- qcom,no-dynamic-asid:

		  Clients that uses the dynamic domains will have an unique asid

		  per each domain and all domains can share the same context bank.

		  When ASID based invalidation is used, on some hardware revisions,

		  as a result of multiple ASID's associated with the same context

		  bank, TLB entries are not invalidated properly. On such systems,

		  we can choose to have a single ASID associated with all domains

		  for a context bank.
