On Qualcomm Technologies, Inc. PMIC PMK8350, the PON peripheral is split into two peripherals: PON_HLOS and PON_PBS. The application processor only has write access to PON_HLOS which limits it to only receiving PON interrupts. Add support for the PMK8350 PON_HLOS peripheral so that its KPDPWR_N and RESIN_N interrupts can be used to detect key presses.

2020-12-09Input: add driver for power button on Dell Wyse 3020Lubomir Rintel
This adds support for the power button attached to the Embedded Controller on a Dell Wyse 3020 "Ariel" board. The Embedded Controller's SPI interface is actually capable sending and receiving the PS/2 keyboard and mouse protocol data, which looks like a good fit for a serio driver. Howerver, I don't know of any machines where this is actually used. My board only has a single power button and no way to connect an actual keyboard or a mouse. Using the atkbd driver with serio would be an overkill and would be inconvenient for the userspace. Therefore this driver registers an input device that is only capable of reporting the power button presses and releases.

2020-09-13Input: soc_button_array - work around DSDTs which modify the irqflagsHans de Goede
Some 2-in-1s which use the soc_button_array driver have this ugly issue in their DSDT where the _LID method modifies the irq-type settings of the GPIOs used for the power and home buttons. The intend of this AML code is to disable these buttons when the lid is closed. The AML does this by directly poking the GPIO controllers registers. This is problematic because when re-enabling the irq, which happens whenever _LID gets called with the lid open (e.g. on boot and on resume), it sets the irq-type to IRQ_TYPE_LEVEL_LOW. Where as the gpio-keys driver programs the type to, and expects it to be, IRQ_TYPE_EDGE_BOTH. This commit adds a workaround for this which (on affected devices) does not set gpio_keys_button.gpio on these 2-in-1s, instead it gets the irq for the GPIO, configures it as IRQ_TYPE_LEVEL_LOW (to match how the _LID AML code configures it) and passes the irq in gpio_keys_button.irq.

2020-09-13Input: soc_button_array - add support for INT33D3 tablet-mode switch devicesHans de Goede
According to the Microsoft documentation for Windows 8 convertible devices, these devices should implement a PNP0C60 "laptop/slate mode state indicator" ACPI device. This device can work in 2 ways, if there is a GPIO which directly indicates the device is in tablet-mode or not then the direct-gpio mode should be used. If there is no such GPIO, but instead the events are coming from e.g. the embedded-controller, then there should still be a PNP0C60 ACPI device and event-injection should be used to send the events. The drivers/platform/x86/intel-vbtn.c code is an example from a standardized manner of doing the latter. On various 2-in-1s with either a detachable keyboard, or with 360° hinges, the direct GPIO mode is indicated by an ACPI device with a HID of INT33D3, which contains a single GpioInt in its ACPI resource table, which directly indicates if the device is in tablet-mode or not. This commit adds support for this to the soc_button_array code, as well as for the alternative ID9001 HID which some devices use instead of the INT33D3 HID.

2020-09-13Input: soc_button_array - add active_low setting to soc_button_infoHans de Goede
This is a preparation patch for adding support for Intel INT33D3 ACPI devices. These INT33D3 devices follow yet another Intel defined (but not documented) ACPI GPIO button standard. Unlike the ACPI GPIO button devices supported so far, the GPIO used in the INT33D3 devices is active-high, rather then active-low. This commit makes setting the gpio_keys_button.active_low flag configurable through the soc_button_info struct and enables it for all currently supported devices.

2020-08-06Input: ims-pcu - return error code rather than -ENOMEMColin Ian King
Currently the assignment of -ENOMEM to error is redundant because error is not being read and -ENOMEM is being hard coded as an error return. Fix this by returning the error code in variable 'error'; this also allows the error code from a failed call to input_register_device to be preserved and returned to the caller rather than just returning a possibly inappropriate -ENOMEM.

2020-05-05Input: axp20x-pek - always register interrupt handlersHans de Goede
On some X86 devices we do not register an input-device, because the power-button is also handled by the soc_button_array (GPIO) input driver, and we want to avoid reporting power-button presses to userspace twice. Sofar when we did this we also did not register our interrupt handlers, since those were only necessary to report input events. But on at least 2 device models the Medion Akoya E1239T and the GPD win, the GPIO pin used by the soc_button_array driver for the power-button cannot wakeup the system from suspend. Why this does not work is not clear, I've tried comparing the value of all relevant registers on the Cherry Trail SoC, with those from models where this does work. I've checked: PMC registers: FUNC_DIS, FUNC_DIS2, SOIX_WAKE_EN, D3_STS_0, D3_STS_1, D3_STDBY_STS_0, D3_STDBY_STS_1; PMC ACPI I/O regs: PM1_STS_EN, GPE0a_EN and they all have identical contents in the working and non working cases. I suspect that the firmware either sets some unknown register to a value causing this, or that it turns off a power-plane which is necessary for GPIO wakeups to work during suspend. What does work on the Medion Akoya E1239T is letting the AXP288 wakeup the system on a power-button press (the GPD win has a different PMIC). Move the registering of the power-button press/release interrupt-handler from axp20x_pek_probe_input_device() to axp20x_pek_probe() so that the PMIC will wakeup the system on a power-button press, even if we do not register an input device.

2020-01-21Input: axp20x-pek - respect userspace wakeup configurationSamuel Holland
Unlike most other power button drivers, this driver unconditionally enables its wakeup IRQ. It should be using device_may_wakeup() to respect the userspace configuration of wakeup sources. Because the AXP20x MFD device uses regmap-irq, the AXP20x PEK IRQs are nested off of regmap-irq's threaded interrupt handler. The device core ignores such interrupts, so to actually disable wakeup, we must explicitly disable all non-wakeup interrupts during suspend.

2020-01-20Input: pm8xxx-vib - fix handling of separate enable registerStephan Gerhold
Setting the vibrator enable_mask is not implemented correctly: For regmap_update_bits(map, reg, mask, val) we give in either regs->enable_mask or 0 (= no-op) as mask and "val" as value. But "val" actually refers to the vibrator voltage control register, which has nothing to do with the enable_mask. So we usually end up doing nothing when we really wanted to enable the vibrator. We want to set or clear the enable_mask (to enable/disable the vibrator). Therefore, change the call to always modify the enable_mask and set the bits only if we want to enable the vibrator.
