Now that all files were converted to ReST format, rename them
and add an index.

docs: hwmon: convert remaining files to ReST format

2019-04-17T17:36:05+00:00

Convert all other hwmon files to ReST format, in order to allow
them to be parsed by Sphinx.

hwmon: (ltc4245) move header file out of I2C realm

2017-06-12T00:08:19+00:00

include/linux/i2c is not for client devices. Move the header file to a
more appropriate location.

hwmon: (ltc4245) Expose all GPIO pins as analog voltages

2010-08-14T19:08:49+00:00

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).

hwmon: (ltc4245) Read only one GPIO pin

2010-05-27T17:59:02+00:00

Read only one of the GPIO pins as an analog voltage. The ADC can be
switched to a different GPIO pin at runtime, but this is not supported.

Previously, this driver would report the analog voltage of the currently
selected GPIO pin as all three GPIO voltages: in9_input, in10_input and
in11_input.

ltc4215/ltc4245: Discard obsolete detect methods

2009-10-04T20:53:42+00:00

There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.

So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.
