+Subject: [PATCH] nvmem: imx-ocotp: Reverse MAC addresses on all i.MX derivates
+
+Not just i.MX8M, but all i.MX6/7 (and subtypes) need to reverse the
+MAC address read from fuses. Exceptions are i.MX6SLL and i.MX7ULP which
+do not support ethernet at all.
+
+Fixes: d0221a780cbc ("nvmem: imx-ocotp: add support for post processing")
