Hi Conor/Emil,
DT overlay is used to describe combinations of VF2 and hat. Do you have any comments on this patch ?
Up to Emil :)
I seem to recall that he said at the linux-riscv sync-up call that we have* that he was not in favour of overlays for hats like this. I'll let him confirm that though, I might very well be misinterpreting or misremembering what he said.
What probably meant was that I didn't want a bunch of different device trees for each combination board * hat. An overlay makes a lot more sense. However, looking through the kernel tree there is a surprising lack of overlays for hats committed already, so I suspect there is some sort of policy around overlays already in place.
Cheers, Conor.
