asus-laptop: add Lenovo SL hotkey support

2010-01-22T23:18:29Z

commit 14f8af311e7d3e4198cbaade84a34f86505dcb37 upstream. 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 Signed-off-by: Len Brown Signed-off-by: Greg Kroah-Hartman

acerhdf: limit modalias matching to supported

2010-01-06T23:03:28Z

commit bdc731bc5fcd1794e9ac8ac80c389d302381c123 upstream. BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958 The module alias currently matches any Acer computer but when loaded the BIOS checks will only succeed on Aspire One models. This causes a invalid BIOS warning for all other models (seen on Aspire 4810T). This is not fatal but worries users that see this message. Limiting the moule alias to models starting with AOA or DOA for Packard Bell.

asus-laptop: change light sens default values.

2009-12-18T22:05:34Z

commit d951d4cc84e8b5ddb8e0ab81cf6a72cc73fdd668 upstream. 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.

acerhdf: add new BIOS versions

2009-12-18T22:05:33Z

commit 360657463679dee44f0b167ffa61f563b4fee101 upstream. Added new BIOS versions for following netbooks: Acer 1410, Gateway LT31, Packard Bell DOA150. As the Gateway LT31 machines have different register values for setting and checking the off-state, the "cmd_off" variable has been splitted up to "cmd_off" and "chk_off".

thinkpad-acpi: preserve rfkill state across suspend/resume

2009-12-18T22:05:29Z

commit 208b996b6c460285650d39b2330f8ef82c007d10 upstream. Since the rfkill rework in 2.6.31, the driver is always resuming with the radios disabled. Change thinkpad-acpi to ask the firmware to resume with the radios in the last state. This fixes the Bluetooth and WWAN rfkill switches. Note that it means we respect the firmware's oddities. Should the user toggle the hardware rfkill switch on and off, it might cause the radios to resume enabled. UWB is an unknown quantity since it has nowhere the same level of firmware support (no control over state storage in NVRAM, for example), and might need further fixing. Testers welcome. This change fixes a regression from 2.6.30.

thinkpad-acpi: fix default brightness_mode for R50e/R51

2009-12-18T22:05:28Z

commit a9f8eacca4e9e8693de9b896c1fa7aadaa9402e8 upstream. According to a report, the R50e wants EC-based brightness control, even if it uses an Intel GPU. The current driver default was reported to not work at all. This bug can be worked around by the "brightness_mode=3" module parameter. Change the default of the R50e and R51 2xxx models (which use the same EC firmware, 1V) to TPACPI_BRGHT_Q_EC, but keep TPACPI_BRGHT_Q_ASK set for now, as I'd like to get more reports. This fixes a regression caused by commit 59fe4fe34d7afdf63208124f313be9056feaa2f4, "thinkpad-acpi: fix incorrect use of TPACPI_BRGHT_MODE_ECNVRAM" Kernel 2.6.31 also needs this fix.

thinkpad-acpi: fix detection of old ThinkPads

2009-11-25T05:42:15Z

There is a problem in the quirk tables used by tpacpi_is_fw_known() and tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking the EC firmware ID DMI field to never match. This breaks module loading on, e.g. a T23 with outdated BIOS, and the module will refuse to load unless the "force_load=1" parameter is given. Fix the quirk tables so that they can also match the outdated BIOSes, which in turn will both fix the module loading, and also warn the user that he is using outdated firmware and should upgrade. This fixes a serious regression, introduced by commit e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict when detecting a ThinkPad". http://bugzilla.kernel.org/show_bug.cgi?id=14597 Reported-by: Paul Kimoto Signed-off-by: Henrique de Moraes Holschuh Tested-by: Paul Kimoto Signed-off-by: Andrew Morton Signed-off-by: Len Brown
