2017-01-22platform/x86: ideapad-laptop: handle ACPI event 1Zach Ploskey
On Ideapad laptops, ACPI event 1 is currently not handled. Many models log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while running on battery power. Some convertible laptops receive this event when switching in and out of tablet mode. This adds and additional case for event 1 in ideapad_acpi_notify to call ideapad_input_report(priv, vpc_bit), so that the event is reported to userspace and we avoid unnecessary logging. Fixes bug #107481 (https://bugzilla.kernel.org/show_bug.cgi?id=107481) Fixes bug #65751 (https://bugzilla.kernel.org/show_bug.cgi?id=65751) Signed-off-by: Zach Ploskey <zach@ploskey.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

2016-12-28platform/x86: fujitsu-laptop: use brightness_set_blocking for LED-setting ↵Micha? K?pie?
callbacks All LED-setting functions in fujitsu-laptop are currently assigned to the brightness_set callback, which is incorrect because they can sleep (due to their use of call_fext_func(), which in turn issues ACPI calls) and the documentation (in include/linux/leds.h) clearly states they must not. Assign them to brightness_set_blocking instead and change them to match the expected function prototype. This change makes it possible to use Fujitsu-specific LEDs with "heavy" triggers, like disk-activity or phy0rx.

2016-12-16platform/x86: Introduce button support for the Surface 3Benjamin Tissoires
The Surface 3 is not following the ACPI spec for PNP0C40, but nearly. The device is connected to a I2C device that might have some magic but we don't know about. Just create the device after the enumeration and use the declared GPIOs to provide button support. This driver is just an adaptation of drivers/input/misc/soc_button_array.c The Surface Pro 3 is using an ACPI driver and matches against the bid of the device ("VGBI"). To prevent this incompatible driver to be used on the Surface Pro, we add a match on the Surface 3 bid "TEV2". link: https://bugzilla.kernel.org/show_bug.cgi?id=102761 Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2016-12-16platform/x86: Add custom surface3 platform device for controlling LIDBenjamin Tissoires
The LID state provided by ACPI on the Surface 3 is not accurate. The ACPI node doesn't get notified on LID open, which means the LID input switch stays close most of the time. Fortunatelly, there is a WMI method which directly queries the GPIO underneath the LID state, so it's far more reliable than ACPI. To get the notifications that the LID was opened/closed, we can rely on the ACPI notification of the touchscreen: the DSDT shows that the touchscreen will get notified on close/open as it also controls its _STA method. Note that we need to set the tag "power-switch" to the LID input node through a udev rule for logind to accept it: SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="surface3-wmi", \ TAG+="power-switch" Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

The hotkey events and ACPI handles used for detecting tablet mode on a few of the newer thinkpad models (Yoga X1 and the Yoga 260 specifically) have been changed around, so unfortunately this means we're definitely going to need to probe for multiple types of tablet mode support. Since the hotkey_init() is already a lot larger than it should be, let's split up this detection into its own function to make things a little easier to read. As well, since we're going to have multiple types of tablet modes, make hotkey_tablet into an enum so we can also use it to indicate the type of tablet mode reporting the machine supports.

On SPT, in addition to the crystal oscillator clock, the 100Mhz Gen2 USB3PCI2 PLL clock is used as the PLL reference clock and Gen2 PLL idling is a necessary condition for the platform to go into low power states like PC10 and S0ix.

2016-12-13platform/x86: intel_pmc_core: ModPhy core lanes pg statusRajneesh Bhardwaj
The PCH implements a number of High Speed I/O (HSIO) lanes that are split between PCIe*, USB 3.0, SATA, GbE, USB OTG and SSIC. This patch shows the current power gating status of the available ModPhy Core lanes. This is done by sending a message to the PMC (MTPMC) that contains the XRAM register offset for the MPHY_CORE_STS_0 and MPHY_CORE_STS_1 and then by reading the response sent by the PMC (MFPMC). While enabling low power modes we often encounter situations when the ModPhy lanes are not power gated and it becomes hard to debug which lane is active and which is not in the absence of an external hardware debugger (JTAG/ITP). This patch eliminates the dependency on an external hardware debugger for reading the ModPhy Lanes power gating status. This patch requires PMC_READ_DISABLE setting to be disabled in the platform bios. cat /sys/kernel/debug/pmc_core/mphy_lanes_power_gating_status Signed-off-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@intel.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2016-12-13platform/x86: intel_pmc_core: Add PCH IP Power Gating StatusRajneesh Bhardwaj
This patch adds the support for reading the power gating status of various devices present on Sunrise Point PCH. This is intended to be used for debugging purpose while tuning the platform for power optimizations and also to understand which devices (on PCH) are blocking the system to enter a low power state. Power Management Controller on Sunrise Point PCH provides access to "PGD PFET Enable Ack Status Registers (ppfear)". This patch reads and decodes this register and dumps the output in formatted manner showing various devices present on the PCH and their "Power Gating" status. Further documentation can be found in Intel 7th Gen Core family mobile u/y processor io datasheet volume 2. Sample output (stripped and not in order): cat /sys/kernel/debug/pmc_core/pch_ip_power_gating_status PMC State: Not Power gated OPI-DMI State: Not Power gated XHCI State: Power gated LPSS State: Power gated CSME_PSF State: Not power gated Signed-off-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@intel.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>

2016-12-13platform/x86: acer-wmi: Only supports AMW0_GUID1 on acer familyLee, Chun-Yi
The AMW0_GUID1 wmi is not only found on Acer family but also other machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled those non-Acer machines by quirks list. But actually acer-wmi driver was loaded on any machine that had AMW0_GUID1. This behavior is strange because those machines should be supported by appropriate wmi drivers. e.g. fujitsu-laptop, ideapad-laptop. This patch adds the logic to check the machine that has AMW0_GUID1 should be in Acer/Packard Bell/Gateway white list. But, it still keeps the quirk list of those supported non-acer machines for backward compatibility.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c, that need to pass extra build-in properties to the devices they create. Previously the drivers added those properties to the struct device which is member of the struct acpi_device, but that does not work. Those properties need to be assigned to the struct device of the platform device instead in order for them to become available to the drivers. To fix this, this patch changes acpi_create_platform_device function to take struct property_entry pointer as parameter.
