Can you please clarify how struct clk_parent_data can be used here? 

The zynqmp clock driver receives clock parent information from firmware and it is stored in struct clock_parent. In this patch, I added logic to get the parent clock reference from device tree and get corresponding clock name. Can you please explain how the struct clk_parent_data can be used for the same?

Thanks,
Naman
