Kernel driver wm8350-hwmon¶
Wolfson Microelectronics WM835x PMICs
Authors: Mark Brown <firstname.lastname@example.org>
The WM835x series of PMICs include an AUXADC which can be used to monitor a range of system operating parameters, including the voltages of the major supplies within the system. Currently the driver provides simple access to these major supplies.
Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC is referenced to the system VRTC.
