Subject: [PATCH v6 1/9] dt-bindings: mfd: Add TI-Nspire misc registers
Date: Wed, 8 Mar 2023 10:55:48 -0600 [thread overview]
Message-ID: <20230308165557.2242-2-afd@ti.com> (raw)
In-Reply-To: <20230308165557.2242-1-afd@ti.com>
The TI Nspire devices contain a set of registers with a seemingly
miscellaneous set of functionality. This area is known simply as the
"misc" region.
