From 18d0f98a17757c4030c0af046dfd864c8108738a Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sat, 20 Sep 2025 12:56:51 +0100 Subject: [PATCH] arm64: dts: mediatek: mt7986a: add 'soc-uuid' cell to efuse The efuse of the MediaTek MT7986 contains an 8-byte unique identifier. Add a 'soc-uuid' cell covering those 8 bytes to the nvmem defininition of the efuse to allow easy access from userspace, eg. to generate a persistent random MAC address on boards like the BananaPi R3 which doesn't have any factory-assigned addresses.
