[RFC PATCH 0/2] Propose critical clocks

Hi,

this proposal is to mark clocks as critical. It is somehow inspired by
the regulator-always-on property. Since sometimes we can end in circular
dependcies if we wanna solve the dependcies for a specific clock
provider.

The property is generic so it can be used by every hw clock provider. So
it can be seen as generic implementation to [1].
