As this commit is not in Linus' tree yet, we can't point to its commit ID.

> check NFC busy by nfc SR instead of NFC cmd regs. So we don't need to
> map NFC cmd registers to include NFCBUSY bit.
> That means we only need map 0x08000000 instead of 0x10000000 for NFC
> cmd regs.

> This patch reduce the NFC cmd regs map for sama5d3 & sama5d4.

I'll modify the commit message to adapt the commit ID and send it when
the patch is merged (probably after 4.0-rc1).

Thanks, best regards,
