Subject: arm64: dts: rockchip: add product-data eeproms to QNAP TS433
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=da6f4130234448122fe3e66c8116f7d9eea8a5c7;p=linux.git

arm64: dts: rockchip: add product-data eeproms to QNAP TS433

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.
