Most AXPxxx-based reference designs place a 10k NTC thermistor on a TS pin. axp20x IIO driver now report the voltage of this pin via additional IIO channel. Add new "ts_v" channel to the channel description. Signed-off-by:

Most AXPxxx-based reference designs place a 10k NTC thermistor on a TS pin. When appropriately configured, AXP PMICs will inject fixed current (80uA by default) into TS pin and measure the voltage across a thermistor. The PMIC itself will by default compare this voltage with predefined thresholds and disable battery charging whenever the battery is too hot or too cold. Alternatively, the TS pin can be configured as general-purpose ADC input. This mode is not supported by the driver. This patch allows reading the voltage on the TS pin. It can be then either processed by userspace or used by kernel consumer like hwmon ntc thermistor driver. Signed-off-by:

Enable/disable internal i2c controller slave autoprobing at bootstrap. Disable sensor-hub is useful if i2c controller clock/data lines are connected through a pull-up with other chip lines (e.g. SDO/SA0). Signed-off-by:

Introduce the capability to disable sensorhub through a device-tree property since there are some configurations where users want to explicitly disable sensor-hub auto-probing at bootstrap. A typical configuration is when the sensorhub clock/data lines are connected to a pull-up resistor since no slave sensors are connected to the i2c master. If SDO/SA0 line is connected to the same pull-up resistor, when the driver tries to probe slave devices connected on sensor-hub, it will force SDO/SA0 line to low, modifying the device i2c address.

The shared parameter should be configurable based on its usage, and not constrained to IIO_SHARED_BY_TYPE. This patch aims to improve the flexibility in using the IIO_ENUM_AVAILABLE define and avoid redefining custom iio enums that expose the shared parameter. An example is the ad5766.c driver where IIO_ENUM_AVAILABLE_SHARED was defined in order to achieve `shared` parameter customization. The current state of the IIO_ENUM_AVAILABLE implementation will imply similar redefinitions each time a driver will require access to the `shared` parameter. An example would be admv1013 driver which will require custom device attribute for the frequency translation modes: Quadrature I/Q mode and Intermediate Frequency mode. Signed-off-by:

Using `dev_get_drvdata()` in IIO sysfs callbacks to get a pointer to the IIO device is a relic from the very early days of IIO. The IIO core as well as most other drivers have switched over to using `dev_to_iio_dev()` instead. This driver is one of the last few drivers remaining that uses the outdated idiom, update it. This will allow to eventually update the IIO core to no longer set the drvdata for the IIO device and free it up for driver usage. Signed-off-by:

The at91-sama5d2 driver calls `to_platform_device()` on a struct device that is part of a IIO device. This is incorrect since `to_platform_device()` must only be called on a struct device that is part of a platform device. The code still works by accident because non of the struct platform_device specific fields are accessed. Refactor the code a bit so that it behaves identically, but does not use the incorrect cast. This avoids accidentally adding undefined behavior in the future by assuming the `struct platform_device` is actually valid. Signed-off-by:
