+title: ADC that forms part of an ASPEED server management processor.
+
+maintainers:
+ - Billy Tsai <billy_tsai@aspeedtech.com>
+
+description: |
+ • 10-bits resolution for 16 voltage channels.
+ • The device split into two individual engine and each contains 8 voltage
+ channels.
+ • Channel scanning can be non-continuous.
+ • Programmable ADC clock frequency.
+ • Programmable upper and lower threshold for each channels.
+ • Interrupt when larger or less than threshold for each channels.
+ • Support hysteresis for each channels.
+ • Built-in a compensating method.
+ • Built-in a register to trim internal reference voltage.
+ • Internal or External reference voltage.
+ • Support 2 Internal reference voltage 1.2v or 2.5v.
+ • Integrate dividing circuit for battery sensing.
