2008-04-28atmel_lcdfb: wiring BGR to RGB color modeNicolas Ferre
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).

2008-04-28atmel_lcdfb: suspend/resume supportDavid Brownell
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...

2008-04-28atmel_lcdfb: don't initialize a pre-allocated framebufferHaavard Skinnemoen
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.

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.

2008-04-28PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switchAndres Salomon
Prior to suspend, we allocate and switch to a new VT; after suspend, we switch back to the original VT. This can be slow, and is completely unnecessary if the framebuffer we're using can restore video properly. This adds a hook that allows drivers to select whether or not to do this vt switch, and changes the gxfb driver to call this hook. It also adds a module param to gxfb to allow controlling of the vt switch (defaulting to no switch). (Note: I'm not convinced that console_sem is the best way to protect this, but we should probably have some form of locking..)

We want to stop sharing stuff with gx1fb; it makes little sense.

The last few patches moved most stuff into gxfb.h anyways, so there was very little left. - Drop the geode_{dc,vid}_ops stuff. Un-static functions, add declarations to gxfb.h.

mode Currently, if a perfect match in terms of resolution is not found, fb_find_mode() only looks for a best-fit mode among modes with a higher resolution than the one requested. Thus, if the user requests a resolution higher than the largest supported one, they are dropped to the default mode (usually a low resolution one). Change this behaviour so that all valid video modes are considered when looking for a best-fit mode, while still preferring modes with a higher resolution.

2008-04-19[ARM] pxa: separate GPIOs and their mode definitions to pxa2xx-gpio.heric miao
two reasons: 1. GPIO namings and their mode definitions are conceptually not part of the PXA register definitions 2. this is actually a temporary move in the transition of PXA2xx to use MFP-alike APIs (as what PXA3xx is now doing), so that legacy code will still work and new code can be added in step by step Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-03-19fbdev: defio and MetronomefbJaya Kumar
Implement support for the E-Ink Metronome controller. It provides an mmapable interface to the controller using defio support. It was tested with a gumstix pxa255 with Vizplex media using Xfbdev and various X clients such as xeyes, xpdf, xloadimage. This patch also fixes the following bug: Defio would cause a hang on write access to the framebuffer as the page fault would be called ad-infinitum. It fixes fb_defio by setting the mapping to be used by page_mkclean. Signed-off-by: Jaya Kumar <jayakumar.lkml@gmail.com> Cc: "Antonino A.

2008-03-19i810fb: fix console switch regressionStefan Bauer
Since 4c7ffe0b9f7f40bd818fe3af51342f64c483908e ("fbdev: prevent drivers that have hardware cursors from calling software cursor code") every call of i810fb_cursor fails with -ENXIO because of a incorrect "!". This hasn't struck until eaa0ff15c30dc9799eb4d12660edb73aeb6d32c5 ("fix ! versus & precedence in various places") surrounded the expression with braces, so that the intended behavior was inverted. That caused 'pixel waste' - the same line of multi-colored pixels repeated over the whole screen - during console switch. This switches back to the original pre-4c7ffe0 behavior.
