19 * @brief Get a PSEL value out of a foo-gpios or foo-pin devicetree property
21 * Many Nordic bindings have 'foo-pin' properties to specify a pin
22 * configuration as a PSEL value directly instead of using a 'foo-gpios'
25 * It would be better to use 'foo-gpios' properties instead. This type
26 * of property is more in line with the recommended DT encoding for GPIOs.
28 * To allow for a smooth migration from 'foo-pin' to 'foo-gpios', this
30 * using whichever one of 'foo-gpios' or 'foo-pin' is in the DTS.
34 * - NRF_DT_PSEL_CHECK_*() to check the property configuration at build time
35 * - NRF_DT_GPIOS_TO_PSEL() if you only have a 'foo-gpios'
