Hi,

Tony et al , I am trying to run the 6.1.y branch on an AM3517-EVM.
There are two GPT that throw an error:
ti-sysc: probe of 48318000.target-module failed with error -16 ti-sysc: probe of 49032000.target-module failed with error -16
These two timers are in use as clocksource and clockevent reserved by timer-ti-dm-systimer.
I did some minor investigation and found sysc_check_active_timer() is returning the busy condition.
I tracked this back a bit further and found that if I revert commit a12315d6d270 ("bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific"), this error condition goes away.
It almost looks to me like sysc_check_active_timer is defaulting to -EBUSY when the SoC is not 3430, but the sysc_soc_match[] doesn't appear to match to AM3517.
I think the proper solution is to treat the AM35* as 3430. Do you agree with that approach?
If so, I'll submit a patch with a fixes tag. I am also wondering how far back I should mark the fixes tag.
Yes am3517 is very similar to 3430. Sounds like the patch would be needed also against the current kernels, right?
I submitted a patch against the mainline kernel [1] with fixes tags to hopefully back-port them to 6.1.y. Any feedback and/or assistance you can help to move them forward would be appreciated.
