drivers/video: fsl-diu-fb: use an enum for the AOI index
Each of the five AOIs created by the DIU driver has a special purpose, and
they're not treated equally. It makes sense to identify them with an enum
instead of a hard-coded number.
Since the 'index' is now an enum, it can only contain allowed values, so
there's no need to check for an invalid value. This simplifies some other
code, such as fsl_diu_disable_panel(), which no longer needs to return an
error code.

drivers/video: fsl-diu-fb: remove broken screen blanking support
The function which is supposed to provide screen blanking support doesn't
actually do anything, so the framebuffer layer thinks the screen has
been blanked when it really isn't. Remove the code completely for now.
A side-effect of this change is that the framebuffer console blanking now
works correctly. Presumably this is because the console now receives -EINVAL
instead of '0' when it asks the driver to blank the screen, so the console
does it manually now.
A signficant refactoring of the driver is planned, and proper hardware
blanking support will added afterwards.

fb: sh-mobile: Fix deadlock risk between lock_fb_info() and console_lock()
Following on Herton's patch "fb: avoid possible deadlock caused by
fb_set_suspend" which moves lock_fb_info() out of fb_set_suspend()
to its callers, correct sh-mobile's locking around call to
fb_set_suspend() and the same sort of deaklocks with console_lock()
due to order of taking the lock.
console_lock() must be taken while fb_info is already locked and fb_info
must be locked while calling fb_set_suspend().
fb: avoid possible deadlock caused by fb_set_suspend
A lock ordering issue can cause deadlocks: in framebuffer/console code,
all needed struct fb_info locks are taken before acquire_console_sem(),
in places which need to take console semaphore.
But fb_set_suspend is always called with console semaphore held, and
inside it we call lock_fb_info which gets the fb_info lock, inverse
locking order of what the rest of the code does. This causes a real
deadlock issue, when we write to state fb sysfs attribute (which calls
fb_set_suspend) while a framebuffer is being unregistered by
remove_conflicting_framebuffers, as can be shown by following show
blocked state trace on a test program which loads i915 and runs another
forked processes writing to state attribute:
fb-test2 which reproduces above is available on kernel.org bug #26232.
To solve this issue, avoid calling lock_fb_info inside fb_set_suspend,
and move it out to where needed (callers of fb_set_suspend must call
lock_fb_info before if needed). So far, the only place which needs to
call lock_fb_info is store_fbstate, all other places which calls
fb_set_suspend are suspend/resume hooks that should not need the lock as
they should be run only when processes are already frozen in
suspend/resume.

both clocks are provided by using bus clock such as HCLK. However, EXYNOS4

The driver selects enabling lcd clock according to has_clksel which means
