Subject[PATCH v1] clk: qcom: Make common clk_hw registrations
Date
Several clock controller drivers define a list of clk_hw devices, and then
register those devices in probe() before using common code to process the
rest of initialization. Extend the common code to accept a list of clk_hw
devices to process, thus eliminating many duplicate implementations.
