2016-06-08thinkpad_acpi: Add support for HKEY version 0x200Dennis Wassenberg
Lenovo Thinkpad devices T460, T460s, T460p, T560, X260 use HKEY version 0x200 without adaptive keyboard. HKEY version 0x200 has method MHKA with one parameter value. Passing parameter value 1 will get hotkey_all_mask (the same like HKEY version 0x100 without parameter). Passing parameter value 2 to MHKA method will retrieve hotkey_all_adaptive_mask. If 0 is returned in that case there is no adaptive keyboard available.

A few recent regressions are fixed, most importantly in the cpuidle menu governor and in the ACPI backlight driver and some x86 platform drivers depending on it. Some more bugs are fixed and cleanups are made on top of that.

2015-05-20thinkpad_acpi: Revert unintentional device attribute renamingBjørn Mork
The conversion to DEVICE_ATTR_* macros failed to fixup a few cases where the old attribute names didn't match the show/store function names. Instead of renaming the functions, the attributes were renamed. This caused an unintentional API change. The hwmon required 'name' attribute were among the renamed attribute, causing libsensors to fail to detect the hwmon device at all. Fix by using the DEVICE_ATTR macro for these attributes, allowing the show/store functions to keep their system specific prefixes.

2014-12-04thinkpad-acpi: Try to use full software mute controlAndy Lutomirski
ThinkPads have hardware volume controls and three buttons to control them. (These are separate from the standard mixer.) By default, the buttons are: - Mute: Mutes the hardware volume control and, on some models, generates KEY_MUTE. - Up: Unmutes, generates KEY_VOLUMEUP, and increases volume if applicable. (Newer thinkpads only have hardware mute/unmute.) - Down: Unmutes, generates KEY_VOLUMEDOWN, and decreases volume if applicable. This behavior is unfortunate, since modern userspace will also handle the hotkeys and change the other mixer. If the software mixer is muted and the hardware mixer is unmuted and you push mute, hilarity ensues as they both switch state. Rather than adding a lot of complex ALSA integration to fix this, just disable the special ThinkPad volume controls when possible. This turns the mute and volume buttons into regular buttons, and standard software controls will work as expected. ALSA already knows about the mute light on models with a mute light, so everything should just work. This should also allow us to remove _OSI(Linux) for all ThinkPads. For future reference: It turns out that we can ask ACPI for one of three behaviors directly on very new models. They are "latch" (the default), "none" (no automatic control), and "toggle" (mute unmutes when muted). All of the modes besides "none" seem to be a bit buggy, though, and there doesn't seem to be a consistent way to get any notification when the HW mute state is changed.

The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

2014-04-06x86, acpi: LLVMLinux: Remove nested functions from Thinkpad ACPIBehan Webster
The only real change is passing in event_mask to the formerly nested functions. Otherwise it's just moving around function and macro code. This is the only place in the Linux kernel where nested functions are still in use. Nested functions aren't part of the C standards, and complicate the generated code. Although the Linux Kernel has never set out to be entirely C standard compliant, it is increasingly compliant to the standard which is supported by other compilers such as Clang. The LLVMLinux project is working on being able to compile the Linux kernel with Clang. The use of nested functions blocks this effort.

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.

2013-10-16thinkpad-acpi: fix handle locate for video and query of _BCLAaron Lu
The tpacpi_acpi_handle_locate function makes use of acpi_get_devices to locate handle for ACPI video by HID, the problem is, ACPI video node doesn't really have HID defined(i.e. no _HID control method is defined for video device), so.. that function would fail. This can be solved by enhancing the callback function for acpi_get_devices, where we can use acpi_device_hid function to check if the ACPI node corresponds to a video controller. In addition to that, the _BCL control method only exists under a video output device node, not a video controller device node. So to evaluate _BCL, we need the handle of a video output device node, which is child of the located video controller node from tpacpi_acpi_handle_locate. The two fix are necessary for some Thinkpad models to emit notification on backlight hotkey press as a result of evaluation of _BCL.
