Subject: [PATCH v3 07/10] mfd: da9063: Add custom IRQ map for DA9063L
Date:   Sat,  2 Jun 2018 12:11:52 +0200
Message-Id: <20180602101155.26375-7-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

While the datasheet for DA9063L (2v1, 23-Mar-2017) lists the RTC register
block, the DA9063L does not have an RTC. Add custom IRQ map for DA9063L to
ignore the Alarm and Tick IRQs from the PMIC.
