git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.13 series. Some administrativa: I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO driver coming in through this tree, along with a whole bunch of Exar 8250 fixes. These are ACKed by Greg and also hit drivers/platform/* where they are ACKed by Andy Shevchenko. Speaking about drivers/platform/* there is also a bunch of ACPI stuff coming through that route, again ACKed by Andy. The MCP23S08 changes are coming in here as well. You already have the commits in your tree, so this is just a result of sharing an immutable branch between pin control and GPIO. Core: - Export add/remove for lookup tables so that modules can export GPIO descriptor tables. - Handle GPIO sleep states: it is now possible to flag that a GPIO line may loose its state during suspend/resume of the system to save power. This is used in the Wolfson Micro Arizona driver. - ACPI-based GPIO was tightened up a lot around the edges. - Use bitmap_fill() to speed up a loop. New drivers: - Exar XRA1403 SPI-based GPIO. - MVEBU driver now supports Armada 7K and 8K. - LP87565 PMIC GPIO. - Renesas R-CAR R8A7743 (RZ/G1M). - The new IOT2040 8250 serial/GPIO also comes in through this changeset. Substantial driver changes: - Seriously fix the Exar 8250 GPIO portions to work. - The MCP23S08 was moved out to a pin control driver. - Convert MEVEBU to use regmap for register access. - Drop Vulcan support from the Broadcom driver. - Serious cleanup and improvement of the mockup driver, giving us a better test coverage. Misc: - Lots of janitorial clean up. - A bunch of documentation fixes" * tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (70 commits) serial: exar: Add support for IOT2040 device gpio-exar/8250-exar: Make set of exported GPIOs configurable platform: Accept const properties serial: exar: Factor out platform hooks gpio-exar/8250-exar: Rearrange gpiochip parenthood gpio: exar: Fix iomap request gpio-exar/8250-exar: Do not even instantiate a GPIO device for Commtech cards serial: uapi: Add support for bus termination gpio: rcar: Add R8A7743 (RZ/G1M) support gpio: gpio-wcove: Fix GPIO control register offset calculation gpio: lp87565: Add support for GPIO gpio: dwapb: fix missing first irq for edgeboth irq type MAINTAINERS: Take maintainership for GPIO ACPI support gpio: exar: Fix reading of directions and values gpio: exar: Allocate resources on behalf of the platform device gpio-exar/8250-exar: Fix passing in of parent PCI device gpio: mockup: use devm_kcalloc() where applicable gpio: mockup: add myself as author gpio: mockup: improve the error message gpio: mockup: don't return magic numbers from probe() ...

2017-06-23Input: synaptics-rmi4 - only read the F54 query registers which are usedAndrew Duggan1-10/+7
The F54 driver is currently only using the first 6 bytes of F54 so there is no need to read all 27 bytes. Some Dell systems (Dell XP13 9333 and similar) have an issue with the touchpad or I2C bus when reading reports larger then 16 bytes. Reads larger then 16 bytes are reported in two HID reports. Something about the back to back reports seems to cause the next read to report incorrect data. This results in F30 failing to load and the click button failing to work. Previous issues with the I2C controller or touchpad were addressed in: commit 5b65c2a02966 ("HID: rmi: check sanity of the incoming report") Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=195949 Signed-off-by: Andrew Duggan <[email protected]> Reviewed-by: Benjamin Tissoires <[email protected]> Reviewed-by: Nick Dyer <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2017-06-18Input: xpad - sync supported devices with XBCDBenjamin Valentin1-0/+30
XBCD [0][1] is an OpenSource driver for Xbox controllers on Windows. Later it also started supporting Xbox360 controllers (presumably before the official Windows driver was released). It contains a couple device IDs unknown to the Linux driver, so I extracted those from xbcd.inf and added them to our list. It has a special type for Wheels and I have the feeling they might need some extra handling. They all have 'Wheel' in their name, so that information is available for future improvements.

2017-06-18Input: xpad - sync supported devices with 360ControllerBenjamin Valentin1-0/+57
360Controller [0] is an OpenSource driver for Xbox/Xbox360/XboxOne controllers on macOS. It contains a couple device IDs unknown to the Linux driver, so I wrote a small Python script [1] to extract them and feed them into my previous script [2] to compare them with the IDs known to Linux. For most devices, this information is not really needed as xpad is able to automatically detect the type of an unknown Xbox Controller at run-time. I've therefore stripped all the generic/vague entries. I've excluded the Logitech G920, it's handled by a HID driver already. I've also excluded the Scene It! Big Button IR, it's handled by an out-of-tree driver.

2017-06-09Input: synaptics-rmi4 - register F03 port as pass-through serioDmitry Torokhov1-1/+1
The 5th generation Thinkpad X1 Carbons use Synaptics touchpads accessible over SMBus/RMI, combined with ALPS or Elantech trackpoint devices instead of classic IBM/Lenovo trackpoints. Unfortunately there is no way for ALPS driver to detect whether it is dealing with touchpad + trackpoint combination or just a trackpoint, so we end up with a "phantom" dualpoint ALPS device in addition to real touchpad and trackpoint. Given that we do not have any special advanced handling for ALPS or Elantech trackpoints (unlike IBM trackpoints that have separate driver and a host of options) we are better off keeping the trackpoints in PS/2 emulation mode. We achieve that by setting serio type to SERIO_PS_PSTHRU, which will limit number of protocols psmouse driver will try. In addition to getting rid of the "phantom" touchpads, this will also speed up probing of F03 pass-through port.
