I'd request adding an explict documents for why need CLK_IS_CRITICAL flag
(there are more place, I won't add comments)
Can you check this one? I think it's probably not necessary here,
I can understand your concern of afraid of serial console breakage once clk
driver merged, since we already enabled uart driver and using a dummy clk..
I think we probably could handle this carefully, sending an incrimental
patch of uart to enable clk along with clk merged..
