NAME
       i2c_parse_fw_timings - get I2C related timing parameters from firmware

SYNOPSIS
       void i2c_parse_fw_timings(struct device * dev, struct i2c_timings * t, bool use_defaults);

ARGUMENTS
       dev
           The device to scan for I2C timing properties

       t
           the i2c_timings struct to be filled with values

       use_defaults
           bool to use sane defaults derived from the I2C specification when properties are not
           found, otherwise use 0

DESCRIPTION
       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.
