That sounds like it is going to break normal chip select operation which doesn't seem like a good idea either. What exactly are you trying to do here? If you need to send some extra bytes at the end of a transfer why not just do that, or add an empty transfer with a delay. It's hard to see what more you could do with only control of the chip select... --4cv0JMvpEKiCIDl2 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJXFmcGAAoJECTWi3JdVIfQV3cH/13tX6IFbyU7cJBFsp94l8u0 RZ8ygWZrra/QQMyPguVMdheFO50a6wPZL1nZ0iPa2Zp8b0RUCjCuuDxtjoJf5QD6 39GH1LuyIK122A2S1DG5aRP8HjUtrOT5s1oE8IwGSTxSow9E60bJPOHoDt23uoFi EDa6F+MnQ0QhPSQhKdUEwVCrNCep+qEmQxOT83fei+xd3MFAFtb9vTACNaPexOO4 iRU94K2wUO1np7ug8M9Q4Sx5inkXh+Fy3Ug34x2fWG8prhqa/TDXXfu/IyfDwlpM 0UIWRQheG7zxMdGqGsXL84gI4k6mNZKn0f37vwmGV3ioan07BzSY+LkBREXpv7I= =FdXk -----END PGP SIGNATURE----- --4cv0JMvpEKiCIDl2-- -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
