Subject: [PATCH] ARM: tegra: add device tree for Tegra Note 7
Date: Mon, 3 Mar 2014 12:50:16 +0900 [thread overview]
Message-ID: <1393818616-27131-1-git-send-email-acourbot@nvidia.com> (raw)
Add a device tree for Tegra Note 7. The set of enabled features is
still minimal with no display option and USB requiring external power.
Pinctrl is not set yet, as the bootloader-provided values allow us to
use the currently-supported hardware.
A default kernel command-line as well as initrd addresses are hardcoded
to match the static values the bootloader is known to use. This allows
booting from an appended DTB without having to alter it at boot time,
since the bootloader has no Device Tree support.
