Pull pin control updates from Linus Walleij:
 "The most interesting aspect is that we now have initial support for
  the Apple pin controller as used in the M1 laptops and the iPhones
  which is a step forward for using Linux efficiently on this Apple
  silicon.

  Core changes:

   - Add infrastructure for per-parent interrupt data to support the
     Apple pin controller.

  New drivers:

   - New combined pin control and GPIO driver for the Apple SoC. This is
     used in all modern Apple silicon such as the M1 laptops but also in
     at least recent iPhone variants.

   - New subdriver for the Qualcomm SM6350

   - New subdriver for the Qualcomm QCM2290

   - New subdriver for the Qualcomm PM6350

   - New subdriver for the Uniphier NX1

   - New subdriver for the Samsung ExynosAutoV9

   - New subdriver for the Mediatek MT7986

   - New subdriver for the nVidia Tegra194

  Improvements:

   - Improve power management in the Mediatek driver.

   - Improvements to the Renesas internal consistency checker.

   - Convert the Rockchip pin control device tree bindings to YAML.

   - Finally convert the Qualcomm PMIC SSBI and SPMI MPP GPIO driver to
     use hierarchical interrupts.

   - Convert the Qualcomm PMIC MPP device tree bindings to YAML"

-		    if the device is on an spmi bus or an ssbi bus respectively.
-
-- reg:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: Register base of the MPP block and length.
-
-- interrupts:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: Must contain an array of encoded interrupt specifiers for
-		    each available MPP
-

-
-- #gpio-cells:
-	Usage: required
-	Value type: <u32>
-	Definition: Must be 2;
-		    the first cell will be used to define MPP number and the
-		    second denotes the flags for this MPP
-
-Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-a general description of GPIO and interrupt bindings.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin or a list of pins. This configuration can include the
-mux function to select on those pin(s), and various pin configuration
-parameters, as listed below.
-
-SUBNODES:
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
-
-- pins:
-	Usage: required
-	Value type: <string-array>
-	Definition: List of MPP pins affected by the properties specified in
-		    this subnode.  Valid pins are:

-		    mpp1-mpp4 for pmi8950
-		    mpp1-mpp4 for pma8084
-
-- function:
-	Usage: required
-	Value type: <string>
-	Definition: Specify the alternative function to be configured for the
-		    specified pins.  Valid values are:
-		    "digital",
-		    "analog",
-		    "sink"
-
-- bias-disable:

-	Value type: <none>
-	Definition: The specified pins should be configured as no pull.
-

-		    Valid values are 600, 10000 and 30000 in bidirectional mode
-		    only, i.e. when operating in qcom,analog-mode and input and
-		    outputs are enabled. The hardware ignores the configuration
-		    when operating in other modes.

Documentation/devicetree/bindings/pinctrl/rockchip,pinctrl.txt

-* Rockchip Pinmux Controller
-
-The Rockchip Pinmux Controller, enables the IC
-to share one PAD to several functional blocks. The sharing is done by
-multiplexing the PAD input/output signals. For each PAD there are several
-muxing options with option 0 being the use as a GPIO.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The Rockchip pin configuration node is a node of a group of pins which can be
-used for a specific device or function. This node represents both mux and
-config of the pins in that group. The 'pins' selects the function mode(also
-named pin mode) this pin can work on and the 'config' configures various pad
-settings such as pull-up, etc.
-
-The pins are grouped into up to 5 individual pin banks which need to be
-defined as gpio sub-nodes of the pinmux controller.
-
-Required properties for iomux controller:
-  - compatible: should be
-		"rockchip,px30-pinctrl":    for Rockchip PX30
-		"rockchip,rv1108-pinctrl":  for Rockchip RV1108
-		"rockchip,rk2928-pinctrl":  for Rockchip RK2928

-
-Optional properties for iomux controller:
-  - rockchip,pmu: phandle referencing a syscon providing the pmu registers

-
-Deprecated properties for iomux controller:
-  - reg: first element is the general register space of the iomux controller
-	 It should be large enough to contain also separate pull registers.
-	 second element is the separate pull register space of the rk3188.
-	 Use rockchip,grf and rockchip,pmu described above instead.

-Required properties for gpio sub nodes:
-See rockchip,gpio-bank.yaml

-Required properties for pin configuration node:
-  - rockchip,pins: 3 integers array, represents a group of pins mux and config

-    The MUX 0 means gpio and MUX 1 to N mean the specific device function.
-    The phandle of a node containing the generic pinconfig options
-    to use, as described in pinctrl-bindings.txt in this directory.

+
+description: |
+  The Rockchip Pinmux Controller enables the IC to share one PAD
+  to several functional blocks. The sharing is done by multiplexing
+  the PAD input/output signals. For each PAD there are several muxing
+  options with option 0 being used as a GPIO.
+
+  Please refer to pinctrl-bindings.txt in this directory for details of the
+  common pinctrl bindings used by client devices, including the meaning of the
+  phrase "pin configuration node".
+
+  The Rockchip pin configuration node is a node of a group of pins which can be
+  used for a specific device or function. This node represents both mux and
+  config of the pins in that group. The 'pins' selects the function mode
+  (also named pin mode) this pin can work on and the 'config' configures
+  various pad settings such as pull-up, etc.
+
+  The pins are grouped into up to 9 individual pin banks which need to be
+  defined as gpio sub-nodes of the pinmux controller.
