Pull gpio updates from Bartosz Golaszewski:
 "We have a lot of code refactoring using common helpers and ended up
  removing more lines then we're adding this release cycle.

  Nothing really stands out, just small updates all over the place.

  Core GPIOLIB updates:
   - wake-up poll() in user-space on device unbind
   - improve fwnode usage
   - interrupt domain handling improvements
   - correctly handle the ngpios property in gpio-mmio

  Driver cleanups:
   - remove unneeded calls to platform_set_drvdata() all around the
     place
   - remove unneeded of_match_ptr() expansions whenever a driver depends
     on CONFIG_OF
   - remove redundant calls to dev_err_probe() from gpio-omap and
     gpio-davinci

  Driver improvements:
   - use autopointers and guards from cleanup.h in gpio-sim
   - shrink code in gpio-sim using some common helpers
   - convert the idio family of drivers to using gpio-regmap
   - convert gpio-ws16c48 to using gpio-regmap
   - use devres to simplify code in gpio-pisosr and gpio-mxc
   - update gpio-sifive: support IRQ wake, improve interrupt handling,
     allow building as module
   - make gpio-ge and gpio-bcm-kona OF-independent (plus some minor
     tweaks)
   - add support for new models in gpio-pca953x and gpio-ds4520
   - add runtime PM support to gpio-mxc
   - fix a build warning in gpio-mxs
   - add support for adding pin ranges to gpio-mlxbf3
   - add counter/timer support to gpio-104-dio-48e
   - switch to dynamic GPIO base allocation in gpio-vf610
   - minor oneliners here and there

  Device-tree bindings updates:
   - enable the gpio-line-names property in snps,dw-apb and STMPE GPIO
   - document new models in fsl-imx-gpio, ds4520 and pca95xx
   - convert the bindings for brcm,kona-gpio to YAML"

-Broadcom Kona Family GPIO
-=========================
-
-This GPIO driver is used in the following Broadcom SoCs:
-  BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
-
-The Broadcom GPIO Controller IP can be configured prior to synthesis to
-support up to 8 banks of 32 GPIOs where each bank has its own IRQ. The
-GPIO controller only supports edge, not level, triggering of interrupts.
-
-Required properties
--------------------
-
-- compatible: "brcm,bcm11351-gpio", "brcm,kona-gpio"
-- reg: Physical base address and length of the controller's registers.
-- interrupts: The interrupt outputs from the controller. There is one GPIO
-  interrupt per GPIO bank. The number of interrupts listed depends on the
-  number of GPIO banks on the SoC. The interrupts must be ordered by bank,
-  starting with bank 0. There is always a 1:1 mapping between banks and
-  IRQs.
-- #gpio-cells: Should be <2>. The first cell is the pin number, the second
-  cell is used to specify optional parameters:
-  - bit 0 specifies polarity (0 for normal, 1 for inverted)
-  See also "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
-- #interrupt-cells: Should be <2>. The first cell is the GPIO number. The
-  second cell is used to specify flags. The following subset of flags is
-  supported:
-  - trigger type (bits[1:0]):
-      1 = low-to-high edge triggered.
-      2 = high-to-low edge triggered.
-      3 = low-to-high or high-to-low edge triggered
-      Valid values are 1, 2, 3
-  See also .../devicetree/bindings/interrupt-controller/interrupts.txt.
-- gpio-controller: Marks the device node as a GPIO controller.
-- interrupt-controller: Marks the device node as an interrupt controller.

-Example:
-	gpio: gpio@35003000 {
-		compatible = "brcm,bcm11351-gpio", "brcm,kona-gpio";
-		reg = <0x35003000 0x800>;
-		interrupts =
-		       <GIC_SPI 106 IRQ_TYPE_LEVEL_HIGH
-			GIC_SPI 115 IRQ_TYPE_LEVEL_HIGH
-			GIC_SPI 114 IRQ_TYPE_LEVEL_HIGH
-			GIC_SPI 113 IRQ_TYPE_LEVEL_HIGH
-			GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH
-			GIC_SPI 111 IRQ_TYPE_LEVEL_HIGH>;
-		#gpio-cells = <2>;
-		#interrupt-cells = <2>;
-		gpio-controller;
-		interrupt-controller;
