- Subject: ARM: dts: armada-385-linksys: Disable internal RTC
- The internal RTC does not work correctly on these Linksys boards based
- on Marvell SoCs. For me it only shows Wed Dec 31 23:59:59 1969 and for
- others it is off by 3 minutes in 10 minutes running, this was reported
- by multiple users. On the Linksys Mamba device the device tree comment
- says that no crystal is connected to the internal RTC, this is probably
- also true for the other devices.
