Clean up initialization of com_regs structure, in preparation for
some additional changers.

Change <machine/bus.h> to <sys/bus.h> throughout.

Adjust sc_frequency in MD attachment as quirks.
It is not applicable to all 1665x variants.

so needs to investigate why we have to divide sc_frequency by four
to get right baud rate on IOBlix com. (firmware sets MCR_PRESCALE?)

Fix compilation warnings and errors with amigappc.

Use lwp_getpcb() on m68k ports, clean from struct user usage.

Remove clause 3 and 4 from TNF licenses

Split device_t and softc for all com(4) devices (well, everything that
uses a com_softc backend). Use proper types and ansify where appropriate.

Fix reference to sc_dev so that this builds again.

Use pmf_device_register1() instead of shutdownhook_establish() to
register com_cleanup() as the shutdown hook.

Add a generic suspend routine. Suspend and resume com@isa.

Protect against dereferenc

register com_cleanup() as the shutdown hook.

Add a generic suspend routine. Suspend and resume com@isa.

Protect against dereferencing a NULL softc in comioctl().

Destroy both a mutex and a callout in com_detach().

Cosmetic: use aprint_*_dev(). Use PMF_FN_ARGS, PMF_FN_PROTO.

Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Approved by core@. Fixes PR port-evbmips/32362.

Actually probe the hardware.
This is for HyperCom 3i slaveboards (to be done soon) that might or might not

Matthias Scheler for pointing this out).
