With this change the backlight LED string and the keypad
LED strings will be controlled separately.

Since I'll be creating integration branch for this series,
and it would be good to have this patch in it too, then
I can do the amendments by myself:
+ lcd_backlight: led@0 {
+ reg = <0>;
+ led-sources = <2>;
+ ti,led-mode = <0>;
+ label = "backlight";
s/backlight/:backlight/
+ linux,default-trigger = "backlight";
+ };
+
+ led@1 {
+ reg = <1>;
+ led-sources = <1>;
+ ti,led-mode = <0>;
+ label = "platform::kbd_backlight";
s/platform::kbd_backlight/:kbd_backlight/
and then send you a pull request.
Would you be OK with that?
};
};
};
