Board description describes the hard part of chip (PS) but programmable logic (PL) part is not described in this file. But clocks on the board are not only connected to PS but also wired to PL. And because two revisions are available where revA is using one si5332 and revB multiple clock chips using the same clock labels helping with keeping only one device tree overlay which targets PL. That's why synchronize clock labels and use labels from revB which are more generic. Unfortunately if there is driver for si5332 chip split could happen again but it is still worth to do it now and solve this issue when occurs.
