The current binding has been acked by Rob right? Assuming the new binding is acked/reviewed then that solution is fine. Otherwise, I still prefer two DTS files for the two different FPGA versions. At the least, please use ioremap for any pointers that you readl/writel here. Beyond that, we should have a fixed rate source clk somewhere in the software view of the clk tree, because that reflects reality. Hardcoding the parent rate in the structure works, but doesn't properly express the clk tree. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
