Iain Paton 27f8b13555 hwmon: Honeywell Humidicon HIH-6130/HIH-6131 humidity and temperature sensor driver
This is a new driver for the Honeywell Humidicon HIH-6130/HIH-6131 humidity sensor.

The driver is based on the existing Sensiron sht21 driver with the necessary changes
to the probe, update_measurements and conversion functions necessary to use the
Honeywell sensors.

There's no difference between the 6130 & 6131 other than the 6131 having an external
condensation filter attached.

Description
-----------
The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package.
The difference between the two devices is that the HIH-6131 has a condensation
filter.
The devices communicate with the I2C protocol. All sensors are set to the same
I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27)
can be used in the board setup code.
Please see Documentation/i2c/instantiating-devices for details on how to
instantiate I2C devices.
