Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.11 cycle Core changes: - Augment fwnode_get_named_gpiod() to configure the GPIO pin immediately after requesting it like all other APIs do. This is a treewide change also updating all users. - Pass a GPIO label down to gpiod_request() from fwnode_get_named_gpiod(). This makes debugfs and the userspace ABI correctly reflect the current in-kernel consumer of a pin taken using this abstraction. This is a treewide change also updating all users. - Rename devm_get_gpiod_from_child() to devm_fwnode_get_gpiod_from_child() to reflect the fact that this function is operating on a fwnode object. This is a treewide change also updating all users. - Make it possible to take multiple GPIOs in a single hog of device tree hogs. - The refactorings switching GPIO chips to use the .set_config() callback using standard pin control properties and providing a backend into the pin control subsystem that were also merged into the pin control tree naturally appear here too. Testing instrumentation: - A whole slew of cleanups and improvements to the mockup GPIO driver. We now have an extended userspace test exercising the subsystem, and we can inject interrupts etc from userspace to fully test the core GPIO functionality. New drivers: - New driver for the Cortina Systems Gemini GPIO controller. - New driver for the Exar XR17V352/354/358 chips. - New driver for the ACCES PCI-IDIO-16 PCI GPIO card. Driver changes: - RCAR: set the irqchip parent device, add fine-grained runtime PM support. - pca953x: support optional RESET control line on the chip. - DaVinci: cleanups and simplifications.

Instead of supporting legacy platform data (of which we have no mainline users) and OF-based properties, let's switch to generic device properties.

2017-02-09Input: joydev - do not report stale values on first openRaphael Assenat1-5/+13
Postpone axis initialization to the first open instead of doing it in joydev_connect. This is to make sure the generated startup events are representative of the current joystick state rather than what it was when joydev_connect() was called, potentially much earlier. Once the first user is connected to joydev node we'll be updating joydev->abs[] values and subsequent clients will be getting correct initial states as well. This solves issues with joystick driven menus that start scrolling up each time they are started, until the user moves the joystick to generate events. In emulator menu setups where the menu program is restarted every time the game exits, the repeated need to move the joystick to stop the unintended scrolling gets old rather quickly...

The tracksticks on the Lenovo thinkpads have their buttons connected through the touchpad device. We already fixed that in synaptics.c, but when we switch the device into RMI4 mode to have proper support, the pass-through functionality can't deal with them easily. We add a new PS/2 flag and protocol designed for psmouse. The RMI4 F03 pass-through can then emit a special set of commands to notify psmouse the state of the buttons. This patch implements the protocol in psmouse, while an other will do the same for rmi4-f03.

These attributes provide various bits of information which may be enumerated under the RMI4 protocol to user space. This may be useful for displaying the particular version which is in use, or selecting the correct firmware to flash.

2017-01-31Input: mousedev - stop offering PS/2 to userspace by defaultDmitry Torokhov1-3/+0
Evdev interface has been available for many years and by now everyone is switched to using it, so let's stop offering /dev/input/mouseN and /dev/psaux by default.

2017-01-31Input: tca8418 - switch to using generic device propertiesDmitry Torokhov1-64/+26
Let's drop legacy platform data support (there are no users in mainline) and switch to using generic device properties, which will make the driver simpler (non-OF boards can use property sets to describe hardware).

2017-01-31Input: matrix-keypad - switch to using generic device propertiesDmitry Torokhov11-66/+70
Instead of being OF-specific, let's switch to using generic device properties, which will make this code usable on ACPI, device tree and legacy boards that use property sets. As part of the change let's rename matrix_keypad_parse_of_params() to matrix_keypad_parse_properties(). Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
