Subject: [PATCH v6 12/14] mfd: da9063: Register RTC only on DA9063L
Date:   Mon, 11 Jun 2018 13:58:49 +0200
Message-Id: <20180611115851.1987-12-marek.vasut+renesas@gmail.com>
In-Reply-To: <20180611115851.1987-1-marek.vasut+renesas@gmail.com>
References: <20180611115851.1987-1-marek.vasut+renesas@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The DA9063L does not contain RTC block, unlike the full DA9063.
Split the RTC block into separate mfd cell and register it only
on DA9063.

V2: No change
V3: Rework of mfd: da9063: Disallow RTC on DA9063L
V4: - Change the original failure text
    - Use PLATFORM_DEVID_NONE in mfd_add_devices
V5: Rebase on top of new 01 and 02 patches
V6: No change
