Subject: ARM: mvebu: armada-xp-openblocks-ax3-4: Disable internal RTC
|
|
Origin: https://git.kernel.org/linus/750e30d4076ae5e02ad13a376e96c95a2627742c
|
|
Bug-Debian: https://bugs.debian.org/784146
|
|
|
|
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"
|
|
|
