* atmel_lcdfb: wiring BGR to RGB color modeNicolas Ferre2008-04-281-0/+10
| | | | | | | | | | | | | | | | | | | | | | 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).

* atmel_lcdfb: suspend/resume supportDavid Brownell2008-04-281-0/+1
| | | | | | | | | | | | | | | | | | 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...

* atmel_lcdfb: backlight controlDavid Brownell2008-02-061-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from the LCD controller. It's controlled by "contrast" registers though. This patch lets boards declare that they have that kind of backlight control. The driver can then export this control, letting screenblank and other operations actually take effect ... reducing the typically substantial power drain from the backlight. Note that it's not fully cooked - doesn't force backlight off during system suspend - the "power" and "blank" events may not be done right This should be easily added in the future.

* uvesafb: the driver coreMichal Januszewski2007-10-162-1/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d) to execute calls to the x86 Video BIOS functions. The driver is not limited to any specific arch and whether it works on a given arch or not depends on that arch being supported by the userspace daemon. It has been tested on x86_32 and x86_64. A single BIOS call is represented by an instance of the uvesafb_ktask structure. This structure contains a buffer, a completion struct and a uvesafb_task substructure, containing the values of the x86 registers, a flags field and a field indicating the length of the buffer. Whenever a BIOS call is made in the driver, uvesafb_exec() builds a message using the uvesafb_task substructure and the contents of the buffer. This message is then assigned a random ack number and sent to the userspace daemon using the connector interface. The message's sequence number is used as an index for the uvfb_tasks array, which provides a mapping from the messages coming from userspace to the in-kernel uvesafb_ktask structs. The userspace daemon performs the requested operation and sends a reply in the form of a uvesafb_task struct and, optionally, a buffer. The seq and ack numbers in the reply should be exactly the same as those in the request. Each message from userspace is processed by uvesafb_cn_callback() and after passing a few sanity checks leads to the completion of a BIOS call request.

* [PATCH] neofb: avoid resetting display config on unblank (v2)Christian Trefzer2006-02-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were two mistakes in the register-read-on-(un)blank approach. - First, without proper register (un)locking the value read back will always be zero, and this is what I missed entirely until just now. Due to this, the logic could not be verified at all and I tried some bogus checks which are completely stupid. - Second, the LCD status bit will always be set to zero when the backlight has been turned off. Reading the value back during unblank will disable the LCD unconditionally, regardless of the state it is supposed to be in, since we set it to zero beforehand. So this is what we do now: - create a new variable in struct neofb_par, and use that to determine whether to read back registers (initialized to true) - before actually blanking the screen, read back the register to sense any possible change made through Fn key combo - use proper neoUnlock() / neoLock() to actually read something - every call to neofb_blank() determines if we read back next time: blanking disables readback, unblanking (FB_BLANK_UNBLANK) enables it This should give us a nice and clean state machine. Has been thoroughly tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached CRT in all possible combinations of LCD/CRT on/off. I changed the config via Fn key, let the console blank, unblanked by keypress - works flawlessly. Signed-off-by: Christian Trefzer <ctrefzer@gmx.de> Cc: "Antonino A.

* [PATCH] Update cyblafb driverKnut Petersen2006-01-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | This is a major update to the cyblafb framebuffer driver. Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | Separate out the Sharp Zaurus c7x0 series specific code from the Corgi Touchscreen driver. Use the new functions in corgi_lcd.c via sharpsl.h for hsync handling and pass the IRQ as a platform device resource. Move a function prototype into the w100fb header file where it belongs. This enables the driver to be used by the Zaurus cxx00 series.

* [PATCH] framebuffer: new driver for cyberblade/i1 graphics coreKnut Petersen2005-09-091-0/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a framebuffer driver for the Cyberblade/i1 graphics core. Currently tridenfb claims to support the cyberblade/i1 graphics core. This is of very limited truth. Even vesafb is faster and provides more working modes and a much better quality of the video signal. There is a great number of bugs in tridentfb ... but most often it is impossible to decide if these bugs are real bugs or if fixing them for the cyberblade/i1 core would break support for one of the other supported chips. Tridentfb seems to be unmaintained,and documentation for most of the supported chips is not available. So "fixing" cyberblade/i1 support inside of tridentfb was not an option, it would have caused numerous if(CYBERBLADEi1) else ... cases and would have rendered the code to be almost unmaintainable. A first version of this driver was published on 2005-07-31. A fix for a bug reported by Jochen Hein was integrated as well as some changes requested by Antonino A. Daplas. A message has been added to tridentfb to inform current users of tridentfb to switch to cyblafb if the cyberblade/i1 graphics core is detected. This patch is one logical change, but because of the included documentation it is bigger than 70kb. Therefore it is not sent to lkml and linux-fbdev-devel, Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Cc: Muli Ben-Yehuda <mulix@mulix.org> Acked-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
