Merge tag 'gpio-v4.17-1' of 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 v4.17 kernel cycle: New drivers: - Nintendo Wii GameCube GPIO, known as "Hollywood" - Raspberry Pi mailbox service GPIO expander - Spreadtrum main SC9860 SoC and IEC GPIO controllers. Improvements: - Implemented .get_multiple() callback for most of the high-performance industrial GPIO cards for the ISA bus. - ISA GPIO drivers now select the ISA_BUS_API instead of depending on it. This is merged with the same pattern for all the ISA drivers and some other Kconfig cleanups related to this. Cleanup: - Delete the TZ1090 GPIO drivers following the deletion of this SoC from the ARM tree. - Move the documentation over to driver-api to conform with the rest of the kernel documentation build. - Continue to make the GPIO drivers include only <linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we want to get rid of. - Managed to remove VLA allocation from two drivers pending more fixes in this area for the next merge window. - Misc janitorial fixes" * tag 'gpio-v4.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: Add Spreadtrum PMIC EIC driver support gpio: Add Spreadtrum EIC driver support dt-bindings: gpio: Add Spreadtrum EIC controller documentation gpio: ath79: Fix potential NULL dereference in ath79_gpio_probe() pinctrl: qcom: Don't allow protected pins to be requested gpiolib: Support 'gpio-reserved-ranges' property gpiolib: Change bitmap allocation to kmalloc_array gpiolib: Extract mask allocation into subroutine dt-bindings: gpio: Add a gpio-reserved-ranges property gpio: mockup: fix a potential crash when creating debugfs entries gpio: pca953x: add compatibility for pcal6524 and pcal9555a gpio: dwapb: Add support for a bus clock gpio: Remove VLA from xra1403 driver gpio: Remove VLA from MAX3191X driver gpio: ws16c48: Implement get_multiple callback gpio: gpio-mm: Implement get_multiple callback gpio: 104-idi-48: Implement get_multiple callback gpio: 104-dio-48e: Implement get_multiple callback gpio: pcie-idio-24: Implement get_multiple/set_multiple callbacks gpio: pci-idio-16: Implement get_multiple callback ...

-ImgTec TZ1090 GPIO Controller
-
-Required properties:
-- compatible: Compatible property value should be "img,tz1090-gpio".
-
-- reg: Physical base address of the controller and length of memory mapped
- region.
-
-- #address-cells: Should be 1 (for bank subnodes)
-
-- #size-cells: Should be 0 (for bank subnodes)
-
-- Each bank of GPIOs should have a subnode to represent it.
-
- Bank subnode required properties:
- - reg: Index of bank in the range 0 to 2.
-
- - gpio-controller: Specifies that the node is a gpio controller.
-
- - #gpio-cells: Should be 2. The syntax of the gpio specifier used by client
- nodes should have the following values.
- <[phandle of the gpio controller node]
- [gpio number within the gpio bank]
- [gpio flags]>
-
- Values for gpio specifier:
- - GPIO number: a value in the range 0 to 29.
- - GPIO flags: bit field of flags, as defined in <dt-bindings/gpio/gpio.h>.
- Only the following flags are supported:
- GPIO_ACTIVE_HIGH
- GPIO_ACTIVE_LOW
-
- Bank subnode optional properties:
- - gpio-ranges: Mapping to pin controller pins (as described in
- Documentation/devicetree/bindings/gpio/gpio.txt)
-
- - interrupts: Interrupt for the entire bank
-
- - interrupt-controller: Specifies that the node is an interrupt controller
-
- - #interrupt-cells: Should be 2. The syntax of the interrupt specifier used by
- client nodes should have the following values.
- <[phandle of the interurupt controller]
- [gpio number within the gpio bank]
- [irq flags]>
-
- Values for irq specifier:
- - GPIO number: a value in the range 0 to 29
- - IRQ flags: value to describe edge and level triggering, as defined in
- <dt-bindings/interrupt-controller/irq.h>. Only the following flags are
- supported:
- IRQ_TYPE_EDGE_RISING
- IRQ_TYPE_EDGE_FALLING
- IRQ_TYPE_EDGE_BOTH
- IRQ_TYPE_LEVEL_HIGH
- IRQ_TYPE_LEVEL_LOW
-

-Example:
-
- gpios: gpio-controller@2005800 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "img,tz1090-gpio";
- reg = <0x02005800 0x90>;
-
- /* bank 0 with an interrupt */
- gpios0: bank@0 {
- #gpio-cells = <2>;
- #interrupt-cells = <2>;
- reg = <0>;
- interrupts = <13 IRQ_TYPE_LEVEL_HIGH>;
- gpio-controller;
- gpio-ranges = <&pinctrl 0 0 30>;
- interrupt-controller;
- };
-
- /* bank 2 without interrupt */
- gpios2: bank@2 {
- #gpio-cells = <2>;
- reg = <2>;
- gpio-controller;
- gpio-ranges = <&pinctrl 0 60 30>;
