5 The Renesas RA pin controller is a node responsible for controlling
6 pin function selection and pin properties, such as routing a SCI0 RXD
16 All device pin configurations should be placed in child nodes of the

41 The 'sci0_default' child node encodes the pin configurations for a
42 particular state of a device; in this case, the default (that is, active)
45 As shown, pin configurations are organized in groups within each child node.
46 Each group can specify a list of pin function selections in the 'psels'
49 A group can also specify shared pin properties common to all the specified
50 pins, such as the 'input-enable' property in group 2. Here is a list of
51 supported standard pin properties:
53 - bias-disable: Disable pull-up/down (default, not required).
54 - bias-pull-up: Enable pull-up resistor.
55 - input-enable: Enable input from the pin.
56 - drive-strength: Set the drive strength of the pin. Possible
57 values are: low, medium, highspeed-high, high.
