5 Espressif Digital to Analog converter (DAC) control node
6 is part of the RTC low-power domain and belongs to the SENSE
10 Two GPIO pads can only be connected to the DAC peripheral.
13 - GPIO25 as DAC channel 1
14 - GPIO26 as DAC channel 2
16 ESP32-S2 pads
17 - GPIO17 as DAC channel 1
18 - GPIO18 as DAC channel 2
20 To enable the DAC peripheral it must be enabled in the board
23 &dac {
27 To specify the DAC channel to use, dts overlay must include
28 properties 'dac-channel-id', which uses zero based channel index.
29 Variable 'dac-resolution' must be also specified, although ESP32
30 only supported resolution is 8bits.
