Sebastian Reichel 09d9d82745 hwmon: (twl4030-madc) drop driver
This driver is no longer needed:

 * It has no mainline users
 * It has no DT support and OMAP is DT only
 * iio-hwmon can be used for madc, which also works with DT

Chris Packham 4abdf38d20 hwmon: (adt7475) set start bit in probe
The ADT7475 and ADT7476 have the STRT bit cleared by default[1]. Before any
monitoring activities the STRT bit needs to be set. Logically this needs
to happen before any of the sensors are read so the probe() function
seems the best place for it.

Joe Schaack bdaf9c40b2 hwmon: (ina209) Handled signed registers
The shunt voltage and current registers are signed 16-bit values so
handle them as such.

Javier Martinez Canillas a02c24a321 hwmon: (lm87) Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Javier Martinez Canillas 0439bf71c3 hwmon: (lm87) Remove unused I2C devices driver_data
The I2C device ID entries set a .driver_data but this data is never
looked up by the driver. So don't set it and also remove the enum.

Jaghathiswari Rankappagounder Natarajan 2d7a548a3e drivers: hwmon: Support for ASPEED PWM/Fan tach
The ASPEED AST2400/2500 PWM controller supports 8 PWM output ports.
The ASPEED AST2400/2500 Fan tach controller supports 16 tachometer
inputs.
The device driver matches on the device tree node. The configuration
values are read from the device tree and written to the respective
registers.
The driver provides a sysfs entries through which the user can
configure the duty-cycle value (ranging from 0 to 100 percent) and read
the fan tach rpm value.

Mahoda Ratnayaka 67043d1853 hwmon: (lm87) Allow channel data to be set from dts file
Currently there is no method for setting the channel
value from the DTS file. When, the driver uses a dts
file to initialize the driver platform_data is not set.
As a result channel variable may not be set correctly.

Without the channel variable set correctly, some of the
sensors will not be initialized correctly. For example
temp3 sensor sysfs entries.

This implements the schema agreed with the device tree
binding document.
