The RMI4 header doc says that this property is there to force the buttonpad property, so we also need to detect it by looking at the exported buttons count.

Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.

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. Add support for multiple instances. - .set_multiple() and naming of lines on more or less all of the ISA/PCI GPIO controllers. - mcp23s08: refactored to use regmap as a first step to further rewrites and modernizations" * tag 'gpio-v4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (61 commits) gpio: reintroduce devm_get_gpiod_from_child() gpio: pci-idio-16: Fix PCI BAR index gpio: pci-idio-16: Fix PCI device ID code gpio: mockup: implement event injecting over debugfs gpio: mockup: add a dummy irqchip gpio: mockup: implement naming the lines gpio: mockup: code shrink gpio: mockup: readability tweaks gpio: Add GPIO support for the ACCES PCI-IDIO-16 gpio: Add the devm_fwnode_get_index_gpiod_from_child() helper gpio: Rename devm_get_gpiod_from_child() gpio: mcp23s08: Select REGMAP/REGMAP_I2C to fix build error gpio: ws16c48: Add support for GPIO names gpio: gpio-mm: Add support for GPIO names gpio: 104-idio-16: Add support for GPIO names gpio: 104-idi-48: Add support for GPIO names gpio: 104-dio-48e: Add support for GPIO names gpio: ws16c48: Remove unnecessary driver_data set gpio: gpio-mm: Remove unnecessary driver_data set gpio: 104-idio-16: Remove unnecessary driver_data set ... 2017-02-20T23:16:02+00:00 Dmitry Torokhov dmitry.torokhov@gmail.com 2017-02-20T23:16:02+00:00 urn:sha1:6e11617fcff3688f70650a3e40addb0043dda137 Prepare input updates for 4.11 merge window. 2017-02-20T23:12:26+00:00 Javier Martinez Canillas javier@osg.samsung.com 2017-02-20T23:06:39+00:00 urn:sha1:a1b5359271e5c77d5ec8a575b379a6ba3e867097 The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

This will still allow legacy boards to use the driver (by defining property sets and attaching them to the drivers) and will simplify probe and make driver usable on ACPI-based systems as well.

Also, the regulator is not optional, it may simply be missing from platform description, so let's use devm_regulator_get() and rely on regulator core to give us dummy supply when real one is not available.
