iio: humidity: hdc100x: add HDC1000 and HDC1008 to Kconfig

2016-08-15T16:10:56+00:00

hdc100x supports Texas Instruments HDC1000 and HDC1008 relative
humidity and temperature sensors. Add these product names to
Kconfig.

iio: humidity: hdc100x: fix sensor data reads of temp and humidity

2016-08-15T16:01:53+00:00

Replace the i2c_smbus_read_byte commmands used to retrieve the sensor
data with an i2c_master_recv command.

The smbus read byte method fails because the device does not expect a
stop condition after sending the first byte. When we issue the second
read, we are getting the first byte again. Net effect is that of the 14
bits used for the measurement, the 8 most significant bits are correct,
the lower 6 are not.

None of the smbus read protocols follow the pattern this device requires
(S Addr Rd [A] Data [A] Data NA P), hence the switch to an i2c receive
transaction.

Applicable from original introduction of this driver, but will require
backporting due to churn in the code.

iio: add Kconfig selects needed for triggered buffer compiles

2016-08-15T14:42:04+00:00

Select IIO_BUFFER and IIO_TRIGGERED_BUFFER to compile.
Remove IIO_TRIGGER if present since IIO_BUFFER selects it.

iio: humidity: am2315: set up buffer timestamps for non-zero values

2016-08-15T14:39:23+00:00

Use the iio_pollfunc_store_time parameter during triggered buffer
set-up to get valid timestamps.

iio: hudmidity: hdc100x: fix incorrect shifting and scaling

2016-06-03T12:25:33+00:00

Shifting sensor data to the right 2 bits was incorrect and caused the
scaling values + offsets to be invalid.

iio: humidity: hdc100x: fix IIO_TEMP channel reporting

2016-05-29T18:45:54+00:00

IIO_TEMP channel was being incorrectly reported back as Celsius when it
should have been milliCelsius. This is via an incorrect scale value being
returned to userspace.

iio: Export I2C module alias information

2016-05-21T19:08:14+00:00

The I2C drivers have an i2c_device_id array but that information isn't
exported to the modules using the MODULE_DEVICE_TABLE() macro. So the
modules autoloading won't work if the I2C device is registered using
OF or legacy board files due missing alias information in the modules.

The issue was found using Kieran Bingham's coccinelle semantic patch:

We haven't taken the lock yet so we don't need to unlock here.
