The clocks consist of a simple gate, a divider and a mux. The mux parents are not documented in the public S805 datasheet [0], so I had to use a bit of math and take the vendor kernel as reference [1] to find the actual parent clocks. Some mux parents cannot be divided down without remainder to the target clocks (as expected by the vendor NAND driver) these clocks have the ROUND_CLOSEST flag set.
