/*
 * This file is created to fulfill the requirement of a pinctrl-N
 * property for nodes in the specific target overlay file.
 *
 * In the current implementation of samples, the specific peripheral
 * driver instance is initialized at runtime with a configuration
 * based on pin symbols defined in `nrfx_example.h`.
 *
 * To use values from specific property nodes from the device tree,
 * appropriate values for the `psels` property must be provided
 * instead of the dummy values defined in that file. Once done, these values
 * can be accessed from the device tree through using the API implemented in
 * `<zephyr/devicetree.h>` (see Zephyr’s doc: Devicetree access from C/C++).
 *
 * Here is a sample of extracting node `psels` values to initialize a peripheral
 * driver instance with a configuration based on those values:
 *
 * #define SPI_NODE DT_NODELABEL(spi1)
 * #define SPI_PINCTRL_NODE DT_CHILD(DT_PINCTRL_0(SPI_NODE, 0), group1)
 * #define SCK_PIN (DT_PROP_BY_IDX(SPI_PINCTRL_NODE, psels, 0) & 0x3F)
 * #define MISO_PIN (DT_PROP_BY_IDX(SPI_PINCTRL_NODE, psels, 1) & 0x3F)
 * #define MOSI_PIN (DT_PROP_BY_IDX(SPI_PINCTRL_NODE, psels, 2) & 0x3F)
