These are on top of your series as those are required to make things actually work as expected. Which reminds me, i was wondering how to best move that forward. Could you pick this one up to include it in the next round of your series?

Aka if there needs to be a v2 (depending on the clock maintainers) I can pick that up as part of it. Otherwise we'll just need to ping the clock-maintainers separately on this patch if necessary.

The clock branches leading to sclk_spdif and sclk_spdif_8ch on RK3288 SoCs only feed those clocks, allow those clocks to change their parents all the way up the hierarchy.
