The Nuvoton NAU7802 ADC is able to adjust its gain but prior knowledge of its possible values was required to adjust it. Users had to guess the possible gain values based on the ADC datasheet or on this driver's code. This exposes the possible values in the in_voltage_scale_available file of each nau7802 ADC device. The gain is set for the whole ADC and is therefore not configurable by channel. Thus, there exists only one in_voltage_scale_available file for each nau7802 ADC device even if it has two separate channels. Signed-off-by:

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: https://lkml.org/lkml/2016/5/10/520 Signed-off-by:

This adds the following sysfs files according to the iio ABI: -rw-r--r-- 4096 in_accel_oversampling_ratio -r--r--r-- 4096 in_accel_oversampling_ratio_available Internally, the device knows about 4 different power modes that differ in oversampling ratio (and power consumption). We just show the user what oversampling ratio(s) is/are available, depending on the current frequency. The referenced table in the datasheets makes it easier to understand. Signed-off-by:

Currently the TIA gain settings are exported to userspace as sysfs entries that do not clearly represent their internal relation to the sampling stages. The gain settings are enabled on a per-stage basis, this can be seen in figure 24 of the current AFE4404 datasheet. These gain settings should therefore be tied to the channels that are read during these stages. Make this change here. Signed-off-by:

These AFEs have 4 ADC mesuring stages (called LED2, ALED2, LED1, and ALED1 in the datasheet), we map these as channels, these stages can serve different purposes depending on the application. For instance the AFE4404 has an additional LED (LED3), this LED can be timed to be active during stage 2 (or anystage, but the datasheet describes this case and the name of the stage reflects this use). This ability is used further in upcoming parts that tie the front-end gain and the LED timings together. For these reasons we remove explicit naming the channels. Without channel names it is best that the index numbers are in order to match the stage number, reorder the channel numbers. Signed-off-by:

The device has simple 8-bit registers but the driver incorrectly uses block or word reads without checking functionality bits. Fix by using i2c_smbus_read_i2c_block_data_or_emulated instead of i2c_smbus_read_i2c_block_data or i2c_smbus_read_word_data. This will check functionality bits and use the fastest available transfer method. Signed-off-by:

The hw_info array was indexed by enum inv_devices chip_type despite the fact that the enumeration had more members than the array and was ordered differently. The patch cleans this up and adds explicit chip_types to i2c/spi/acpi IDs. It also adds some stricter checks inside the driver core. This happened to work so far because the differences between the supported models are very minor. Signed-off-by:
