Subject: [PATCH 3/5] nvmem: meson-efuse: bindings: Add secure-monitor phandle
Date: Mon, 29 Jul 2019 19:39:39 +0100 [thread overview]
Message-ID: <20190729183941.18164-4-ccaione@baylibre.com> (raw)
In-Reply-To: <20190729183941.18164-1-ccaione@baylibre.com>
Add a new property to link the nvmem driver to the secure-monitor. The
nvmem driver needs to access the secure-monitor to be able to access the
fuses.
