Hi! This series adds the option for declaring clocks as "ignore-unused", i.e. clocks that will not be turned on if not used, but also not turned off if unused. It also enables this option for the RWDT clocks in (almost) all SoCs. The point of this is to allow a WDT that has been enabled by the bootloader to survive these events: - deferred probing of the WDT device, which can lead the clock driver to disable the WDT clock until the WDT is re-probed, giving it a blind spot - probe failure in the WDT driver There are a number of SoCs that have the RWDT clock already declared as critical (i.e. turn it on even if it is off _and_ unused). I don't know if that is because there was no option for ignore-unused before, or if the behavior of turning the clock on even if neither the bootloader nor anything in the kernel has asked for it is actually desired. If it's the former, these SoCs also have to be converted to the new mechanism.
