It wastes time. I got it. Thanks. Let me resend the patch with the change information.

This commit reverts commit 487dc7bb6a0c ("clk: sifive: fu540-prci: Declare static const variable 'prci_clk_fu540' where it's used"). For fixing W=1 kernel build warning(s) about ‘prci_clk_fu540’ defined but not used [-Wunused-const-variable=], the problem is that the C file of fu540 and fu740 doesn't use these variables, but they includes the header files. We could refine the code by moving the definition of these variable into fu540 and fu740 implementation respectively, instead of common core code, then we could still separate the SoCs-dependent data in their own implementation.
