Subject: [RFC PATCH v1 2/2] doc: device-tree-bindings: optee: support rpmb-dev property
Date: Sun, 24 Jan 2021 11:23:04 +0200 [thread overview]
Message-ID: <20210124092304.51462-2-igor.opaniuk@gmail.com> (raw)
In-Reply-To: <20210124092304.51462-1-igor.opaniuk@gmail.com>
From: Igor Opaniuk <igor.opaniuk@foundries.io>
Add support for "rpmb-dev" property which provides eMMC phandle
for RPMB-related operations.
This commit is created only to show DT node updates for RFC patch,
obviously that node should be updated in device-tree-bindings in
Linux first, that pulled here.
