Hm. Then you don't need a chip-select, and SPI driver must understand this case. When SPI controller has no "gpios" property, it should just ignore any chip-select toggling operations. As an implementation example you can use this patch: http://patchwork.ozlabs.org/patch/12499/ grep for "SPI w/o chip-select line." -- Anton Vorontsov email: cbouatmai...@gmail.com irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
