Great and good to hear things are working with only dts changes now :) Yes let's try to get these merged. > There is one issue that I have run into while testing this series on > the latest kernel.

I wonder the following commit in v5.8-rc3 might help with this though: 5ce8aee81be6 ("bus: ti-sysc: Flush posted write on enable and disable") I was seeing that occasionally with mcspi, but never had anything reproducable.
