| * | asus-wireless: Toggle airplane mode LEDJoão Paulo Rechi Vita2016-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the ASHS device we have the HSWC method, which calls either OWGD or OWGS, depending on its parameter: Device (ASHS) { Name (_HID, "ATK4002") // _HID: Hardware ID Method (HSWC, 1, Serialized) { If ((Arg0 < 0x02)) { OWGD (Arg0) Return (One) } If ((Arg0 == 0x02)) { Local0 = OWGS () If (Local0) { Return (0x05) } Else { Return (0x04) } } If ((Arg0 == 0x03)) { Return (0xFF) } If ((Arg0 == 0x04)) { OWGD (Zero) Return (One) } If ((Arg0 == 0x05)) { OWGD (One) Return (One) } If ((Arg0 == 0x80)) { Return (One) } } Method (_STA, 0, NotSerialized) // _STA: Status { If ((MSOS () >= OSW8)) { Return (0x0F) } Else { Return (Zero) } } } On the Asus laptops that do not have an airplane mode LED, OWGD has an empty implementation and OWGS simply returns 0. On the ones that have an airplane mode LED these methods have the following implementation: Method (OWGD, 1, Serialized) { SGPL (0x0203000F, Arg0) SGPL (0x0203000F, Arg0) } Method (OWGS, 0, Serialized) { Store (RGPL (0x0203000F), Local0) Return (Local0) } Where OWGD(1) sets the airplane mode LED ON, OWGD(0) set it off, and OWGS() returns its state. This commit exposes the airplane mode indicator LED to userspace under the name asus-wireless::airplane, so it can be driven according to userspace's policy.

| * | fujitsu-laptop: Support touchpad toggle hotkey on Skylake-based modelsMichał Kępień2016-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Haswell-based Fujitsu laptops (Lifebook E734/E744/E754) have a touchpad toggle hotkey (Fn+F4) which is handled transparently to the operating system: while an ACPI notification is sent to FUJ02B1 when Fn+F4 is pressed, touchpad state is properly toggled without any explicit support for this operation in fujitsu-laptop. Skylake-based models (Lifebook E736/E746/E756) also have that hotkey, but the touchpad is not toggled transparently to the operating system. When Fn+F4 is pressed, an ACPI notification is sent to FUJ02E3. A subsequent call to S000 (FUNC_RFKILL) can be used to determine whether the touchpad toggle hotkey was pressed so that an input event can be sent to userspace. Relevant ACPI code: Method (_L21, 0, NotSerialized) { ... If (AHKF) { Notify (\_SB.FEXT, 0x80) } ... } Method (S000, 3, Serialized) { Name (_T_0, Zero) Local0 = Zero While (One) { _T_0 = Arg0 If (_T_0 == Zero) { Local0 |= 0x04000000 Local0 |= 0x02000000 Local0 |= 0x00020000 Local0 |= 0x0200 Local0 |= 0x0100 Local0 |= 0x20 } ElseIf (_T_0 == One) { ... If (AHKF & 0x08) { Local0 |= 0x04000000 AHKF ^= 0x08 } ... } ... Break } Return (Local0) } Pressing Fn+F4 raises GPE 0x21 and sets bit 3 in AHKF. This in turn results in bit 26 being set in the value returned by FUNC_RFKILL called with 1 as its first argument. On Skylake-based models, bit 26 is also set in the value returned by FUNC_RFKILL called with 0 as its first argument (this value is saved in fujitsu_hotkey->rfkill_supported upon module initialization), which suggests that this bit is set on models which do not handle touchpad toggling transparently to the operating system. Note that bit 3 is cleared in AHKF once FUNC_RFKILL is called with 1 as its first argument, which requires fujitsu-laptop to handle this hotkey in a different manner than the other, GIRB-based hotkeys: two input events (press and release) are immediately sent once Fn+F4 is pressed.

| * | dell-wmi: Generate one sparse keymap for all machinesPali Rohár2016-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks code for generating sparse keymap and processing WMI events. It unifies procedure for generating sparse keymap and also unifies big switch code for processing WMI events of different types. After this patch dell-wmi driver does not differ between "old" and "new" hotkey type. It constructs sparse keymap table with all WMI codes. It is because on some laptops (e.g. Dell Latitude E6440) ACPI/firmware send both event types (old and new). Each WMI code in sparse keymap table is prefixed by 16bit event type, so it does not change functionality on laptops with "old" hotkey support (those without scancodes in DMI). This allow us to distinguish between same WMI codes with different types in sparse keymap. Thanks to this WMI events of type 0x0011 were moved from big switch into sparse keymap table too. This patch also fixes possible bug in parsing WMI event buffer introduced in commit 5ea2559726b7 ("dell-wmi: Add support for new Dell systems"). That commit changed buffer type from int* to u16* without fixing code.

This driver can utilize debugging capabilities and supported features as exposed by the Power Management Controller. Please refer to the below specification for more details on PMC features. http://www.intel.in/content/www/in/en/chipsets/100-series-chipset-datasheet-vol-2.html The current version of this driver exposes SLP_S0_RESIDENCY counter. This counter can be used for detecting fragile SLP_S0 signal related failures and take corrective actions when PCH SLP_S0 signal is not asserted after kernel freeze as part of suspend to idle flow (echo freeze > /sys/power/state). Intel Platform Controller Hub (PCH) asserts SLP_S0 signal when it detects favorable conditions to enter its low power mode. As a pre-requisite the SoC should be in deepest possible Package C-State and devices should be in low power mode. For example, on Skylake SoC the deepest Package C-State is Package C10 or PC10. Suspend to idle flow generally leads to PC10 state but PC10 state may not be sufficient for realizing the platform wide power potential which SLP_S0 signal assertion can provide. SLP_S0 signal is often connected to the Embedded Controller (EC) and the Power Management IC (PMIC) for other platform power management related optimizations. In general, SLP_S0 assertion == PC10 + PCH low power mode + ModPhy Lanes power gated + PLL Idle. As part of this driver, a mechanism to read the SLP_S0_RESIDENCY is exposed as an API and also debugfs features are added to indicate SLP_S0 signal assertion residency in microseconds. echo freeze > /sys/power/state wake the system cat /sys/kernel/debug/pmc_core/slp_s0_residency_usec Signed-off-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@intel.com> Signed-off-by: Vishwanath Somayaji <vishwanath.somayaji@intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>

It should be lit when any radio transmitter is enabled. Its state can be read and set using ACPI (FUNC interface, RFKILL method). Since the Lifebook E734/E744/E754 only has a button (as compared to a slider) for enabling/disabling radio transmitters, I believe the LED in question is meant to indicate whether all radio transmitters are currently on or off. However, pressing the radio toggle button does not automatically change the hardware state of the transmitters: it looks like this machine relies on soft rfkill. As for detecting whether the LED is present on a given machine, I had to resort to educated guesswork. I assumed this LED is present on all devices which have a radio toggle button instead of a slider. My Lifebook E744 holds 0x01010001 in BTNI. By comparing the bits and buttons with those of a Lifebook E8420 (BTNI=0x000F0101, has a slider), I put my money on bit 24 as the indicator of the radio toggle button being present. Furthermore, bit 24 is also clear on the S7020 which does not have the toggle button or an RF LED. Figuring out how the LED is controlled was more deterministic as all it took was decompiling the DSDT and taking a look at method S000 (the RFKILL method of the FUNC interface). The LED control method implemented here is unsuitable for use with "heavy" LED triggers, like phy0rx. Once blinking frequency achieves a certain level, the system hangs.

This means that if the hardware has registers to configure open drain or open source configuration, we use that rather than (as we did before) try to emulate it by switching the line to an input to get high impedance. This is also documented throughly in Documentation/gpio/driver.txt for those of you who did not understand one word of what I just wrote. - Start to do away with the unnecessarily complex and unitelligible ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from the time when the GPIO subsystem was unmaintained. Archs can now just select GPIOLIB and be done with it, cleanups to arches will trickle in for the next kernel. Some minor archs ACKed the changes immediately so these are included in this pull request. - Advancing the use of the data pointer inside the GPIO device for storing driver data by switching the PowerPC, Super-H Unicore and a few other subarches or subsystem drivers in ALSA SoC, Input, serial, SSB, staging etc to use it. - The initialization now reads the input/output state of the GPIO lines, so that each GPIO descriptor knows - if this callback is implemented - whether the line is input or output. This also reflects nicely in userspace "lsgpio". - It is now possible to name GPIO producer names, line names, from the device tree. (Platform data has been supported for a while). I bet we will get a similar mechanism for ACPI one of those days. This makes is possible to get sensible producer names for e.g. GPIO rails in "lsgpio" in userspace. New drivers: - New driver for the Loongson1. - The XLP driver now supports Broadcom Vulcan ARM64. - The IT87 driver now supports IT8620 and IT8628. - The PCA953X driver now supports Galileo Gen2. Driver improvements: - MCP23S08 was switched to use the gpiolib irqchip helpers and now also suppors level-triggered interrupts. - 74x164 and RCAR now supports the .set_multiple() callback - AMDPT was converted to use generic GPIO. - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994 support the new single ended callback for open drain and in some cases open source. - Implement the .get_direction() callback for a few more drivers like PL061, Xgene. Cleanups: - Paul Gortmaker combed through the drivers and de-modularized those who are not really modules. - Move the GPIO poweroff DT bindings to the power subdir where they belong. - Rename gpio-generic.c to gpio-mmio.c, which is much more to the point.
