+Subject: [PATCH] overlays: Fix compatible string for ds1307 RTC
+
+Kernels since 4.19 have required the correct manufacture name in the
+compatible string for I2C devices, and unfortunately the one for the
+Dallas/Maxim DS1307 should have been "dallas,ds1307" and not
+"maxim,ds1307".
+
+See: https://github.com/raspberrypi/linux/issues/3013
