14 | Description | |
15 | ----------- | |
16 | ||
17 | The WM835x series of PMICs include an AUXADC which can be used to | |
18 | monitor a range of system operating parameters, including the voltages | |
19 | of the major supplies within the system. Currently the driver provides | |
20 | simple access to these major supplies. | |

25 | Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC | |
26 | is referenced to the system VRTC. |
