2008-07-24fsl-diu-fb: update Freescale DIU driver to use page_alloc_exact()Timur Tabi
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.

2008-07-08Fix broken fix for fsl-diu-dbTakashi Iwai
On 2.6.26-rc9, the commit 05946bce839b4fed5442dbfab77060fb75e051f3 ("fsl_diu_fb: fix build with CONFIG_PM=y, plus fix some warnings") breaks its previous fix f969c5672b16b857e5231ad3c78f08d8ef3305aa ("fsl-diu-db: compile fix") This patch reverts the broken part.

2008-07-04fsl_diu_fb: fix build with CONFIG_PM=y, plus fix some warningsAnton Vorontsov
This patch fixes following build error when CONFIG_PM is set. CC drivers/video/fsl-diu-fb.o drivers/video/fsl-diu-fb.c: In function 'fsl_diu_suspend': drivers/video/fsl-diu-fb.c:1327: error: 'ofdev' undeclared (first use in this function) drivers/video/fsl-diu-fb.c:1327: error: (Each undeclared identifier is reported only once drivers/video/fsl-diu-fb.c:1327: error: for each function it appears in.) drivers/video/fsl-diu-fb.c: In function 'fsl_diu_resume': drivers/video/fsl-diu-fb.c:1337: error: 'ofdev' undeclared (first use in this function) While I'm at it, also fix this warning: drivers/video/fsl-diu-fb.c: In function 'fsl_diu_alloc': drivers/video/fsl-diu-fb.c:314: warning: format '%lx' expects type 'long unsigned int', but argument 3 has type 'phys_addr_t' And these section mismatches: ..from the function fsl_diu_remove() to the function .exit.text:uninstall_fb() ..from the function fsl_diu_remove() to the function .exit.text:uninstall_fb() ..from the function install_fb() to the variable .devinit.data:fsl_diu_mode_db ..from the function install_fb() to the variable .devinit.data:fsl_diu_mode_db ..from the function fsl_diu_probe() to the function .exit.text:uninstall_fb() ..from the function fsl_diu_probe() to the function .exit.text:uninstall_fb() Also, some sparse fixes: make two functions static, and use NULL where appropriate. There are still a lot of sparse warnings, mainly wrt absence of __iomem annotations, but some will require ugly __force stuff. I'll leave them for now, since proper fix would be not that trivial as few one-liners below.

2008-04-28fbdev: powerpc: driver for Freescale 8610 and 5121 DIUYork Sun
The following features are supported: plane 0 works as a regular frame buffer, can be accessed by /dev/fb0 plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2 plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4 Special ioctls support AOIs All /dev/fb* can be used as regular frame buffer devices, except hardware change can only be made through /dev/fb0. Changing pixel clock has no effect on other fbs. Limitation of usage of AOIs: AOIs on the same plane can not be horizonally overlapped AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1 AOIs can not beyond phisical display area. Application should check AOI geometry before changing physical resolution on /dev/fb0 required command line parameters to preallocate memory for frame buffer diufb. optional command line parameters to set modes and monitor video=fslfb:[resolution][,bpp][,monitor] Syntax: Resolution xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60 Bpp bpp=32, bpp=24, or bpp=16 Monitor monitor=0, monitor=1, monitor=2 0 is DVI 1 is Single link LVDS 2 is Double link LVDS Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching monirot port for MPC5121ADS has no effect. If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.
