Yes, you'd able to do it, but there is no such thing as SPI CS engine, yet. See the two options of how we can implement it: http://www.mail-archive.com/[email protected]/msg34738.html Grant said that he like option "2.", but also said that we might want to modify SPI requests (messages) before sending the data to the outside world. I think that the option "1." fits better for this task. Which means that implementation should be quite trivial -- just another spi master driver. > [...] the 8xxx SPI driver only looks for gpio functions. Yes, and we should consider removing the gpio stuff too. > Perhaps this is something that you are working on? No, I don't need the feature right now (i.e. no board that I'm working on needs this). But I know how to implement it (see the link above). -- Anton Vorontsov email: [email protected] irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list [email protected] https://lists.ozlabs.org/listinfo/linuxppc-dev
