Thanks for the inputs, similar data but not exact is added to
v5 series.
+ gpio-leds {
+ compatible = "gpio-leds";
+ pinctrl-names = "default";
+ pinctrl-0 = <&userled_pins>;
+
+ led0 {
+ label = "status:green:user0";
+ gpios = <&gpio2 21 0>;
+ default-state = "off";
+ };
+
+ led1 {
+ label = "status:green:user1";
+ gpios = <&gpio2 22 0>;
+ default-state = "off";
+ };
+
+ led2 {
+ label = "status:green:user2";
+ gpios = <&gpio2 23 0>;
+ default-state = "off";
+ };
+
+ led3 {
+ label = "status:green:user3";
+ gpios = <&gpio2 24 0>;
+ default-state = "off";
+ };
+ };
+
Can you review my v5 patches and tell me if there are any
modifications/changes required?
Thanks
