Subject: [PATCH v2 08/11] ASoC: cs42l42: Export regmap elements to core namespace
Date:   Thu, 15 Sep 2022 11:44:41 +0200
Message-Id: <20220915094444.11434-9-povik+lin@cutebit.org>
In-Reply-To: <20220915094444.11434-1-povik+lin@cutebit.org>
References: <20220915094444.11434-1-povik+lin@cutebit.org>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Export the regmap callbacks for indicating readable/volatile registers,
also the range structure, to the CS42L42 core namespace. This is in
advance of reusing these bits in a CS42L83 driver frontend.
