By using the info_mask_shared_by_all element of the channel spec, acce to the sampling frequency becomes available to in kernel users of the driver. It also shortens and simplifies the code.

The hardware, in those cases investigated supports it. It's just never been implemented.

However the right method is to use the compatible string. On detection, the ST sensors use the ID string to probe and instatiate the right sensor driver, so pass the kernel-internal ID string in the .data field of the OF match table, and set the I2C client name to this name when a compatible match is used. This avoids having misc Linux-specific strings floating around in the device tree.
