tsl2x7x_read_thresh() and tsl2x7x_write_thresh() currently assumes that IIO_EV_INFO_VALUE is the only iio_event_info that will be passed in. This patch refactors these two functions so that additional iio_event_infos can be passed in. The functions are renamed from tsl2x7x_{read,write}_thresh() to tsl2x7x_{read,write}_event_value(). This patch also adds the missing return value check to tsl2x7x_invoke_change() since this was previously missing. This patch is in preparation for moving the in_intensity0_thresh_period and in_proximity0_thresh_period sysfs attributes to be created by iio_event_spec.

The calibration function calls i2c_smbus_write_byte() and i2c_smbus_read_byte(). These two function calls are replaced with a single call to i2c_smbus_read_byte_data() by this patch. This patch also removes an unnecessary call that reads the CNTRL register a second time. One of the error paths returned -1 if the ADC was not enabled and this patch changes that return value to -EINVAL. Signed-off-by:

tsl2x7x_i2c_read() would call i2c_smbus_write_byte() and i2c_smbus_read_byte(). These two i2c functions can be replaced with a single call to i2c_smbus_read_byte_data(). This patch removes the tsl2x7x_i2c_read() function and replaces all occurrences with a call to i2c_smbus_read_byte_data(). Signed-off-by:

Some part of the configuration are not touched after the probe and if something goes wrong on writing the initial one, the chip will misbehave. Adding an error checking ensures that the inital configuration will be written correctly. Moreover ensures that a sensible configuration will be saved in driver data and used subsequently as intended. Signed-off-by:

Added support for suspend/resume functionality for the ADC IP in sama5d2 SoC. In order to enter Suspend to ram mode (backup + self refresh mode for memory), in which the ADC IP is no longer powered, we need to reset the pins to default state, for the scenario when they are also used for I2C bus to communicate with the PMIC. On resume, we need to reconfigure the ADC IP registers and reconfigure the trigger registers in the case when the suspend procedure is done while sysfs has the buffer and trigger enabled. In the case the suspend happens exactly during a software triggered conversion, the request will time out, because we reset and power down the ADC. Signed-off-by:

Enable multiread by default for LIS3MDL since using I2C interface the subaddr Msb is used to automatically increase the slave address during multiple data read/write. In the same way, using SPI interface, bit 1 in register address is used to enable auto-increment of the slave address in multiple read/write.

The integration time is controlled by the ATIME register only. However, this register is written by i2c_smbus_write_word_data() in write_raw(). We actually don't need to write a subsequent register.
