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.
