* backlight: Allow properties to be passed at registrationMatthew Garrett2010-03-161-2/+5
| | | | | | | | | | Values such as max_brightness should be set before backlights are registered, but the current API doesn't allow that. Add a parameter to backlight_device_register and update drivers to ensure that they set this correctly.

* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

* fb: nvidiafb: Try harder at initial mode setting.Paul Mundt2008-02-061-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current nvidiafb_check_var() simply bails out if the selected mode is out of range of the panel dimensions. A good question would be why the bogus mode is being selected in the first place -- the panel dimensions that are read back are certainly bogus, but alas, I have no idea where to even begin looking at the i2c/EDID/DDC mess: nvidiafb: Device ID: 10de0165 nvidiafb: CRTC0 analog not found nvidiafb: CRTC1 analog not found nvidiafb: EDID found from BUS1 nvidiafb: CRTC 0 is currently programmed for DFP nvidiafb: Using DFP on CRTC 0 nvidiafb: Panel size is 1280 x 1024 nvidiafb: Panel is TMDS nvidiafb: unable to setup MTRR nvidiafb: Flat panel dithering disabled nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000) In my .config I presently have: CONFIG_FIRMWARE_EDID=y CONFIG_FB_DDC=y CONFIG_FB_NVIDIA_I2C=y I've not tried fiddling with these options, as I haven't the vaguest idea what I should be looking at. As a workaround, simply groveling for a new mode based on the probed dimensions seems to work ok. While it would be nice to debug this further and sort out why the panel information is bogus, I think it's still worth retrying the mode based on the panel information at hand as a last-ditch effort, rather than simply bailing out completely.

* nvidiafb: Add boot option to reverse i2c port assignmentAntonino A. Daplas2007-10-163-4/+11
| | | | | | | | | | | | | | | | | | | There are a few nvidia hardware where the i2c port assignments are reversed, i.e., the 1st i2c port is assigned to the secondary display and the 2nd i2c port to the primary display. In most cases, if only 1 display is attached, or if only 1 flatpanel and 1 analog display is attached, the port reversal is of no consequence. However if 2 flatpanels are attached, it can cause display problems. There is no sane way of determining if the hardware reversed the i2c port assignment, so the simplest fix is to add a boot/module option, "reverse_i2c to explicitly reverse the i2c port. This also restores i2c ordering back to the pre-2.6.22 state.

Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-142-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
