* asus-laptop: change light sens default values.Corentin Chary2009-12-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The light sensor disable brightness key and /sys/class/backlight/ control. There was a lot of report from users who didn't understand why they couldn't change their brightness, including: https://bugs.launchpad.net/bugs/222171 https://bugzilla.novell.com/show_bug.cgi?id=514747 http://bugzilla.kernel.org/show_bug.cgi?id=13671 http://bugzilla.kernel.org/show_bug.cgi?id=14432 Now the light sensor is disabled, and if the user want to enable it, the level should be ok. The funny thing is that comments where ok, not code.

* asus-laptop: add Lenovo SL hotkey supportIke Panhc2009-12-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lenovo SL series laptop has a very similar DSDT with Asus laptops. We can easily have the extra ACPI function support with little modification in asus-laptop.c Here is the hotkey enablement for Lenovo SL series laptop. This patch will enable the following hotkey: - Volumn Up - Volumn Down - Mute - Screen Lock (Fn+F2) - Battery Status (Fn+F3) - WLAN switch (Fn+F5) - Video output switch (Fn+F7) - Touchpad switch (Fn+F8) - Screen Magnifier (Fn+Space) The following function of Lenovo SL laptop is still need to be enabled: - Hotkey: KEY_SUSPEND (Fn+F4), KEY_SLEEP (Fn+F12), Dock Eject (Fn+F9) - Rfkill for bluetooth and wlan - LenovoCare LED - Hwmon for fan speed - Fingerprint scanner - Active Protection System Signed-off-by: Ike Panhc <ike.pan@canonical.com> Signed-off-by: Len Brown <len.brown@intel.com>

* asus-laptop: set acpi_driver.ownerAlan Jenkins2009-12-091-0/+1
| | | | | | | | | | | | The owner field provides the link between drivers and modules in sysfs, but no ACPI driver was setting it. After setting the owner field, we can see which module provides which driver and vice versa by looking at /sys/bus/acpi/driver/*/module and /sys/module/*/drivers/acpi:*.

* asus-laptop: Remove uneccesary acpi_disabled checkAlan Jenkins2009-12-091-3/+0
| | | | | | | | acpi_bus_register_driver() already checks acpi_disabled, so acpi bus drivers don't need to. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>
* asus-laptop: Remove redundant NULL checksAlan Jenkins2009-12-091-6/+0
| | | | | | | | | | | | | | | | | | | | | | | The acpi device callbacks add, start, remove, suspend and resume can never be called with a NULL acpi_device. Each callsite in acpi/scan.c has to dereference the device in order to get the ops structure, e.g. struct acpi_device *acpi_dev = to_acpi_device(dev); struct acpi_driver *acpi_drv = acpi_dev->driver; if (acpi_drv && acpi_drv->ops.suspend) return acpi_drv->ops.suspend(acpi_dev, state); Remove all checks for acpi_dev == NULL within these callbacks. Also remove the checks for acpi_driver_data(acpi_dev) == NULL. None of these checks could fail unless the driver does something strange (which none of them do), the acpi core did something terribly wrong, or we have a memory corruption issue. If this does happen then it's best to dereference the pointer and crash noisily. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>

* asus-laptop: Add support for Keyboard backlightCorentin Chary2009-08-281-2/+77
| | | | | | | | | | | | | | | | | | | Add support for keyboard backlight found in Asus U50VG. The SMC driver for the Apples does it via LED. To be consistent with that we create /sys/class/leds/asus::kbd_backlight/ to control the keyboard backlight. SLKB and GLKB are used to get/set the backlight. On the U50VG is supports 4 brightness level, but this may change with other models. SLKB take a 8 bit integer where the higher bit is used to toggle the backlight, and the over 7 bits control the brightness level.

* ACPI: asus-laptop: use .notify method instead of installing handler directlyBjorn Helgaas2009-06-181-18/+5
| | | | | | | | | | | | | | | This patch adds a .notify() method. The presence of .notify() causes Linux/ACPI to manage event handlers and notify handlers on our behalf, so we don't have to install and remove them ourselves. This driver apparently relies on seeing ALL notify events, not just device-specific ones (because it used ACPI_ALL_NOTIFY). We use the ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag to request all events.

* create drivers/platform/x86/ from drivers/misc/Len Brown2008-12-191-0/+1266
Move x86 platform specific drivers from drivers/misc/ to a new home under drivers/platform/x86/. The community has been maintaining x86 vendor-specific platform specific drivers under /drivers/misc/ for a few years. The oldest ones started life under drivers/acpi. They moved out of drivers/acpi/ because they don't actually implement the ACPI specification, but either simply use ACPI, or implement vendor-specific ACPI extensions. In the future we anticipate... drivers/misc/ will go away. other architectures will create drivers/platform/<arch> Signed-off-by: Len Brown <len.brown@intel.com>
