Hey Joachim,
I've noticed that my Hitex LPC4350 doesn't boot with latest next.
Here's the bootlog,
with lpc18xx_defconfig.
Thanks for reporting.
The 'would create circular parent' message doesn't seem to exist in
v4.5rc and seem to have been added by 858d58815 'clk: avoid circular
clock topology'.
Does it help to revert that commit? if not could you bisected it?
regards,
Joachim Eastwood

Hey Joachim,
I've noticed that my Hitex LPC4350 doesn't boot with latest next.
Here's the bootlog,
with lpc18xx_defconfig.
Thanks for reporting.
The 'would create circular parent' message doesn't seem to exist in
v4.5rc and seem to have been added by 858d58815 'clk: avoid circular
clock topology'.
Does it help to revert that commit? if not could you bisected it?
Indeed, reverting 858d58815 works, and allows to boot the board.
(BTW: forgot to mention that you need to apply
"ARM: fix __start_rodata_section_aligned on XIP" as !MMU build seems
broken on linux-next without it).

I have now replied on the clk patch which broke lpc18xx with you on
cc, so we'll take it from there.

Ok, I see. It is been while since I have tried booting next.
