So it's getting an invalid clk pointer in sysc_enable_opt_clocks.

It looks strange to recursively go through simple_pm_bus_probe() here four times before getting to the ti,sysc driver.
Full test log link,
What is the easiest way to find out how long this job has been failing, and what the last successful build was?
It is not reproducible easily and I have checked when it got started but failed to find it. Because on v6.0-rc3 kernel the x15 did not boot pass.
