From: Jonathan Marek <jonathan@marek.ca>
[ Upstream commit 667f39b59b494d96ae70f4217637db2ebbee3df0 ]
Fix the parents and set BRANCH_HALT_SKIP. From the downstream driver it should be a 500us delay and not skip, however this matches what was done for other clocks that had 500us delay in downstream.
