3910c35193 dts: fix u-blox sara r4 compatible
It should be "u-blox,sara-r4", because the vendor prefix for this
company is "u-blox", not "ublox".

6d273f49bd pm: fix incorrect usages of PM_DEVICE_STATE_OFF
According to the documentation the OFF state has to be used when the
devices is fully turned off, ie, power removed. Most drivers were using
a sort of fall-through for all non-active states, leading to behaviors
not following the specifications.

d41dadc569 pm: rename PM_DEVICE_STATE_SUSPEND to PM_DEVICE_STATE_SUSPENDED

56a35e5682 pm: converge to suspend state for low power modes
The difference between low power and suspend states is a thin blur line
that is is not clear and most drivers have used indistinctly. This patch
converges to the usage of the suspend state for low power, since
contrary to the low power state, it is used by both system and runtime
device PM. The low power state is still kept, but its future is unclear
and needs some discussion.

1a4cb7e0e3 drivers: modem: add modem_cmd_send_ext()
There are currently modem_cmd_send() and modem_cmd_send_nolock()
functions, each with slightly different behavior regarding acquiring (or
not) sem_tx_lock. Introduce a generic function that will allow caller to
select behavior using flags.

While at it, add possibility to disable setting and unsetting command
handlers. This will be useful in situations when there are multiple
replies expected one after the other coming as a response to single
command. This is the case for example with ESP-AT driver, which expects
following data as response to AT+CIPSEND command:

  OK
  >

where 'OK' is handled by static CMD_RESP (so releasing response
semaphore right away), while '>' is handled by dynamic
CMD_HANDLER (which is releasing another semaphore). Keeping command
handlers in place allows to receive '>' without race condition because
of small period of time where command handlers are not set.

Convert modem_cmd_send_nolock() and modem_cmd_send() to static inline
functions, as they are just a specific invocation of
modem_cmd_send_ext() function.

28ac1f70bf drivers: modem: gsm_ppp: proper attach retry
In a previous commit, a check was added to ensure modem was properly
attached to packet service before initializing PPP. Failure to perform
this check can lead to the dreaded 'NO CARRIER' issue.

While this is a nice idea, the implementation was lacking because when
the check failed, the entire modem initialization procedure was
restarted from square one. For modems/bearers that were slow to attach,
this is potentially disastrous. The proper solution is to loop only the
'AT+CGATT?' part until it succeeds, or fails N times.

This commit implements this looping behavior (using the work queue).

4626a577c4 drivers: modem: gsm_ppp: Kconfig for autostarting ppp
Autostarting PPP is far from controversial. There are many, many reasons
someone could have for wanting to control exactly when PPP starts. Power
management, NET_EVENT race condition avoidance and any application not
requiring constant and instant use of networking just to name a few.

This commit introduces a Kconfig setting, GSM_PPP_AUTOSTART, which
controls whether gsm_ppp should connect and initialize PPP at boot. It
is set to "y" as default to minimize surprises for legacy code.

254c126236 drivers: modem: optional factory reset at modem boot
Some modems, under some conditions, have a tendency to get stuck without
a connection due to cached state. We have observed this on some Simcom
LTE modems after large cellular outages. The modems are unable to escape
their cached state for some reason unless they're factory reset (or a
cache clearence is forced in some other way).

This commit allows for the modem to be factory reset at each boot. This
minimizes dependencies on external state by ensuring each power-up is as
similar as possible.
