This patch is a bugfix for the use of cfb_* functions instead of sys_* functions. sys_* should be used with vmalloced framebuffers. the previous cfb_ use would not work for callers of imageblit/etc. Signed-off-by:

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. Signed-off-by:

Mostly signedness fixes. nv10_sim_state existence in both drivers suggests that one of them should be removed, but that's for later. Signed-off-by:

Since there's no way to autodetect panel modes, we're forced to hardcode them in the driver and add a big fat #ifdef. The OLPC DCON needs a specific mode line (at 1200x900). This adds it to both gxfb and lxfb. (Jordan said: We could probably detect the panel mode, but there isn't any reason to since the panel timings are well known and won't change. While OFW detection would be good computer science fu, it would be a wasted effort since its so easy to hard code them into the table.) Signed-off-by:

If there's no VSA2 (ie, if we're using tinybios or OpenFirmware), use the GLIU's P2D Range Offset Descriptor to determine how much memory we have available for the framebuffer. Originally based on a patch by Jordan Crouse. Tested with OpenFirmware; Pascal informs me that tinybios has a stub that fills in P2D_RO0. Signed-off-by:

This adds the ability to suspend/resume the lxfb driver, which includes: - Register and palette saving code; registers are stored in lxfb_par. A few MSR values are saved as well. - lx_powerup and lx_powerdown functions which restore/save registers and enable/disable graphic engines. - lxfb_suspend/lxfb_resume Originally based on a patch by Jordan Crouse.

Finally drop the last remnants of df_regs, using vp_regs instead. Also, drop panel_width and panel_height from lxfb_par; they're unused. Signed-off-by:

Andres Salomon authored
- Rename various bitfield defines to match the data sheet names. - Rename DF_ register definitions to VP_ to match the data sheet; ie, DF_PAR -> VP_PAR. - for GP/DC registers, rather than defining to specific addresses, use an enum to number them sequentially and just multiply by 4 (bytes) to access them (in read_*/write_* functions). - for VP/FP registers, use an enum and multiple by 8 (bytes). They're 64bit registers. Signed-off-by:

Andres Salomon authored
This creates read_gp/write_gp, read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for reading and updating those registers. Note that we don't follow the 'DF' naming; those will be renamed to VP shortly. Signed-off-by:

Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25 MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some intermediate steps between pre-existing frequencies. Signed-off-by:

Adds different wiring mode for the LCD screen. The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead "RGB-565". The major part of graphic stacks for embedded systems uses only "RGB-565". It is possible to swap LCD IOs instead of doing this bit swapping by software (See application note AT91SAM9 LCD Controller http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf) This wire swapping is done on the at91sam9rl-ek board (board code using this patch will come later).

Teach atmel_lcdfb driver how to suspend/resume. Note that the backlight control should probably do more of the same stuff: turning off display power (more than just the backlight) and stopping the clocks (and dma to drive the no-longer-seen display). No point in wasting power to generate images that can't be observed, after all... Signed-off-by:

If the user specified a fixed framebuffer address on the command line, it may have been initialized already with a splash image or something, so we shouldn't clear it. Therefore, we should only initialize the framebuffer if we allocated it ourselves. This patch also updates the AVR32 setup code to clear the framebuffer if it allocated it itself, i.e. the user didn't provide a fixed address or the reservation failed. I've updated the at91 platform code as well so that it initializes the framebuffer if it is located in SRAM, but I haven't tested that it actually works. Signed-off-by:

There is no reason to drive the savagefb I2C bus at such a low speed, so bump it from 12.5 kbps to 50 kbps. The Intel (i810) and Matrox framebuffer drivers already run their I2C bus at this speed, and so are the legacy i2c-savage4 and i2c-prosavage drivers. Signed-off-by:

Don't treat valid modes returned by fb_find_mode() (best-fit modes, default modes or the first valid mode) as errors. Currently, when fb_find_mode() finds a valid mode belonging to one of the above-mentioned classes, uvesafb will ignore it and will try to set a 640x480 video mode. The expected behaviour (introduced by this patch) would be to use the valid mode returned by fb_find_mode() instead. Signed-off-by:
