For the XBurst SoCs, pin control is tightly bound with GPIO ports. All pins may
be used as GPIOs, multiplexed device functions are configured within the
GPIO port configuration registers and it is typical to refer to pins using the
naming scheme "PxN" where x is a character identifying the GPIO port with
which the pin is associated and N is an integer from 0 to 31 identifying the
pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
PB31 is the last pin in GPIO port B. The jz4740 contains 4 GPIO ports, PA to
PD, for a total of 128 pins. The jz4780 contains 6 GPIO ports, PA to PF, for a
total of 192 pins.

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.
