2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

2012-03-26asus-wmi: store backlight power status for AIO machineAceLan Kao
Due to some implementation reasons, ASUS ET2012 All-in-One machines can't report the correct backlight power status, it will always return 1. To track the backlight power status correctly, we have to store the status by ourselves. BTW, by the BIOS design, the backlight power will be turn on/off sequently, no matter what the value of the parameter will be. More over, the brightness adjustment command will turn on the backlight power. Those behaviors will make us fail to track the backlight power status. For example, While we are trying to turn on the backlight power, we will send out the brightness adjustment command and then trying to figure out if we have to turn on the backlight power, then send out the command. But, the real case is that, the backlight power turns on while sending the brightness adjustment command, and then we send out the command to turn on the backlight power, it actually will turn off the backlight power and the backlight power status we recorded becomes wrong. So, we have to seperate these two commands by a if statement.

2012-03-26asus-wmi: add scalar board brightness adj. supportAceLan Kao
Some ASUS ET2012E/I All-in-One machines that use a scalar board to control the brightness, and they only accept brightness up and down command. So, I introduced a get_scalar_command() function to pass the command to the scalar board through WMI. Besides, we have to store the brightness value locally, for we need the old value to know the brightness value is increasing or decreasing. BTW, since there is no way to retrieve the actual brightness(it would be a fixed value), and the max brightness value would be fixed to 1, so we have to keep passing the brightness up/down command when we reached the max brightness value or 0.

2011-08-05eeepc-wmi: Add support for T101MT Home/Express Gate keySeth Forshee
This key is different than other hotkeys, having seperate scan codes for press, release, and hold, so it requires some special filtering. Press and release events are passed on, and hold events are ignored since sparse-keymap does not support hardware autorepeat. Note that "Home" in the context of this button doesn't mean the same thing as the usual Home key, and it really isn't clear at all what is meant by "Home". The manufacurer's description of the button indicates that it should launch some sort of touch screen settings interface on short press and apply a desktop rotation on long press.

2011-03-28eeepc-wmi: asus generic asus-wmi.ko moduleCorentin Chary
New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.

2011-03-28eeepc-wmi: serialize access to wmi methodCorentin Chary
\AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...

2011-03-28eeepc-wmi: add hotplug code for Eeepc 1000HCorentin Chary
Implement wireless like hotplug handling (code stolen from eeepc-laptop). Reminder: on some models rfkill is implemented by logically unplugging the wireless card from the PCI bus. Despite sending ACPI notifications, this does not appear to be implemented using standard ACPI hotplug - nor does the firmware provide the _OSC method required to support native PCIe hotplug. The only sensible choice appears to be to handle the hotplugging directly in the platform driver. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2010-10-21eeepc-wmi: Add cpufv sysfs interfaceChris Bagwell
eeepc-laptop provides a sysfs interface to read and control what it calls cpufv. When WMI is enabled, the ACPI interface changes slightly and becames a write-only control with 3 valid values. Expose cpufv again to allow for user space utils that can extended battery life noticably and come a little closer to parity with eeepc-laptop. Write-only is OK for most user space apps because read status was mostly used to prevent unneeded mode changes. Since this same check to ignore changes to same mode also exists in the DSDT then it was wasted ACPI call. acpi_osi="!Windows 2009" can be used for get back eeepc-laptop's read support of cpufv for debugging things such as behaviour during resume. This patch was tested with EEE PC 1005PE by monitoring powertop output while writing values of "0", "1", and "2" and by reviewing the decompiled DSDT of an 1201NL and comparing it to 1005PE's DSDT.
