Subject: [PATCH v6 0/4] iio: humidity: Add driver for ti HDC302x humidity sensors

Add support for HDC302x integrated capacitive based relative
humidity (RH) and temperature sensor.
This driver supports reading values, reading the maximum and
minimum of values and controlling the integrated heater of
the sensor.

changes in v6:
	sensor driver:
	  - Drop offset for humidity channel.
	  - Use put_unaligned_be16 to assign the 14-bit heater value.
	  - Remove error message if devm_action_or_reset() fails.
	  - Add eror message if devm_iio_device_register() fails.
	dt-bindings:
	  - remove items before "- const: ti,hdc3020".
	  - add vdd-supply to required.
changes in v5:
	iio ABI:
	  - Document _TROUGH as an info element.
	sensor driver:
	  - Correct heater enable/disable commands
	  - Rearrang header files in alphabetical order.
	  - Change .info_mask_separate to BIT(IIO_CHAN_INFO_RAW). 
	  - Add details to mutex comment.
	  - Add error handling for chan->type in read_raw call.
	  - Remove error message for devm_iio_device_register.
changes in v4:
	iio core:
	  - Add an IIO_CHAN_INFO_TROUGH modifier for minimum values.
	iio ABI:
	  - Document the new _TROUGH modifier.
	sensor driver:
	  - Add MAINTAINERS.
	  - Use new IIO_CHAN_INFO_TROUGH modifier.
	  - Support the complete heater range.
	  - Remove measurement values from the data structure.
	  - Use guard(mutex)(...), make the code simpler
	  - Removed buffer mode and direct mode conversion code
	  - Minor coding-style fixes.
	dt-bindings:
	  - removed unnecessary example
	  - add vdd-supply to the example
changes in v3:
	sensor driver:
	  - Removed the custom ABI
	  - Give up calculating values in the driver
	  - Use read_avail callback to get available parameters
	  - Changed the scope of the lock to make the code more concise
	  - Fixed the code format issue
	dt-bindings:
	  - Use a fallback compatible
changes in v2:
	sensor driver:
	  - Added static modification to global variables
	  - change the methord to read peak value
	dt-bindings:
	  - change the maintainers to me.
	  - hdc3020,hdc3021,hdc3022 are compatible,I've changed the dirver.
	  - change the node name to humidity-sensor.
