| * hp-wmi: Enable hotkeys on some systemsKyle Evans2014-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a third attempt to enable these buttons. The new variable being commit 997daa1bd9aca412ab97955a35b26c460c0ec7a4 (i.e. hp-wmi: detect "2009 BIOS or later"). Older systems that do not have the 2009 BIOS query method respond with a dummy value, in this case 4. Using that, we can target a fairly narrow group of systems. i.e. old enough to not have HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9. This group may be further limited if some systems respond with something other than 4 to non-existant feature queries.

| * thinkpad_acpi: Add mappings for F9 - F12 hotkeys on X240 / T440 / T540Hans de Goede2014-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12 keys should be mapped to: control-panel, search, show-all-windows and Computer. These keys generate the sofar unused 28 - 31 hotkey scancodes. For the first 2 this nicely matches the icons on the keys, for the latter 2 the icons are somewhat creative, which is why I ended up looking them up in the user manual.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've observed the missing pvpanic call at panic, and it turned out that this was blocked by the broken notifier of drm_fb_helper, where scheduling may be called during switching to the fb console. It's fairly difficult to fix the drm_fb problem and a quick fix isn't foreseen, a simpler solution for the missing pvpanic call would be just to call this earlier. In order to assure that, this patch sets a higher priority to pvpanic notifier_block. Once when the issue of drm_fb is resolved, we can remove this priority again.

Allowing a keycode array of up to 8 items is simpler and more generic. So replace #define with configurable number of keys which also allows the removal of is_tp. * Rename platform data parameters to include "t19" to prevent confusion with T15 key array. * Probe aborts early on when pdata is NULL, so no need to check. * Move "int i" to beginning of function (mixed declarations and code) * Use API calls rather than __set_bit() * Remove unused dev variable.

| * Input: atmel_mxt_ts - remove unnecessary platform dataNick Dyer2014-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not necessary to download these values to the maXTouch chip on every probe, since they are stored in NVRAM. It makes life difficult when tuning the device to keep them in sync with the config array/file, and requires a new kernel build for minor tweaks. These parameters only represent a tiny subset of the available configuration options, tracking all of these options in platform data would be a endless task. In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all. Having these values also makes life more complex for device tree and other platforms where having to define a static configuration isn't helpful.

We have no major new features this time, but there are a few significant changes of how things work. The most visible one will probably be that we are now going to create platform devices rather than PNP devices by default for ACPI device objects with _HID. That was long overdue and will be really necessary to be able to use the same drivers for the same hardware blocks on ACPI and DT-based systems going forward. We're not expecting fallout from this one (as usual), but it's something to watch nevertheless. The second change having a chance to be visible is that ACPI video will now default to using native backlight rather than the ACPI backlight interface which should generally help systems with broken Win8 BIOSes. We're hoping that all problems with the native backlight handling that we had previously have been addressed and we are in a good enough shape to flip the default, but this change should be easy enough to revert if need be. In addition to that, the system suspend core has a new mechanism to allow runtime-suspended devices to stay suspended throughout system suspend/resume transitions if some extra conditions are met (generally, they are related to coordination within device hierarchy). However, enabling this feature requires cooperation from the bus type layer and for now it has only been implemented for the ACPI PM domain (used by ACPI-enumerated platform devices mostly today). Also, the acpidump utility that was previously shipped as a separate tool will now be provided by the upstream ACPICA along with the rest of ACPICA code, which will allow it to be more up to date and better supported, and we have one new cpuidle driver (ARM clps711x). The rest is improvements related to certain specific use cases, cleanups and fixes all over the place. Specifics: - ACPICA update to upstream version 20140424. That includes a number of fixes and improvements related to things like GPE handling, table loading, headers, memory mapping and unmapping, DSDT/SSDT overriding, and the Unload() operator. The acpidump utility from upstream ACPICA is included too. From Bob Moore, Lv Zheng, David Box, David Binderman, and Colin Ian King. - Fixes and cleanups related to ACPI video and backlight interfaces from Hans de Goede. That includes blacklist entries for some new machines and using native backlight by default. - ACPI device enumeration changes to create platform devices rather than PNP devices for ACPI device objects with _HID by default. PNP devices will still be created for the ACPI device object with device IDs corresponding to real PNP devices, so that change should not break things left and right, and we're expecting to see more and more ACPI-enumerated platform devices in the future. From Zhang Rui and Rafael J Wysocki. - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it to handle system suspend/resume on Asus T100 correctly. From Heikki Krogerus and Rafael J Wysocki. - PM core update introducing a mechanism to allow runtime-suspended devices to stay suspended over system suspend/resume transitions if certain additional conditions related to coordination within device hierarchy are met. Related PM documentation update and ACPI PM domain support for the new feature. From Rafael J Wysocki. - Fixes and improvements related to the "freeze" sleep state. They affect several places including cpuidle, PM core, ACPI core, and the ACPI battery driver.

| * | acer-wmi: Switch to acpi_video_unregister_backlightHans de Goede2014-05-20

Since there are no mappings for the atkbd raw codes for the brightness keys used by newer Acer models in /lib/udev/hwdb.d/60-keyboard.hwdb, and since we map the wmi events with a code of KE_IGNORE, we rely on acpi-video to do the hotkey handling for us. For laptops such as the Acer Aspire 5750 which uses intel gfx this works despite us calling acpi_video_unregister() because the following happens: 1) acpi-video module gets loaded (as it is a dependency of acer-wmi and i915) 2) acpi-video does NOT call acpi_video_register() 3) acer-wmi loads (assume it loads before i915), calls acpi_video_dmi_promote_vendor(); which sets ACPI_VIDEO_BACKLIGHT_DMI_VENDOR 4) calls acpi_video_unregister -> not registered, nop 5) i915 loads, calls acpi_video_register 6) acpi_video_register registers the acpi_notifier for the hotkeys, does NOT register a backlight device because of ACPI_VIDEO_BACKLIGHT_DMI_VENDOR But on the Acer Aspire 5750G, which uses nvidia graphics the following happens: 1) acpi-video module gets loaded (as it is a dependency of acer-wmi) 2) acpi-video calls acpi_video_register() 3) acpi_video_register registers the acpi_notifier for the hotkeys, and a backlight device 4) acer-wmi loads, calls acpi_video_dmi_promote_vendor() 5) calls acpi_video_unregister, this unregisters BOTH the acpi_notifier for the hotkeys AND the backlight device And we end up without any handler for the brightness hotkeys. This patch fixes this by switching over to acpi_video_unregister_backlight() which keeps the hotkey handler in place.

Lots of stuff here, tons of cleanup patches, a few new drivers, and some removed as well, but I think we are still adding a few thousand more lines than we remove, due to the new drivers being bigger than the ones deleted. One notible bit of work did stand out, Jes Sorensen has gone on a tear, fixing up a wireless driver to be "more sane" than it originally was from the vendor, with over 500 patches merged here. Good stuff, and a number of users laptops are better off for it.

* x86, acpi: LLVMLinux: Remove nested functions from Thinkpad ACPIBehan Webster2014-04-06
| | | | | | | | | | | | | | | | | | | | | | | 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.

* toshiba_acpi: Add accelerometer supportAzael Avalos2014-04-06
| | | | | | | | | | | | | Recent Toshiba laptops now come equiped with a built in accelerometer (TOS620A) device, but such device does not expose the axes information, however, HCI calls 0x006d and 0x00a6 can be used to query such info. This patch adds support to read the axes values by exposing them through the _position_ sysfs file.

* toshiba_acpi: Add ECO mode led supportAzael Avalos2014-04-06
| | | | | | | | | | | | | Newer Toshiba laptops now come with a feature called ECO Mode, where the system is put in low power consupmtion state and a green (world shaped with leaves) icon illuminates indicating that the system is in such power state. This patch adds support to turn on/off the ECO led by creating and registering the toshiba::eco_mode led.

* toshiba_acpi: Add touchpad enable/disable support-Azael Avalos2014-04-06
| | | | | | | | | | | | | | | | Toshiba laptops have two ways of letting userspace know the touchpad has changed state, one with a button on top of the touchpad that simply emmits scancodes whenever enabled/disabled, and another one by pressing Fn-F9 (touchpad toggle) hotkey. This patch adds support to enable/disable the touchpad by exposing the _touchpad_ file in sysfs that simply makes a call to a SCI register, imitating what Toshiba provided software does on Windows.

* toshiba_acpi: Add keyboard backlight supportAzael Avalos2014-04-06
| | | | | | | | | | | | | | | | | | | | | | Toshiba laptops equiped with an illuminated keyboard can operate in two different modes: Auto and FN-Z. The Auto mode turns on the led on keystrokes and automatically turns it off after some (configurable) time the last key was pressed. The FN-Z mode is used to toggle the keyboard led on/off by userspace. This patch adds support to set the desired KBD mode and timeout via sysfs, creates and registers toshiba::kbd_backlight led device whenever the mode is set to FN-Z. The acceptable values for mode are: 1 (Auto) and 2 (Fn-Z) The time values range are: 1-60 seconds Signed-off-by: Azael Avalos <coproscefalo@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
