Some clocks may have multiple downstream users that need to request a higher clock rate. ?Shared bus clocks provide a unique shared_bus_user clock to each user. ?The frequency of the bus is set to the highest enabled shared_bus_user clock, with a minimum value set by the shared bus. ?Drivers can use clk_enable and clk_disable to enable or disable their requirement, and clk_set_rate to set the minimum rate.

A later patch in the series removes the ifdef. Might as well remove it here. Also, should be c->set = true, which that patch also does. :) With that fixed: Acked-by: Olof Johansson <redacted>
