X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8300a70e6567d2b89791708bc618c506ef29262d;p=linux.git

arm64: tegra: Add ID EEPROMs on Jetson Nano

The Jetson Nano has two ID EEPROMs, one for the module and another for
the carrier board. Add both to the device tree so that they can be read
from at runtime.
