2017-06-05Input: add support for the STMicroelectronics FingerTip touchscreenAndi Shyti3-0/+834
The stmfts (ST-Microelectronics FingerTip S) touchscreen device is a capacitive multi-touch controller mainly for mobile use. It's connected through i2c bus at the address 0x49 and it interfaces with userspace through input event interface. At the current state it provides a touchscreen multitouch functionality up to 10 fingers. Each finger is enumerated with a distinctive id (from 0 to 9). If enabled the device can support single "touch" hovering, by providing three coordinates, x, y and distance. It is possible to select the touchkey functionality which provides a basic two keys interface for "home" and "back" menu, typical in mobile phones.

2017-06-02Input: axp20x-pek - switch to acpi_dev_present and check for ACPI0011 tooHans de Goede1-2/+3
acpi_dev_found checks that there is a matching ACPI node, but it may be disabled (_STA method returns 0) in which case the soc_button_array driver will not bind to it and axp20x-pek should handle the power-button. This commit switches from acpi_dev_found to acpi_dev_present to avoid not registering an input-dev for the powerbutton when there is a disabled PNP0C40 device. The ACPI-6.0 standard defines a standard gpio button device using the ACPI0011 HID replacing the custom PNP0C40 gpio device, many newer devices define both PNP0C40 and ACPI0011 devices enabling one or the other depending on whether the BIOS thinks it is going to boot Android or Windows. This commit adds a check for the ACPI0011 device, so that if either device is present *and* enabled we don't register an input-dev for the powerbutton.

2017-06-02Input: axp20x-pek - only check for "INTCFD9" ACPI device on Cherry TrailHans de Goede1-7/+36
Commit 9b13a4ca8d2c ("Input: axp20x-pek - do not register input device on some systems") added a check for the INTCFD9 ACPI device which also handles the powerbutton as on some systems the powerbutton is connected to both the PMIC, handled by axp20x-pek, and to a gpio on the SoC, handled by soc_button_array which attaches itself to the INTCFD9 ACPI device. Testing + comparing DSDTs has shown that this only happens on Cherry Trail devices with an AXP288 PMIC, the AXP288 PMIC is also used on Bay Trail devices but there the power button is only connected to the PMIC and not handled by soc_button_array. This means that the INTCFD9 check has caused a regression on Bay Trail devices, causing power-button presses to no longer be seen. This commit fixes this by limiting the check to devices where the ACPI node for the AXP288 contains a _HRV (hardware revision) attribute with a value of 3 which indicates we are dealing with a Cherry Trail platform.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull hw lockdown support from David Howells: "Annotation of module parameters that configure hardware resources including ioports, iomem addresses, irq lines and dma channels. This allows a future patch to prohibit the use of such module parameters to prevent that hardware from being abused to gain access to the running kernel image as part of locking the kernel down under UEFI secure boot conditions. Annotations are made by changing: module_param(n, t, p) module_param_named(n, v, t, p) module_param_array(n, t, m, p) to: module_param_hw(n, t, hwtype, p) module_param_hw_named(n, v, t, hwtype, p) module_param_hw_array(n, t, hwtype, m, p) where the module parameter refers to a hardware setting hwtype specifies the type of the resource being configured. This can be one of: ioport Module parameter configures an I/O port iomem Module parameter configures an I/O mem address ioport_or_iomem Module parameter could be either (runtime set) irq Module parameter configures an I/O port dma Module parameter configures a DMA channel dma_addr Module parameter configures a DMA buffer address other Module parameter configures some other value Note that the hwtype is compile checked, but not currently stored (the lockdown code probably won't require it). It is, however, there for future use. A bonus is that the hwtype can also be used for grepping. The intention is for the kernel to ignore or reject attempts to set annotated module parameters if lockdown is enabled. This applies to options passed on the boot command line, passed to insmod/modprobe or direct twiddling in /sys/module/ parameter files. The module initialisation then needs to handle the parameter not being set, by (1) giving an error, (2) probing for a value or (3) using a reasonable default. What I can't do is just reject a module out of hand because it may take a hardware setting in the module parameters. Some important modules, some ipmi stuff for instance, both probe for hardware and allow hardware to be manually specified; if the driver is aborts with any error, you don't get any ipmi hardware. Further, trying to do this entirely in the module initialisation code doesn't protect against sysfs twiddling. [!] Note that in and of itself, this series of patches should have no effect on the the size of the kernel or code execution - that is left to a patch in the next series to effect.

New drivers: - A new single-register fixed-direction framework driver for hardware that have lines controlled by a single register that just work in one direction (out or in), including IRQ support. - Support the Fintek F71889A GPIO SuperIO controller. - Support the National NI 169445 MMIO GPIO. - Support for the X-Gene derivative of the DWC GPIO controller - Support for the Rohm BD9571MWV-M PMIC GPIO controller. - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver and replace both the Gemini and the Moxa ART custom drivers with this driver. Driver improvements: - A whole slew of drivers have their spinlocks chaned to raw spinlocks as they provide irqchips, and thus we are progressing on realtime compliance. - Use devm_irq_alloc_descs() in a slew of drivers, getting managed resources. - Support for the embedded PWM controller inside the MVEBU driver. - Debounce, open source and open drain support for the Aspeed driver. - Misc smaller fixes like spelling and syntax and whatnot" * tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: f7188x: Add a missing break gpio: omap: return error if requested debounce time is not possible gpio: Add ROHM BD9571MWV-M PMIC GPIO driver gpio: gpio-wcove: fix GPIO IRQ status mask gpio: DT bindings, move tca9554 from pcf857x to pca953x gpio: move tca9554 from pcf857x to pca953x gpio: arizona: Correct check whether the pin is an input gpio: Add XRA1403 DTS binding documentation dt-bindings: add exar to vendor prefixes list gpio: gpio-wcove: fix irq pending status bit width gpio: dwapb: use dwapb_read instead of readl_relaxed gpio: aspeed: Add open-source and open-drain support gpio: aspeed: Add debounce support gpio: aspeed: dt: Add optional clocks property gpio: aspeed: dt: Fix description alignment in bindings document gpio: mvebu: Add limited PWM support gpio: Use unsigned int for interrupt numbers gpio: f7188x: Add F71889A GPIO support. gpio: core: Decouple open drain/source flag with active low/high gpio: arizona: Correct handling for reading input GPIOs ...
