+Subject: [PATCH] arm/dts: Correct Pi 4B LED values
+
+The initial PHY LED settings are wrong Pi 4B (the correct values got
+dropped somewhere along the way). The PHY declaration should arguably
+go in a separate file included by bcm2711-rpi-4-b.dts, but we can
+fix that as we switch over to using more of the upstream BCM2711
+support in 5.4 and later.
+
