5bb49fcd50 video/fb: cleanup FB_MAJOR usage
Currently, linux/major.h defines a GRAPHDEV_MAJOR (29) that nobody uses,
and linux/fb.h defines the real FB_MAJOR (also 29), that only fbmem.c
needs.  Drop GRAPHDEV_MAJOR from major.h, move FB_MAJOR definition from
fb.h to major.h, and fix fbmem.c to use major.h's definition.

3e074058d7 fbdev: LCD backlight driver using Atmel PWM driver
This patch adds a platform driver using the ATMEL PWM driver to control a
backlight which requires a PWM signal and optional GPIO signal for discrete
on/off signal.  It has been tested on Favr-32 board from EarthLCD.

The driver is configurable by supplying a struct with the platform data.  See
the include/linux/atmel-pwm-bl.h for details.

The board code for Favr-32 will be submitted to the AVR32 kernel list.

b604838ac6 vfb: only enable if explicitly requested when compiled in
The Kconfig help for the vfb driver says:
   Do NOT enable it for normal systems! To protect the innocent, it
   has to be enabled explicitly at boot time using the kernel option
   `video=vfb:'.

This change lets the code match the description.

Support for vfb:disable is kept for backwards compatibility; vfb:off works
because it is tested at a higher level.

Note: any undefined option (e.g. vfb:enable) will also enable this driver.

The relevant code has been unchanged since before the migration to
git (2.6.12).

This patch fixes bugzilla #9310 and was the root cause behind
http://lkml.org/lkml/2008/5/31/220.

cfb4f5d175 fbdev: SuperH Mobile LCDC Driver
This is the SuperH Mobile LCDC frame buffer driver V2, adding support for
the LCDC block found in SuperH Mobile processors.  The hardware supports
up to two LCD panels per LCDC block, and both RGB and SYS interfaces can
be used to hook up LCD panels/modules.

The device driver is a regular platform driver, so LCD configuration and
board specific hooks are passed to the driver using platform data.  LCD
modules using SYS interface often require special configuration using the
SYS bus, and to solve this cleanly the driver provides SYS interface
operations to the board code.

Tested on sh7723 and sh7722 processors with a SYS16A QVGA panel and WVGA
panels using RGB16 and RGB18 interfaces.

012e26096b uvesafb: change mode parameter to mode_option
Make more drivers use the "mode_option" parameter.  This one is quite new
so drop the old "mode" parameter before someone starts using it seriously.

fcea8030b3 drivers/video/aty/radeon_base.c: notify user if sysfs_create_bin_file() failed
Current kernel builds warn about:
drivers/video/aty/radeon_base.c: In function 'radeonfb_pci_register':
drivers/video/aty/radeon_base.c:2334: warning: ignoring return value of 'sysfs_create_bin_file', declared with attribute warn_unused_result
drivers/video/aty/radeon_base.c:2336: warning: ignoring return value of 'sysfs_create_bin_file', declared with attribute warn_unused_result

Do minimal checking of these functions and issue a warning if either
fails.  They don't seem to be critical..
