Same comment as vencsys patch: wpesys_vpp0 and wpesys_vpp1 look the same.
Are they identical hardware blocks? Are different compatible strings
really needed?

I suggest adding clock-output-names to the device tree, and patching
mtk_clk_register_gates_with_dev() to try to get a clock name from the
device tree, and falling back to the predefined name in the list.
Something like:
