.c: In function 'fsl_diu_suspend':
drivers/video/fsl-diu-fb.c:1327: error: 'ofdev' undeclared (first use in this function)
drivers/video/fsl-diu-fb.c:1327: error: (Each undeclared identifier is reported only once

drivers/video/fsl-diu-fb.c: In function 'fsl_diu_resume':
drivers/video/fsl-diu-fb.c:1337: error: 'ofdev' undeclared (first use in this function)
While I'm at it, also fix this warning:
drivers/video/fsl-diu-fb.c: In function 'fsl_diu_alloc':
drivers/video/fsl-diu-fb.c:314: warning: format '%lx' expects type 'long unsigned int', but argument 3 has type 'phys_addr_t'
And these section mismatches:
..from the function fsl_diu_remove() to the function .exit.text:uninstall_fb()
..from the function fsl_diu_remove() to the function .exit.text:uninstall_fb()
..from the function install_fb() to the variable .devinit.data:fsl_diu_mode_db
..from the function install_fb() to the variable .devinit.data:fsl_diu_mode_db
..from the function fsl_diu_probe() to the function .exit.text:uninstall_fb()
..from the function fsl_diu_probe() to the function .exit.text:uninstall_fb()
Also, some sparse fixes: make two functions static, and use NULL where
appropriate. There are still a lot of sparse warnings, mainly wrt absence
of __iomem annotations, but some will require ugly __force stuff. I'll leave
them for now, since proper fix would be not that trivial as few one-liners
below.

The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs
All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0. Changing pixel clock has no effect
on other fbs.
Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0
required command line parameters to preallocate memory for frame buffer diufb.
optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:
Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60
Bpp
bpp=32, bpp=24, or bpp=16
Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS
Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.
If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.
