directory provides configuration templates for all documented

"dir" (transmit/receive direction), comparator values ("cmp_l"

* Catch the slave interrupts and send appropriate i2c_slave_events to the backend.
Note that most hardware supports being master _and_ slave on the same bus. So,
if you extend a bus driver, please make sure that the driver supports that as
well. In almost all cases, slave support does not need to disable the master
functionality.
Check the i2c-rcar driver as an example.

results in the system call being skipped immediately.
- seccomp syscall wired up
For best performance, an arch should use seccomp_phase1 and
seccomp_phase2 directly. It should call seccomp_phase1 for all
syscalls if TIF_SECCOMP is set, but seccomp_phase1 does not
need to be called from a ptrace-safe context. It must then
call seccomp_phase2 if seccomp_phase1 returns anything other
than SECCOMP_PHASE1_OK or SECCOMP_PHASE1_SKIP.
As an additional optimization, an arch may provide seccomp_data
directly to seccomp_phase1; this avoids multiple calls
to the syscall_xyz helpers for every syscall.
