Hello nxp community,
I try to implement i2c-gpio on imx6ul via device-tree.
I already patch device-tree with the following lines and it compile nicely:
+#include <dt-bindings/gpio/gpio.h>
+/ {
+ i2c-device@0 {
+ compatible = "i2c-gpio";
+ sda-gpios = <&gpio1 9>;
+ scl-gpios = <&gpio1 1>;
+ i2c-gpio,sda-open-drain;
+ i2c-gpio,scl-open-drain;
+ i2c-gpio,delay-us = <120>;
+ };
+};
but i2c-gpio char device is missing in /dev/ folder when I boot up the target.
I also already compile kernel with i2c-gpio driver checked with menuconfig.
How I can access to i2c-gpio bus, or there is something missing in my devicetree patch ?
Thank you in advance for your advices.
Best Regards,
Luc
