* toshiba_acpi: Enable autoloadingarvidjaar@mail.ru2008-03-11
| | | | | | | | | | | | This adds aliases to enable autoloading of toishiba_acpi. Two aliases are defined - TOS6200 (for \\_SB_.VALD.GHCI) and TSO1900 (for \\_SB_.VALZ.GHCI). This allows toishiba_acpi to be autoloaded on systems that provide those devices.

* toshiba_acpi: fix section mismatch in allyesconfigRandy Dunlap2007-06-16
| | | | | | | | | | | | | Fix section error (allyesconfig). The exit function is called from init, so functions that are called by the exit function cannot be marked __exit.

* acpi: fix section mismatch warning in asus + toshibaSam Ravnborg2007-06-01
| | | | | | | | | | | | | | | | | | | Fix following section mismatch warnings in acpi WARNING: drivers/acpi/asus_acpi.o(.init.text+0xb7): Section mismatch: reference to .exit.text: (after 'init_module') WARNING: o-i386/drivers/acpi/toshiba_acpi.o(.init.text+0x13a): Section mismatch: reference to .exit.text: (after 'init_module') The exit function is used in the init function during an error codition. As __exit may be discarded during link-time / run-time this is no good. Do not mark the exit function __exit. Note: This warning is only seen by my local copy of modpost but the change will soon hit upstream.

* backlight: Separate backlight properties from backlight ops pointersRichard Purdie2007-02-20
| | | | | | | | | Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
* backlight: Remove unneeded owner fieldRichard Purdie2007-02-20
| | | | | | | | | | | | Remove uneeded owner field from backlight_properties structure. Nothing uses it and it is unlikely that it will ever be used. The backlight class uses other means to ensure that nothing references unloaded code. Based on a patch from Dmitry Torokhov <dtor@insightbb.com> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

* ACPI: video: Add dev argument for backlight_device_registerYu Luming2006-12-20
| | | | | | | | | | | | | | | | | | | | | This patch set adds generic abstract layer support for acpi video driver to have generic user interface to control backlight and output switch control by leveraging the existing backlight sysfs class driver, and by adding a new video output sysfs class driver. This patch: Add dev argument for backlight_device_register to link the class device to real device object. The platform specific driver should find a way to get the real device object for their video device.

* ACPI: toshiba_acpi: Add support for the generic backlight deviceHolger Macht2006-10-21
| | | | | | | | | | | | | | | Add support for the generic backlight interface below /sys/class/backlight. Keep the procfs brightness handling for backward compatibility. To achive this, add two generic functions get_lcd and set_lcd to be used both by the procfs related and the sysfs related methods.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
