[PATCH 2/4] arm64: tegra: Add ID EEPROM for Jetson TX2 Developer Kit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Thierry Reding <treding@xxxxxxxxxx>

There is an ID EEPROM on the Jetson TX2 carrier board, part of the
Jetson TX2 Developer Kit, that exposes information that can be used to
identify the carrier board. Add the device tree node so that operating
systems can access this EEPROM.
