bool to use sane defaults derived from the I2C specification when properties are not found, otherwise use 0
.RE
.SH "DESCRIPTION"
.PP
Scan the device for the generic I2C properties describing timing parameters for the signal and fill the given struct with the results\&. If a property was not found and use_defaults was true, then maximum timings are assumed which are derived from the I2C specification\&. If use_defaults is not used, the results will be 0, so drivers can apply their own defaults later\&. The latter is mainly intended for avoiding regressions of existing drivers which want to switch to this function\&. New drivers almost always should use the defaults\&.
