Reset signals for whole -+standalone chips are most likely better represented as GPIOs, although there -+are likely to be exceptions to this rule. -+ -+Hardware blocks typically receive a reset signal.

The length (number of cells) and semantics of the reset specifier -+are dictated by the binding of the reset provider, although common schemes -+are described below. -+ -+A word on where to place reset signal consumers in device tree: It is possible -+in hardware for a reset signal to affect multiple logically separate HW blocks -+at once. In this case, it would be unwise to represent this reset signal in -+the DT node of each affected HW block, since if activated, an unrelated block -+may be reset. Instead, reset signals should be represented in the DT node -+where it makes most sense to control it; this may be a bus node if all -+children of the bus are affected by the reset signal, or an individual HW -+block node for dedicated reset signals.
