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. + +Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> +--- + arch/arm/boot/dts/armada-385-linksys.dtsi | 5 +++++ + 1 file changed, 5 insertions(+) + +--- a/arch/arm/boot/dts/armada-385-linksys.dtsi ++++ b/arch/arm/boot/dts/armada-385-linksys.dtsi +@@ -302,3 +302,8 @@ + status = "okay"; + usb-phy = <&usb3_1_phy>; + }; ++ ++&rtc { ++ /* No crystal connected to the internal RTC */ ++ status = "disabled"; ++}; |
