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. Signed-off-by:

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. Signed-off-by:

The fourth bit of the background color is the blink property bit, not the intensity bit, as for the foreground color. Therefore it shouldn't be included in the background color. Signed-off-by:

There is nothing to gain by converting value in kHz to fixed point MHz. Just calculate everything in kHz. A reorder of the loop allows reducing number of iterations (check if frequency is not too high already). Signed-off-by:

This patch contains the following cleanups: - make the needlessly global amifb_init() static - rename cleanup_module() to amifb_exit(), make it static __exit, use module_exit(), there's no need to #ifdef MODULE it Signed-off-by:

Simply enabling DAC blanking without turning off the CRT seems to be resulting in characters remaining on the screen when the monitor blanks. This patch turns off the CRT for all modes, and also powers down the DACs when vsync and/or hsync are disabled. Signed-off-by:

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. [akpm@linux-foundation.org: fix printk warnings] Signed-off-by:

As pointed out by Andrew Morton, we have a problem when setting the 64bit resources option. Alter the allocation routines to remove the need to use the start and end fields, use the proper HEAD_PANEL/HEAD_CRT and update the comments. Note, we also fix the bug where we failed to check the size of the CRT memory allocation. [akpm@linux-foundation.org: cleanup] Signed-off-by:

Add the ability to register only one of the two possible main framebuffer devices on the SM501 by passing platform data for only the framebuffer that you are interested in having. As a side note, we update the init sequence to commonise the code that is executed twice, and fix a pair of missing frees that we didn't do on framebuffer exit, such as freeing the fb's cmap.

Avoid division by zero in atmel_lcdfb_check_var() function. If pixclock is not specified while passing a var structure in the check_var() funtion, a division by zero occurs (when translating pixclock to KHz). This patch adds a checking of this value and try to choose a video mode in the modelist. The mode found in the probe function in added to the modelist.

Remove dead code. This will slightly change the behaviour of the driver on systems that support backlight control. Previously they would just turn the backlight off using the backlight control but now the generic LCD code will also turn off the LCD using the POWER_MANAGEMENT register. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
