2011-10-05drivers/video: fsl-diu-fb: only DIU modes 0 and 1 are supportedTimur Tabi
The Freescale DIU video controller supports five video "modes", but only the first two are used by the driver. The other three are special modes that don't make sense for a framebuffer driver. Therefore, there's no point in keeping a global variable that indicates which mode we're supposed to use.

2011-10-05drivers/video: fsl-diu-fb: move some definitions out of the header fileTimur Tabi
Move several macros and structures from the Freescale DIU driver's header file into the source file, because they're only used by that file. Also delete a few unused macros. The diu and diu_ad structures cannot be moved because they're being used by the MPC5121 platform file. A future patch eliminate the need for the platform file to access these structs, so they'll be moved also.

2011-10-05drivers/video: fsl-diu-fb: fix some ioctlsTimur Tabi
Use the _IOx macros to define the ioctl commands, instead of hard-coded numbers. Unfortunately, the original definitions of MFB_SET_PIXFMT and MFB_GET_PIXFMT used the wrong value for the size, so these macros have new values now. To avoid breaking binary compatibility with older applications, we retain support for the original values, but the driver displays a warning message if they're used. Also remove the FBIOGET_GWINFO and FBIOPUT_GWINFO ioctls. FBIOPUT_GWINFO was never implemented, and FBIOGET_GWINFO was never used by any application.

2011-09-18drivers/video: fsl-diu-fb: remove unusued MEM_ALLOC_THRESHOLDTimur Tabi
If there was ever any code that used MEM_ALLOC_THRESHOLD, it was removed a long time ago. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-09-18drivers/video: fsl-diu-fb: the video buffer is not I/O memoryTimur Tabi
The video buffer is not uncached memory-mapped I/O, so don't tag the virtual address as __iomem. It's also not a u8*. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-09-18drivers/video: fsl-diu-fb: remove unused ioctlsTimur Tabi
Remove some unused ioctl commands, and treat those commands as unsupported instead of ignored. Also remove struct mfb_alpha, which isn't used by any ioctl. It may have been once intended for MFB_SET_ALPHA, but that ioctl uses a different data structure.

2011-06-24fsl-diu-fb: remove check for pixel clock rangesTimur Tabi
The Freescale DIU framebuffer driver defines two constants, MIN_PIX_CLK and MAX_PIX_CLK, that are supposed to represent the lower and upper limits of the pixel clock. These values, however, are true only for one platform clock rate (533MHz) and only for the MPC8610. So the actual range for the pixel clock is chip-specific, which means the current values are almost always wrong. The chance of an out-of-range pixel clock being used are also remote. Rather than try to detect an out-of-range clock in the DIU driver, we depend on the board-specific pixel clock function (e.g. p1022ds_set_pixel_clock) to clamp the pixel clock to a supported value.

2010-11-15fsl-diu-fb: drop dead ioctl defineMike Frysinger
The fsl-diu-fb driver no longer uses this define, and we have a common one to cover this already (FBIO_WAITFORVSYNC). Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-08-01powerpc/5121: move fsl-diu-fb.h to include/linuxAnatolij Gustschin
Some DIU structures will be used in platform code in subsequent MPC5121 DIU patch, so we move this header to be able to include it elsewhere. Signed-off-by: Anatolij Gustschin <agust@denx.de> Acked-by: Timur Tabi <timur@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
