2010-02-28asus-laptop: code movementCorentin Chary
The asus-laptop driver implements a number of interfaces like the backlight class driver. This change makes it easier to examine the implementation of one interface at at a time, without having to search through the file to find init() and exit() functions etc. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28asus-laptop: callbacks should use "driver data" parameter or fieldCorentin Chary
(Changelog stolen from Alan's patch for eeepc-laptop, but this patch does the same thing for asus-laptop) Callback methods should not refer to a variable like "asus" (formally "hotk"). Instead, they should extract the data they need either from a "driver data" parameter, or the "driver data" field of the object which they operate on. The "asus" variable can then be removed. In practice, drivers under "drivers/platform" can get away without using driver data, because it doesn't make sense to have more than one instance of them. However this makes it harder to review them for correctness. This is especially true for core ACPI developers who have not previously been exposed to this anti-pattern :-). This will serve as an example of best practice for new driver writers (whether they find it themselves, or have it pointed out during review :-). Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28asus-laptop: move backlight and dsdt info inside asus_laptop structCorentin Chary
Prepare the use of "driver data" for callbacks. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28asus-laptop: revise namesCorentin Chary
asus-laptop now does a lot more than just hotkeys. Replace the "hotk" names used throughout the driver with some slightly more appropriate names. The actual strings used in kernel messages and sysfs are left unchanged. Signed-off-by: Corentin Chary <corentincj@iksaif.net>

2010-02-28asus-laptop: simplify write_acpi_intCorentin Chary
We only need a buffer for "INIT". Adds write_acpi_init_ret for it. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28asus-laptop: no need to check argument of set_brightness()Corentin Chary
We already tell the backlight class our maximum brightness value; it will validate the user requested values for us. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28asus-laptop: add wireless and bluetooth status parameterCorentin Chary
These to parameter allow to set the status of wlan and bluetooth device when the module load. On some models, the device will always be down on boot, so the default behavior is to always enable these devices. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2009-12-15asus-laptop: change light sens default values.Corentin Chary
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.

2009-12-09asus-laptop: add Lenovo SL hotkey supportIke Panhc
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>

2009-12-09asus-laptop: set acpi_driver.ownerAlan Jenkins
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:*.

2009-12-09asus-laptop: Remove redundant NULL checksAlan Jenkins
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>

2009-08-28asus-laptop: Add support for Keyboard backlightCorentin Chary
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.

2009-06-18ACPI: asus-laptop: use .notify method instead of installing handler directlyBjorn Helgaas
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.

2008-12-19create drivers/platform/x86/ from drivers/misc/Len Brown
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>
