2010-03-01toshiba-acpi: fix multimedia keys on some machinesFrans Pop
Some Toshibas only send ACPI events on key down, not key release. Ignore any release events and send key down and key up events on every ACPI key down event. Signed-off-by: Frans Pop <elendil@planet.nl>
2010-03-01dell-laptop: Fix errors on failure and exit pathsMatthew Garrett
Make sure that work is cancelled after removing the i8042 filter, and unregister the platform device rather than deleting it. Signed-off-by: Matthew Garrett <mjg@redhat.com> Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2010-03-01dell-laptop: Fix build error by making buffer_mutex staticIngo Molnar
The following build bug (x86, allyesconfig): arch/x86/oprofile/built-in.o:(.data+0x250): multiple definition of `buffer_mutex' Was triggered in -tip testing, caused by this upstream commit: 116ee77: dell-laptop: Use buffer with 32-bit physical address There's multiple buffer_mutex's in the kernel. Make this new one static. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2010-02-28asus-laptop: use device_create_file() instead of platform_groupCorentin Chary
There is two reason to do that: - we don't want a "gps" file if the model doesn't have a gps - we don't want to use global variables anymore Signed-off-by: Corentin Chary <corentincj@iksaif.net>

The rfkill subsystem will enable gps by default. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28asus-laptop: set initial lcd stateCorentin Chary
There is no way to find the initial lcd state. A quick workaround is to set it "on" by default. Anyway this feature is scheduled for removal. Signed-off-by: Corentin Chary <corentin.chary@gmail.com>

2010-02-28asus-laptop: add backlight changes notificationsCorentin Chary
We don't want to send KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP because it would be a lie to tell userspace that we want to change the brightness while it's actually done by the firmware. Signed-off-by: Corentin Chary <corentincj@iksaif.net>

2010-02-28asus-laptop: stop using ASUS_HANDLE and use relative methods insteadCorentin Chary
Stop using ASUS_HANDLE because most of the time it is not needed. This macro was introduced to display_get and lcd_switch which are not part of the interface provided by Asus, and are scheduled for removal. Signed-off-by: Corentin Chary <corentincj@iksaif.net>

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>
2010-02-28eeepc-laptop: check wireless hotplug eventsAlan Jenkins
Before we mark the wireless device as unplugged, check PCI config space to see whether the wireless device is really disabled (and vice versa). This works around newer models which don't want the hotplug code, where we end up disabling the wired network device. My old 701 still works correctly with this. I can also simulate an afflicted model by changing the hardcoded PCI bus/slot number in the driver, and it seems to work nicely (although it is a bit noisy). In future this type of hotplug support will be implemented by the PCI core. The existing blacklist and the new warning message will be removed at that point.

2010-02-28eeepc-laptop: disable wireless hotplug for 1005PEAlan Jenkins
The wireless hotplug code is not needed on this model, and it disables the wired ethernet card. (Like on the 1005HA and 1201N).

2010-02-25toshiba_acpi: Add full hotkey supportMatthew Garrett
Calling the ENAB method on Toshiba laptops results in notifications being sent when laptop hotkeys are pressed. This patch simply calls that method and sets up an input device if it's successful.

2010-02-25dell-laptop: Add another Dell laptop to the DMI whitelistErik Andren
The Latitude C640 has another variation of dell in its DMI vendor entry. Add it to the whitelist in order to enjoy the sweet fruits of software backlight toggling. Signed-off-by: Erik Andren <erik.andren@gmail.com>
2010-02-25classmate-laptop: use a single MODULE_DEVICE_TABLE to get correct aliasesThadeu Lima de Souza Cascardo
Instead of a MODULE_DEVICE_TABLE for every acpi_driver ids table, we create a table containing all ids to export to get a module alias for each one. This will fix automatic loading of the driver when one of the ACPI devices is not present (like the accelerometer, which is not present in some models). Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com>
2010-02-25dell-laptop: Pay attention to which devices the hardware switch controlsMatthew Garrett
Right now, we assume that the hardware rfkill switch on Dells toggles all radio devices. In fact, this can be configured in the BIOS and so right now we may mark a device as hardware killed even when it isn't. Add code to query the devices controlled by the switch, and use this when determining the hardware kill state of a radio. Signed-off-by: Matthew Garrett <mjg@redhat.com>
2010-02-25dell-laptop: Use buffer with 32-bit physical addressStuart Hayes
Calls to communicate with system firmware via a SMI (using dcdbas) need to use a buffer that has a physical address of 4GB or less. Currently the dell-laptop driver does not guarantee this, and when the buffer address is higher than 4GB, the address is truncated to 32 bits and the SMI handler writes to the wrong memory address.

2010-02-25dell-laptop: Block software state changes when rfkill hard blockedMario Limonciello
The "hardware" switch is tied directly to a BIOS interface that will connect and disconnect the hardware from the bus. If you use the software interface to request the BIOS to make these changes, the HW switch will be in an inconsistent state and LEDs may not reflect the state of the HW.

2010-02-25dell-laptop: Update rfkill state on kill switchMatthew Garrett
The rfkill interface on Dells only sends a notification that the switch has been changed via the keyboard controller. Add a filter so we can pick these notifications up and update the rfkill state appropriately. Signed-off-by: Matthew Garrett <mjg@redhat.com>
2010-02-25compal-laptop: Replace sysfs support with rfkill supportMario Limonciello
