Using LibIIO to read/write registers BUT device does NOT have debug attr: direct_reg_access

[zambezie14]

I would like to read/write device registers on a sensor. I am able to use iio_device_reg_write() and iio_device_reg_read() if the device has the debug attr: direct_reg_access; however, this device does not have this. What is the recommended best practice for reading and writing registers where this debug attr is not included? Thank you in advance.

Well, in case the driver doesn't expose this attribute in debugfs, there is not way to access registers.
