surface pro 4: Add support for Surface Pro 4 Buttons

2016-01-20T01:35:52Z

Surface Pro 4 buttons are managed by a device with _HID "MSHW0040" different from Surface Pro 3. This commit adds MSHW0040 to id list to support the Surface Pro 4. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=109871 Signed-off-by: Weng Xuetian Acked-by: Chen Yu Signed-off-by: Darren Hart

platform/x86: Add Intel Telemetry Core Driver

2016-01-20T01:35:50Z

Intel PM Telemetry is a software mechanism via which various SoC PM and performance related parameters like PM counters, firmware trace verbosity, the status of different devices inside the SoC, etc. can be monitored and analyzed. The different samples that may be monitored can be configured at runtime via exported APIs. This patch adds the telemetry core driver that implements basic exported APIs.

platform/x86: Add Asus Wireless Radio Control driver

2016-01-20T01:35:46Z

Some Asus notebooks like the Asus E202SA and the Asus X555UB have a separate ACPI device for notifications from the airplane mode hotkey. This device is called "Wireless Radio Control" in Asus websites and ASHS in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned above. For these models, when the airplane mode hotkey (Fn+F2) is pressed, a query 0x0B is started in the Embedded Controller, and all this query does is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"): Scope (_SB.PCI0.SBRG.EC0) { (...) Method (_Q0B, 0, NotSerialized) // _Qxx: EC Query { If ((MSOS () >= OSW8)) { Notify (ASHS, 0x88) // Device-Specific } Else { (...) } } } Signed-off-by: João Paulo Rechi Vita Reviewed-by: Andy Shevchenko Signed-off-by: Darren Hart

platform/x86: Add rfkill dependency to ACPI_TOSHIBA entry

2016-01-19T23:49:37Z

Commit 2fdde83443aa ("toshiba_acpi: Add WWAN RFKill support") added WWAN rfkill support to the driver, but the KConfig entry was not updated to add the RFKill dependency, causing a broken build if RFKill is not selected. This patch adds the RFKILL dependency to the KConfig entry, fixing the build issue. Signed-off-by: Azael Avalos Signed-off-by: Darren Hart

ideapad-laptop: add support for Yoga 3 ESC key

2015-11-09T21:23:10Z

The ideapad-laptop handles most special keys on various Lenovo Laptops including the Yoga line. Unfortunately, the Yoga 3 11/13/14 models have one important exception, which is the Fn-ESC combination. On other Lenovo Laptops, this is FnLock, which switches the function keys between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1, F2, F3, ...) behavior. On the new machines, FnLock is only available through BIOS setup (possibly through a yet-to-be-implemented feature in this driver) but not through Fn-ESC, but instead the ESC key itself switched between ESC and a "Paper Display" app for Windows. Unfortunately, that means that you can never have both ESC *and* the function keys working at the same time without needing to press Fn on one of them. As pointed out in the official Lenovo Forum by dozens of users, this makes the machine rather useless for any serious work [1]. I have now studied the ACPI DSDT one more time and found the event that is generated for the ESC key. Unlike all other key events on this machine, it is actually a WMI, while the other ones are read from the embedded controller. I am now installing a WMI notifier that uses the event number from the WMI subsystem as the scancode. The only event number generated here is '128', and that fits in nicely with the two existing ranges of scancodes used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS. The only sane way to handle this button (in absence of the Windows Paper Display driver) seems to be to have it emit KEY_ESC, so that is what I use as the default. Should any user ever want to overwrite the default, they can install their own keymap. To ensure that we can still build the driver without adding a CONFIG_WMI dependency, all new code is enclosed in #ifdef.
