  Espressif's GDMA (General Direct Memory Access) Node

  General Direct Memory Access (GDMA) is a feature that allows
  peripheral-to-memory, memory-to-peripheral, and memory-to-memory
  data transfer at a high speed.

  The GDMA controller in ESP32-C3 has six independent channels,
  three transmit channels and three receive channels.

  Every channel can be connected to different peripherals.

  Peripherals with GDMA:
  * SPI2
  * UHCI0 (UART0/UART1)
  * I2S
  * AES
  * SHA
  * ADC

compatible: "espressif,esp32-gdma"
