From ab1375e25ea3fef62a4a5a93abf5d03d67aaf99c Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 6 May 2026 00:52:43 +0800 Subject: [PATCH] arm64: dts: rockchip: Fix EEPROM compatible on rk3399-nanopi-r4s-enterprise The EEPROM used on the R4S (enterprise) is the 24AA025E48T-I/OT from MicroChip. This is a 2-Kbit EEPROM with 16-byte page size. The latter half of the EEPROM is read-only, and the last 48 bits contain a globally unique MAC address. That is to say this is not an ordinary EEPROM. The compatible for this type of EEPROM was introduced later that the board. Switch over to the correct compatible now that it is available.
