Subject: [PATCH v9 01/15] dt/bindings: Add bindings for GPT based FWU Metadata storage device
Date: Fri, 26 Aug 2022 15:27:02 +0530	[thread overview]
Message-ID: <20220826095716.1676150-2-sughosh.ganu@linaro.org> (raw)
In-Reply-To: <20220826095716.1676150-1-sughosh.ganu@linaro.org>

Add bindings needed for accessing the FWU metadata partitions. These
include the compatible string which point to the access method and the
actual device which stores the FWU metadata.

The current patch adds basic bindings needed for accessing the
metadata structure on GPT partitioned block devices.
