As I made significant changes to the pc87427 driver, I'll be
maintaining it for the year to come.Signed-off-by: Jean Delvare
-
The sysfs file removal code is the same in the probe error path and in
the remove function, so move it to a separate function to avoid code
duplication.Signed-off-by: Jean Delvare

Add support for the 6 temperature monitoring channels of the PC87427.
Note that the sensors resolution can vary, and I couldn't find a way
to figure it out, so we might have to compensate in user-space.Signed-off-by: Jean Delvare

The second logical device contains the voltage and temperature
registers. We have to extend the driver to support a second logical
device before we can add support for these features.Signed-off-by: Jean Delvare

Add initial support for PWM outputs of the PC87427 Super-I/O chip.
Only mode change and manual fan speed control are supported. Automatic
mode configuration isn't supported, and won't be until at least one
board is known, which makes uses of the PWM outputs.Signed-off-by: Jean Delvare

Most fan input pins of the PC87427 can have alternate functions.
Update the driver to check the configuration register and only support
fan inputs which are really used for fan monitoring.Signed-off-by: Jean Delvare

Add support for W83667HG-B (very similar to the W83667HG).

- Moved fan pwm register array pointers into per-instance data.
- Only read fan pwm data for installed/supported fans.
- Update fan max output and fan step output information from data in
registers.
- Create max_output and step_output attribute files only if respective
fan pwm registers exist.Signed-off-by: Guenter Roeck

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.Signed-off-by: Steve Glendinning

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.Signed-off-by: Jean Delvare

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
and LTC4245 drivers. currX_alarm is supported by the LTC4261 driver.Signed-off-by: Guenter Roeck

* The dev variable is never used.

Some voltage sensors can be wired internally to the IT87xxF chip's own
power supply channels. In that case, we can inform user-space that the
wiring is known by exporting proper labels for these sensors.Signed-off-by: Jean Delvare

There is a shutdown feature at suspend it can be enabled to
reduce current consumption and resume it can be switched off.Signed-off-by: Shubhrajyoti Datta

Add back the power interface we lost due to a slight misunderstanding of
the maintainers wishes.Signed-off-by: Alan Cox
Signed-off-by: Jean Delvare -
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).Signed-off-by: Ira W. Snyder

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.Signed-off-by: Jean Delvare

rwsem: wake queued readers when writer blocks on active read lockmade this change:
- (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK))
- /* Someone grabbed the sem already */
+ rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS)
