Subject: [PATCH v3 09/10] mfd: da9063: Handle less LDOs on DA9063L
Date:   Sat,  2 Jun 2018 12:11:54 +0200
Message-Id: <20180602101155.26375-9-marek.vasut+renesas@gmail.com>
In-Reply-To: <20180602101155.26375-1-marek.vasut+renesas@gmail.com>
References: <20180602101155.26375-1-marek.vasut+renesas@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Move the LDOs present only on DA9063 at the end of the list, so that
the DA9063L can simply indicate less LDOs and still share the list of
regulators with DA9063.
