2022-09-21iio: proximity: srf04: Use pm_ptr() to remove unused struct dev_pm_opsJonathan Cameron
If CONFIG_PM is not set, the pm_ptr() will ensure that the struct dev_pm_ops and callbacks are removed without the need for __maybe_unused markings. In this case we can't simply use DEFINE_RUNTIME_DEV_PM_OPS() because that would provide suspend and resume functions without the checks the driver is doing before calling runtime_pm functions (whether the necessary GPIO is provided). It may be possible to clean that up in future by moving the checks into the callbacks.

2022-09-21iio: imu: add Bosch Sensortec BNO055 core driverAndrea Merello
Add the core driver for the BNO055 IMU from Bosch. This IMU can be connected via both serial and I2C busses; separate patches will add support for them. The driver supports "AMG" (Accelerometer, Magnetometer, Gyroscope) mode, that provides raw data from the said internal sensors, and a couple of "fusion" modes (i.e. the IMU also does calculations in order to provide euler angles, quaternions, linear acceleration and gravity measurements). In fusion modes the AMG data is still available (with some calibration refinements done by the IMU), but certain settings such as low pass filters cut-off frequency and sensors' ranges are fixed, while in AMG mode they can be customized; this is why AMG mode can still be interesting.

2022-09-21iio: add support for binary attributesAndrea Merello
When a IIO device is registered, the IIO core creates an attribute group on its own, where it puts the channel attributes, and where it copies the attributes in indio_dev->info->attrs. Unfortunately it doesn't take care of binary attributes (i.e. it only consider indio_dev->info->attrs->attrs, and it ignores indio_dev->info->attrs->bin_attrs). Fix this by making the IIO layer take care also of the binary attributes. Note that while it is necessary to copy the non-binary attributes because the IIO layer needs more room to add the channels attribute, it should be enough to assign the bin_attrs pointer to the binary attributes pointed by indio_dev->info->attrs->bin_attrs.

Set the iio device's name based on the chip used for the LTC2499 only. The most common way for IIO clients to interact with a device is to address it based on it's name. By using the dev_name() function, the name will be set based on a i2c_client's kobj name, which has the format i2c_instance-i2c_address (1-0076 for example). This is not ideal, since it makes a requirement for userspace to have knowledge about the hardware connections of the device. The name field is set to NULL for the LTC2497 and LTC2496, so that the old name can kept as it is, since changing it will result in an ABI breakage.

2022-09-21iio: dac: ad5593r: Fix i2c read protocol requirementsMichael Hennerich
For reliable operation across the full range of supported interface rates, the AD5593R needs a STOP condition between address write, and data read (like show in the datasheet Figure 40) so in turn i2c_smbus_read_word_swapped cannot be used. While at it, a simple helper was added to make the code simpler.
