[namiltd]

• Rename the mt7621_dlink_dir-xx60-a1.dtsi file to a more appropriate name.
• Abandoning the label and using the function/color syntax for some dlink dir series routers: dir-1960-a1, dir-2660-a1, dir-2640-a1, dir-3040-a1 and dir-3060-a1
• Setting the LED name and abandoning the label and using the function/color syntax for some TP-Link Archer series routers: Archer C2 v1, Archer C20 v1, Archer C20i and Archer C50 v1

ok cool I guess with v24 if you sysupgrade you have to fix the leds with the version change I think you have to change the aliases as well tho

	aliases {
		label-mac-device = &gmac0;
		led-boot = &led_power_orange;
		led-failsafe = &led_power_white;
		led-running = &led_power_white;
		led-upgrade = &led_net_orange;
	};

These names have not changed, so they can remain. As for sysupgrade, you are right.
