[PATCH v3] ARM: dts: aspeed: anacapa: Add retimer EEPROMs
From: Dirk Chen via B4 Relay
Date: Thu Feb 19 2026 - 10:45:10 EST
From: Dirk Chen <dirkchen@xxxxxxx>
The Anacapa board features Atmel 24C2048 EEPROMs on i2c0 and i2c1, which
are used to store retimer configurations. Add the corresponding device
tree nodes to support these components.
Signed-off-by: Dirk Chen <dirkchen@xxxxxxx>

Changes in v3:
- Reorder I2C device nodes by ascending address (place eeprom@50
before i2c-mux@70)
- Link to v2: https://lore.kernel.org/r/20260209-b4-anacapa-dts-fix-v2-1-fe446a7038bf@xxxxxxx
Changes in v2:
- Improved commit description to clarify that the change reflects
actual hardware as requested by the reviewer.
- Removed mentions of other platforms to avoid confusion.
- Link to v1: https://lore.kernel.org/r/20260202-b4-anacapa-dts-fix-v1-1-20d4b0114854@xxxxxxx
