Merge tag 'gpio-v4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Luinus Walleij: "Bulk GPIO changes for the v4.10 kernel cycle: Core changes: - Simplify threaded interrupt handling: instead of passing numbed parameters to gpiochip_irqchip_add_chained() we create a new call: gpiochip_irqchip_add_nested() so the two types are clearly semantically different. Also make sure that all nested chips call gpiochip_set_nested_irqchip() which is necessary for IRQ resend to work properly if it happens. - Return error on seek operations for the chardev. - Clamp values set as part of gpio[d]_direction_output() so that anything != 0 will be send down to the driver as "1" not the value passed in. - ACPI can now support naming of GPIO lines, hogs and holes in the GPIO lists. New drivers: - The SX150x driver was deemed unfit for the GPIO subsystem and was moved over to a combined GPIO+pinctrl driver in the pinctrl subsystem. New features: - Various cleanups to various drivers" * tag 'gpio-v4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (49 commits) gpio: merrifield: Implement gpio_get_direction callback gpio: merrifield: Add support for hardware debouncer gpio: chardev: Return error for seek operations gpio: arizona: Tidy up probe error path gpio: arizona: Remove pointless set of platform drvdata gpio: pl061: delete platform data handling gpio: pl061: move platform data into driver gpio: pl061: rename variable from chip to pl061 gpio: pl061: rename state container struct gpio: pl061: use local state for parent IRQ storage gpio: set explicit nesting on drivers gpio: simplify adding threaded interrupts gpio: vf610: use builtin_platform_driver gpio: axp209: use correct register for GPIO input status gpio: stmpe: fix interrupt handling bug gpio: em: depnd on ARCH_SHMOBILE gpio: zx: depend on ARCH_ZX gpio: x86: update config dependencies for x86 specific hardware gpio: mb86s7x: use builtin_platform_driver gpio: etraxfs: use builtin_platform_driver ...

ACPI / property: Document usage rules for _DSD properties

2016-12-06T01:13:28+00:00

Following some discussions during the Kernel Summit and LPC, document what can be returned from ACPI _DSD as device properties and when it is valid to use the special PRP0001 device ID. Signed-off-by: Rafael J. Wysocki Reviewed-by: Mika Westerberg Acked-by: Andy Shevchenko Reviwed-by: Mark Brown

ACPI: Document _OSI and _REV for Linux BIOS writers

2016-12-03T01:36:26+00:00

Based on a recent session at the Linux Plumber's Conference, we need to be more clear about how a BIOS should use _OSI to properly support Linux. Signed-off-by: Len Brown Reviewed-by: Lukas Wunner Signed-off-by: Rafael J. Wysocki

ACPI / gpio: Add support for naming GPIOs

2016-10-24T14:33:11+00:00

Now that we have the new helper function that sets nice names for GPIO lines based on "gpio-line-names" device property, we can take advantage of this in acpi_gpiochip_add(). Signed-off-by: Mika Westerberg Signed-off-by: Linus Walleij

ACPI / gpio: Add hogging support

2016-10-24T14:33:11+00:00

GPIO hogging means that the GPIO controller can "hog" and configure certain GPIOs without need for a driver or userspace to do that. This is useful in open-connected boards where BIOS cannot possibly know beforehand which devices will be connected to the board. This adds GPIO hogging mechanism to ACPI analogous to Device Tree.

ACPI / gpio: Allow holes in list of GPIOs for a device

2016-10-24T14:33:11+00:00

Make it possible to have an empty GPIOs in a GPIO list for device. For example a SPI master may use both GPIOs and native pins as chip selects and we need to be able to distinguish between the two. This makes it mandatory to have exactly 3 arguments for GPIOs and then converts gpiolib to use of __acpi_node_get_property_reference() instead. In addition we make acpi_gpio_package_count() to handle holes as well (this matches the DT version). Signed-off-by: Mika Westerberg Acked-by: Rafael J. Wysocki Signed-off-by: Linus Walleij
