hello ofer3,
you may update device tree to configure GPIO drive strength.
for example,
...
nvidia,pull-down-strength = <0xa>;
nvidia,pull-up-strength = <0xa>;
};
you may also refer to kernel documentation for property description.
for example,
- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest. The range of valid values depends on the pingroup. See "CAL_DRVDN" in the Tegra TRM.
- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest. The range of valid values depends on the pingroup. See "CAL_DRVUP" in the Tegra TRM.
