An example where this is an issue is in mt8192.dtsi, which has "sys_ck", "ref_ck", "xhci_ck" and would cause dtbs_check warnings. Change the clock list in a way that allows the middle optional clocks to be missing, while still guaranteeing a fixed order. The "ref_ck" is kept as a const even though it is optional for simplicity, since it is present in all current dts files. Signed-off-by: Nícolas F. R. A.
