Subject: [PATCH v4 05/12] ARM: dts: aspeed: anacapa: Add additional EEPROM node for SCM
Date: Wed, 05 Aug 2026 21:02:33 +0800 [thread overview]
Message-ID: <20260805-anacapa-devlop-phase-devicetree-v4-5-5d67e0efa6c5@gmail.com> (raw)
In-Reply-To: <20260805-anacapa-devlop-phase-devicetree-v4-0-5d67e0efa6c5@gmail.com>
From: Colin Huang <u8813345@gmail.com>
The SCM FRU EEPROM I2C address differs between SCM revisions:
- Rev B uses address 0x50
- Rev C/D/E/F and later use address 0x51
Add an additional AT24C128 EEPROM node at 0x51 on i2c9 so the same
device tree can support multiple SCM revisions.
