+Subject: [PATCH] overlays: balenaFin v1.1.0 carrier board update
+
+A backward compatible update for the balenaFin carrier board for the
+Raspberry Pi Compute Module 3/3+ Lite.
+
+The updated overlay includes:
+ * support for the newly introduced RGB LEDs
+ * i2c-gpio and SDIO improvements
+ * DT based Marvell 88W8887 configuration
