This is the bulk of pin control changes for the v3.20 cycle: 

- Framework changes and enhancements:
   - Passing -DDEBUG recursively to subdir drivers so we get
     debug messages properly turned on.
   - Infer map type from DT property in the groups parsing code
     in the generic pinconfig code.
   - Support for custom parameter passing in generic pin config.
     This is used when you are using the generic pin config, but
     want to add a few custom properties that no other driver
     will use.
 
 - New drivers:
   - Driver for the Xilinx Zynq
   - Driver for the AmLogic Meson SoCs
 
 - New features in drivers:
   - Sleep support (suspend/resume) for the Cherryview driver
   - mvebeu a38x can now mux a UART on pins MPP19 and MPP20
   - Migrated the qualcomm driver to generic pin config handling
     of extended config options in the core code.
   - Support BUS1 and AUDIO in the Exynos pin controller.
   - Add some missing functions in the sun6i driver.
   - Add support for the A31S variant in the sun6i driver.
   - EMEv2 support in the Renesas PFC driver.
   - Ass support for Qualcomm MSM8916 in the qcom driver.
 
 - Deleted features
   - Drop support for the SiRF Marco that was never released to
     the market.
   - Drop SH7372 support as the support for this platform is
     removed from the kernel.

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, a group, or a list of pins or groups. This configuration can include the
mux function to select on those pin(s)/group(s), and various pin configuration
parameters, such as pull-up, drive strength, etc.
PIN CONFIGURATION NODES:
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 gpio pins affected by the properties specified in
this subnode. Valid pins are:

Please refer to pinctrl-bindings.txt in this directory for details of the

Zynq's pin configuration nodes act as a container for an arbitrary number of
subnodes. Each of these subnodes represents some desired configuration for a
pin, a group, or a list of pins or groups. This configuration can include the
mux function to select on those pin(s)/group(s), and various pin configuration
parameters, such as pull-up, slew rate, etc.
Each configuration node can consist of multiple nodes describing the pinmux and
pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
The name of each subnode is not important; all subnodes should be enumerated
and processed purely based on their content.
Required properties for pinmux nodes are:
- groups: A list of pinmux groups.
- function: The name of a pinmux function to activate for the specified set
of groups.
Required properties for configuration nodes:
One of:
- pins: a list of pin names

low-power-disable, low-power-enable
Valid arguments for 'slew-rate' are '0' and '1' to select between slow and fast
respectively.

/*
* The available pins are organized in banks (A,B,C,D,E,X,Y,Z,AO,
* BOOT,CARD for meson6 and X,Y,DV,H,Z,AO,BOOT,CARD for meson8) and
* each bank has a variable number of pins.
*
* The AO bank is special because it belongs to the Always-On power
* domain which can't be powered off; the bank also uses a set of
* registers different from the other banks.
*
* For each of the two power domains (regular and always-on) there are
* 4 different register ranges that control the following properties
* of the pins:
* 1) pin muxing
* 2) pull enable/disable
* 3) pull up/down
* 4) GPIO direction, output value, input value
*
* In some cases the register ranges for pull enable and pull
* direction are the same and thus there are only 3 register ranges.
*
* Every pinmux group can be enabled by a specific bit in the first
* register range of the domain; when all groups for a given pin are
* disabled the pin acts as a GPIO.
*
* For the pull and GPIO configuration every bank uses a contiguous
* set of bits in the register sets described above; the same register
* can be shared by more banks with different offsets.
*
* In addition to this there are some registers shared between all
* banks that control the IRQ functionality. This feature is not
* supported at the moment by the driver.
