OK, so you need a driver or subsystem that implements FPGA updates then - depending on what that looks like the FPGA or MTD subsystems seem likely to be candidates, or perhaps the MFD for your device should provide something as part of the core functionality. All the issues I raised earlier apply here, spidev is rarely a good idea for production use and certainly not in cases where there are actual drivers sharing the device. > > Please don't send content free pings and please allow a reasonable time > > for review.

You need to take this up with your mail provider. --PMULwz+zIGJzpDN9 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmDQpR4ACgkQJNaLcl1U h9Ba4Qf+PH41WaBq9wZNKOE1ZjTtGN7+wfby5RYep9tzn5fPAz1IYQuGA2knCur2 KYdhUUVvDbuc3VN5yQArkxzfN0VLyRXqGYAiEeB23ik8Kjz/Hx6643twL8q+VoPN Wc917WnZkTj4GjtYdj/dnTWI+hZ1M1C4Z8FDIKOWJYDCge0Cov2RPSbDWO7gy5St BuHC2u5n0QJaR+HQQOHaVPh0k3KJLQHpc7YPq5bofHhpX65Hea8NRE+PQEkfFaJr 2uJTH1s3fngZsbSIEqd49jj2owyZw26IEgX+TuMsPtEfAB9jq+2PNqv2MrLbqaXT gfoGrlSNWLiW/7chykCXvbdkFOcXKA== =ymgs -----END PGP SIGNATURE----- --PMULwz+zIGJzpDN9--
