2015-11-06thinkpad_acpi: Don't yell on unsupported brightness interfacesDavid Herrmann
The thinkpad_acpi driver currently emits error messages on unsupported brightness interfaces, giving the impression that someone will implement those. However, this error is spit out on nearly every thinkpad in production since 2 years now. Furthermore, the backlight interfaces on those devices are supported by the i915 driver just fine. Downgrade the error message to a normal pr_info() and stop telling people to report it to IBM.

2015-10-07platform/chrome: Make depends on MFD_CROS_EC instead CROS_EC_PROTOJavier Martinez Canillas
The ChromeOS EC LPC and chardev drivers depend on CROS_EC_PROTO but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since the platform devices that are matched with these drivers are registered by the ChromeOS EC mfd driver, they really depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the drivers to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

2015-10-06acer-wmi: remove threeg and interface sysfs interfacesLee, Chun-Yi
Since v3.0 kernel, acer-wmi driver auto detects internal 3G device and provides the threeg rfkill interface. So the sysfs interface of 3G is no longer necessary now. The 7b8aca65 patch added kernel information log to remind to user space for the threeg sysfs interface will be removed in 2012, then b58b9ffc patch updated the interface removing time to 2014. I think the 3 years lead time is enough for user space application to use rfkill instead of sysfs interface to control 3G device. This patch removes code about threeg sysfs interface. And it also removes the unused interface sysfs that exposes which ACPI-WMI method used by acer-wmi driver on the machine. The information is already exposed by the acer-wmi initial log.

2015-10-03platform/x86: Toshiba WMI Hotkey DriverAzael Avalos
Toshiba laptops that feature WMI events for hotkeys were left unsupported by the toshiba_acpi driver, however, commit a88bc06e5aec ("toshiba_acpi: Avoid registering input device on WMI event laptops") added hardware support for such laptops, but the hotkeys are not handled there. This driver adds support for hotkey monitoring on certain Toshiba laptops that manage the hotkeys via WMI events instead of the Toshiba Configuration Interface (TCI). The toshiba_acpi driver and this one can co-exist, as this only takes care of hotkeys, while the proper takes care of hardware related stuff. Currently the driver is under the EXPERIMENTAL flag, as the keymap and the notify function are incomplete (due to lack of hardware to test).

2015-09-10toshiba_acpi: Fix hotkeys registration on some toshiba modelsAzael Avalos
Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function for keymap choosing") changed the *setup_keyboard function to query for the Hotkey Event Type to help choose the correct keymap, but turns out that here are certain Toshiba models out there not implementing this feature, and thus, failing to continue the input device registration and leaving such laptops without hotkey support. This patch changes such check, and instead of returning an error if the Hotkey Event Type is not present, we simply inform userspace about it, changing the message printed from err to notice, making the function responsible for registering the input device to continue. This issue was found on a Toshiba Portege Z30-B, but there might be some other models out there affected by this regression as well.

2015-09-10wmi: Remove private %pUL implementationRasmus Villemoes
The work performed by wmi_gtoa is equivalent to simply sprintf(out, "%pUL", in), so one could replace its body by this. However, most users feed the result directly as a %s argument to some other function which also understands the %p extensions (they all ultimately use vsnprintf), so we can eliminate some stack buffers and quite a bit of code by just using %pUL directly. In wmi_dev_uevent I'm not sure whether there's room for a nul-terminator in env->buf, so I've just replaced wmi_gtoa with the equivalent sprintf call.

2015-08-28thinkpad_acpi: Remove side effects from vdbg_printk -> no_printk macroJoe Perches
vdbg_printk when not using CONFIG_THINKPAD_ACPI_DEBUG uses no_printk which produces no logging output but always evaluates arguments. Change the macro to surround the no_printk call with do { if (0) no_printk(...); } while (0) to avoid the unnecessary argument evaluations. $ size drivers/platform/x86/thinkpad_acpi.o* text data bss dec hex filename 60918 6184 824 67926 10956 drivers/platform/x86/thinkpad_acpi.o.new 60927 6184 824 67935 1095f drivers/platform/x86/thinkpad_acpi.o.old Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2015-08-26surface pro 3: Add support driver for Surface Pro 3 buttonsChen Yu
Since Surface Pro 3 does not follow the specs of "Windows ACPI Design Guide for SoC Platform", code in drivers/input/misc/soc_array.c can not detect these buttons on it. According to bios implementation, Surface Pro 3 encapsulates these buttons in a device named "VGBI", with _HID "MSHW0028". When any of the buttons is pressed, a specify ACPI notification code for this button will be delivered to "VGBI". For example, if power button is pressed down, ACPI notification code of 0xc6 will be sent by Notify(VGBI, 0xc6). This patch leverages "VGBI" to distinguish different ACPI notification code from Power button, Home button, Volume button, then dispatches these code to input layer. Lid is already covered by acpi button driver, so there's no need to rewrite.

2015-08-11mfd: watchdog: iTCO_wdt: Expose watchdog properties using platform dataMatt Fleming
Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across the SMBus, unlike previous generations of PCH/ICH where it was on the LPC bus. Because it's on the SMBus, it doesn't make sense to pass around a 'struct lpc_ich_info', and leaking the type of bus into the iTCO watchdog driver is kind of backwards anyway. This change introduces a new 'struct itco_wdt_platform_data' for use inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint code, which neatly avoids having to include lpc_ich headers in the i801 i2c driver. This change is overdue because lpc_ich_info has already found its way into other TCO watchdog users, notably the intel_pmc_ipc driver where the watchdog actually isn't on the LPC bus as far as I can see. A simple translation layer is provided for converting from the existing 'struct lpc_ich_info' inside the lpc_ich mfd driver.

2015-08-10ideapad-laptop: add alternative representation for Yoga 2 to DMI tableSebastian Krzyszkowiak
There is at least one (mine) Yoga 2 Pro in existence that has incorrect product version stored in DMI (reading as "INVALID"), causing it to not be recognized as Yoga 2 by ideapad-laptop module, which in turn causes non-existent hardware rfkills to be always reported as blocked. This change adds a second check by board name, which is "Yoga2". Looks like it also happens to be "INVALID" on some other Yoga 2 machines where product version is correct instead, so the original check is left intact to catch both cases.

2015-08-10asus-laptop: Add key found on Asus F3MŁukasz Stelmach
Asus F3M has two keys labeled with an icon of a touchpad. The first, reported as 0x6B is next to the power key and the second, reported as 0x6A, is F9 combined with Fn button. When I was pressing the latter, I was getting "Unknown key 6a pressed" message before applying this patch. Asus F3M does not support WMI so the commit does not update key mappings in the asus-nb-wmi.c file. I have not tested this mapping on any other Asus laptop.
