Is managing the reset line actually optional though? I can't test atm as I don't have
access to my board, but quite often if the IP's aren't taken out of reset reads / writes
to the perhpiheral will hang the SoC.
Yes and No.
AFAIK reset line is optional on SOCs like 7108, 7141.
I think having the driver function without reset might is a value add in
case we plan to reuse the mainline driver for these SOCs.
On latest ARM SOCs with SBC the IRB IP is moved to SBC and held in reset.
Am not sure, if the reset line is optional in next generation SOCs?
If managing the reset line isn't optional then I think the correct fix is to add
depends on RESET_CONTROLLER in the kconfig.
I agree.
This would make the COMPILE_TEST less useful though.
thanks,
srini
This will then do the right thing for randconfig builds as well.
regards,
Peter.
