| Subject: ARM: mvebu: armada-xp-openblocks-ax3-4: Disable internal RTC |
| |
| From: Gregory CLEMENT <gregory.clement@free-electrons.com> |
| |
| 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" |
