weird size, shouldn't this be 0xd000 then the size would be exactly
52KiB
okay
btw, the reason here is that when you call devm_ioremap_resource(), that
will call resource_size() which does:
size = res->end - res->start - 1;
so you need this extra 1 on the size when passing it via DT.
agreed.
Another thing: am437x has 4 instances of this IP, why are you adding
only one ?
AM437x has got only 2 instances. I have verified only one on HAPS so
adding only one.
weird, on my TRM I see for dwc3 but 2 PHYs.
Please confirm whether you are looking at am437x TRM or dra7x TRM?
dra7x has 4 dwc3 and 2 internal phys and 2 external phys
And why aren't you pasing the PHY nodes here ? The device
won't work without its PHYs.
Yes true, again in HAPS I didnt have any PHY configuration to be done.
alright, but we should still pass the PHY right ? once silicon comes,
we want this to work without any further changers.
okay will add phy nodes and 2 instances of dwc3.
