GPIO drive strength flags
The drive strength flags are a Zephyr specific extension of the standard GPIO flags specified by the Linux GPIO binding. Only applicable for Espressif ESP32 SoCs. The interface supports two different drive strengths: DFLT - The lowest drive strength supported by the HW ALT - The highest drive strength supported by the HW
#define	ESP32_GPIO_DS_DFLT   (0x0U << ESP32_GPIO_DS_POS)
#define	ESP32_GPIO_DS_ALT   (0x3U << ESP32_GPIO_DS_POS)
