Subject: [PATCH v2 1/4] dt-bindings: dma: ti: k3-*: Add descriptions for register regions
Date: Wed, 22 Nov 2023 21:12:35 +0530 [thread overview]
Message-ID: <20231122154238.815781-2-vigneshr@ti.com> (raw)
In-Reply-To: <20231122154238.815781-1-vigneshr@ti.com>
In preparation for introducing more register regions, add description
for existing register regions so that its easier to map reg-names to
that of SoC Documentations/TRMs.
