Thanks for your patch, which is now commit 5a230524f87926f2 ("ARM:
dts: Use simple-pm-bus for genpd for am3 l4_wkup") in v5.11-rc1.
I have bisected a boot failure on BeagleBone Black to this commit.
Reverting this commit on top of a v5.11-rc3-based tree does not help.
With "earlycon keep_bootcon", I do get some output, the last line is
l4-wkup-clkctrl:00d4:0: failed to disable
I have attached the kernel output of the previous (good) commit,
and the failing one.
Do you have a clue?
Thanks!
