arm64: dts: rockchip: add product-data eeproms to QNAP
From: Heiko Stuebner <heiko@...> Date: Sun, 4 Aug 2024 16:06:21 +0200
Commit-Message
The device contains two i2c-connected eeproms holding some product- specific values. One sitting on the mainboard and one on the statically connected backplane. While the eeprom chips themself have a size of 512 byte, the eeprom data only uses 256 byte each, probably to stay compatible with other models. Signed-off-by: Heiko Stuebner <heiko@...>
