SMSC's EMC2103 family of temperature/fan controllers have 1
onboard and up to 3 external temperature sensors, and allow
closed-loop control of one fan.  This patch adds support for
them.

Fault files are for hardware failures that can be reported. So far
we've seen chips reporting such failures for temperature sensors and
fans, but not for voltages. Remove in[0-*]_fault for now. It can be
added back later if really needed, but I doubt it.

Add currX_alarm, currX_min_alarm, currX_max_alarm and currX_beep
attributes to the hwmon sysfs API.

currX_min_alarm and currX_max_alarm are already supported by the LTC4215

Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.

The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.

Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

It's not OK to call platform_device_add_resources() multiple times
in a row. Despite its name, this functions sets the resources, it
doesn't add them. So we have to prepare an array with all the
resources, and then call platform_device_add_resources() once.

Before this fix, only the last I/O resource would be actually
registered. The other I/O resources were leaked.

 rwsem: wake queued readers when writer blocks on active read lock

made this change:

-               /* Someone grabbed the sem already */
+           rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS)
+               /* Someone grabbed the sem for write already */

RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked
at the low order 32-bits. The new code needs to see all 64 bits.
