New drivers must use the the with_info() hardware monitoring API. The API use is inappropriate: _enable attributes are supposed to enable monitoring, not a power source. The hardware monitoring subsystem is responsible for hardware _monitoring_, not control. It can be tied to the regulator subsystem, but even that seems to be be inappropriate here. I think the driver should probably reside in drivers/net/pse-pd/. That doesn't mean it can not support hardware monitoring, but that isn't really the chip's primary functionality. Yes, I see that we already have ti,tps23861 in the hardware monitoring subsystem, but that may be just as wrong. I am copying the PSE subsystem maintainers and mailing list for advice. Thanks, Guenter
