By using IOMUX instead of GPIO Matrix for UART, it is now possible on ESP32 boards to use the UART as a wake up source even if it is not used as a console. For other boards where this issue was not present, using IOMUX has the advantage to be faster than using GPIO matrix, so a highest baudrate can be used
soc
The soc component provides hardware description for targets supported by ESP-IDF.
- `xxx_reg.h` - defines registers related to the hardware
- `xxx_struct.h` - hardware description in C `struct`
- `xxx_channel.h` - definitions for hardware with multiple channels
- `xxx_caps.h` - features/capabilities of the hardware
- `xxx_pins.h` - pin definitions
- `xxx_periph.h/*.c` - includes all headers related to a peripheral; declaration and definition of IO mapping for that hardware
