About the SFDP patches they are still RFC so yes, they can wait, no
problem with that. Anyway I was working on them this afternoon so they
are not finalized yet.

However the first 3 patches of the series, especially patch
"mtd: spi-nor: introduce more SPI protocols and the Dual Transfer Mode",
are needed as a base to fix other long time pending issues.

Those patches are available from both the github/spi-nor and linux-next
tree. So I think Ludovic can rebase his patches, test them then send v3
to the linux-mtd mailing list with the relevant ChangeLog in the cover
letter.

For your information:

2017-01-25 https://patchwork.ozlabs.org/patch/719777/
2017-03-22 https://patchwork.ozlabs.org/patch/742376/

Sorry but I think the patch changing the 3rd argument of spi_nor_scan()
has precedence over newer patches in the queue to be mainlined.

Best regards,

Cyrille
