[PATCH 0/7] alpha: marvel: environmental sensors

[Matt Turner <mattst88@gmail.com>]

The service processors of the Marvel AlphaServers (GS1280, ES80, ES47)
monitor temperatures, fans, voltages and power supplies. Linux can't read
these sensors, and the events the firmware raises when one changes state
are printed only with CONFIG_VERBOSE_MCHECK, and then decoded wrongly.

Patches 1 and 2 fix the event reporting. Patch 3 adds the SRM callback
that refreshes the readings of one config tree node, and patch 4
registers a platform device. Patch 5 is the hwmon driver, which polls.
Patches 6 and 7 make it reread the sensors and notify userspace when the
firmware reports an event.

The hwmon patches depend on the alpha ones, so I'd suggest the whole
series go through the alpha tree with an ack from Guenter.

Tested on an ES47, where sensors(1) shows the temperatures, fans,
voltages and power supply alarms. No environmental event fired during
testing, so patches 6 and 7 are only build tested.
