This commit includes some revisions to the spinel protocol, including
the addition of several new properties. It also includes some minor
updates to the SPI protocol, which should reduce ambiguity.
The new properties haven't been implemented in `ncp_base.cpp` yet,
but that will be comming soon.
`syslog()` and `fprintf()` are not async-signal-safe. They can (and
do) cause deadlocks under various circumstances.
This change replaces the calls to these functions with calls to
`write()`. It also adds a watchdog of sorts to the `signal_critical()`
handler to make sure that even if we call some functions that
are not async-signal-safe that we will at least terminate eventually.
This commit makes sure that the specified delay period between
the assertion of C̅S̅ and the start of the SPI clock is enforced.
In order for this to work, both the delay part and the data part
must be in the same `ioctl()` call. The previous code (which used
two `ioctl()` calls) was entirely broken.
The trick is that not all Linux SPI drivers support multi-part
SPI transactions. When `spi-hdlc-adapter` is used with such
devices, the `--spi-cs-delay=0` argument must be added. This causes
the delay part of the transaction to be omitted entirely.
This change contains changes to both `ncp_spi.*` and
`spi-hdlc-adapter.c`, based on experience with using both on actual
hardware. These changes fix a handful of critical bugs and also adds a
work-around (`--spi-align-allowance`) for naughty SPI-slave hardware.
A more through code review with @abtink revealed several bugs
in the previous implementation. This commit addresses these issues.
Additional changes will likely be necessary once we are able to test.
`spi-hdlc-adapter` is an adapter tool for using a SPI interface as if
it were an HDLC-lite encoded bidirectional asynchronous serial stream.
It uses the SPI protocol outlined in [Appendix A.2][1] of the Spinel
protocol document.
Note that since we don't have a slave implementation of this protocol,
this adapter hasn't been well tested yet. You have to start somewhere.
