[PATCH] Documentation: dt: Add binding for /chosen/secure-stdout-path
From: Jerome Forissier <hidden>

Subsystem:
open firmware and flattened device tree bindings, the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Some platforms may use a single device tree to describe two address
spaces, as described in d9f43babb998 ("Documentation: dt: Add bindings
for Secure-only devices"). We extend the use of the secure- prefix to
the stdout-path property, so that the Secure firmware may use a
different console device than the one used by the kernel.
