[PATCH v2 37/37] ARM: tegra: colibri_t20: add eval board device tree

Marcel Ziswiler
2018-09-02T10:10:36Z

Add an evaluation board device tree more in-line with all our other
device trees.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

---

Changes in v2:
- Updated evaluation board device tree with all applicable previous
fixes.
- Also reflect this addition in the device tree bindings documentation.
