ARM: mvebu: armada-xp-openblocks-ax3-4: Disable internal RTC
commit 750e30d4076ae5e02ad13a376e96c95a2627742c upstream. There is no crystal connected to the internal RTC on the Open Block AX3. So let's disable it in order to prevent the kernel probing the driver uselessly. Eventually this patches removes the following warning message from the boot log: "rtc-mv d0010300.rtc: internal RTC not ticking" Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
