40 ADC reference voltage supply
45 Enables synchronization of multiple devices that require simultaneous
46 sampling. A pulse is always required if the configuration is changed
47 in any way, for example if the filter decimation rate changes.
48 As the line is active low, it should be marked GPIO_ACTIVE_LOW.
53 spi-max-frequency: true
73 "^channel@([0-9]|1[0-5])$":
76 Represents the external channels which are connected to the device.
86 Unique name to identify which channel this is.
