Title: PCF8574 I2C-GPIO Expander driver [Print This Page] Author: KrunalShah Time: 5/11/2018 15:50 Title: PCF8574 I2C-GPIO Expander driver Hello,
I have added PCF8574 I2C-GPIO Expander in the rk3399-firefly-port.dtsi file but that driver is not getting loaded during the boot procedure.
I have checked the log messages but I did not find my driver. But apart from that .dtsi file, I did not do anything.
Am I missing anything to get that driver loaded?Author: tonywar618 Time: 1/12/2026 21:34
