[PATCH 2/2] arm64: dts: rockchip: add product-data eeproms to QNAP TS433

[Heiko Stuebner]

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.
