It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

The biggest part of the changes are cleanups. Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential dead lock" which hopefully fixes the fb locking issues reported by multiple persons.

Framebuffer cursors are monochrome, so the driver converts the image data to the format that the DIU expects and then programs to hardware accordingly. The support cursor enabling/disabling, we provide two cursor image buffers. One is always blank (all zeroes), and the other contains the real cursor image data. To disable the cursor (used typically for cursor blinking), we just tell the hardware to use the blank cursor data.

The bestcomm driver is moved to drivers/dma (so it will be usable for ColdFire). mpc5121 now provides common dtsi file and existing mpc5121 device trees use it. There are some minor clock init and sparse fixes and updates for various 5200 device tree files from Grant.

Enabling diu interrupt causes an interrupt storm and results in system lockup. The cookie for the interrupt handler function passed to request_irq() is wrong (it must be a pointer to the diu struct, and not the address of the pointer to the diu struct). As a result the interrupt handler can not read diu registers and acknowledge the interrupt. Fix cookie arguments for request_irq() and free_irq(). Registering the diu interrupt handler in probe() must happen before install_fb() calls since this function registers framebuffer devices and if fbcon tries to take over framebuffer after registering a frame buffer device, it will call fb_open of the diu driver and enable the interrupts. At this time the diu interrupt handler must be registered already. Disabling the interrupts in fsl_diu_release() must happen only if all other AOIs are closed. Otherwise closing an overlay plane will disable the interrupts even if the primary frame buffer plane is opened. Add an appropriate check in the release function.

The order of the color component arguments in the MAKE_PF() is not natural and causes some confusion. The generated pixel format values for 24 and 16 bpp depths do not much the values in the comments. Fix the macro arguments to be in the natural RGB order and adjust the arguments for all depths to generate correct pixel format values (equal to the values mentioned in the comments).

As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
