Hi all, Probably, I should ask my quesiton on some SPI dedicated mailing lists, however, the borders of "newbiness" are hard to estimate.
As I can see, most SPI controller drivers currently attempting to control CS (SS) line by themselves, usually enabling it just before spi_message processing and disabling after it. Therefore, all transfers within a message are going as one atomic transaction. However, what should I do, if device requires CS to be triggered to active state and remained active until device will trigger IRQ, indicating that it awoke and ready for transaction? I presume, that I need some kind of manual CS control. How does it fit into general SPI subsystem paradigm and how I can implement it? -- Best regards, Sergii Kovalchuk -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
