 1.10  21-Jun-2021  christos fix proplib deprecation
 1.9  27-Jan-2021  thorpej branches: 1.9.4;
Use DEVICE_COMPAT_EOL.
 1.8  25-Jan-2021  thorpej Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.
 1.7  17-Jan-2021  thorpej Use designated initializers and a consistent termination style in
compat_data[].
 1.6  23-Dec-2020  jdc Handle pins that represent alerts.
split out common code for alert and indicator pins
change the previously debug-only callout to work for alerts too
split out common code for alerts in refresh and in callout
While here, remove redundant variable used for checking sysmon setup.
 1.5  06-Dec-2020  jdc Don't read from the chip when matching, fail the attach instead (requested
by jmcneill). Reverts previous.
 1.4  05-Dec-2020  jdc Return "match_result", not "1". Pointed out by jmcneill.
 1.3  05-Dec-2020  jdc When matching, try a read in case this is an optional device and isn't
actually present.
Make sure that we set sc->sc_sme to NULL in failure cases and when we
detach in order to avoid calling sysmon_envsys_unregister() with an
invalid struct.
 1.2  31-Oct-2020  jdc branches: 1.2.2;
Detach led's and sysmon in our detach routine.
 1.1  29-Oct-2020  jdc Add a driver for the PCF8574 I/O expander, used as a GPIO in some sparc64
hardware.
The driver currently handles pins configured as LED or INDICATOR and adds
them to the LED and sysmon_envsys subsystems, respectively.
 1.2.2.3  03-Apr-2021  thorpej Sync with HEAD.
