 ### Overlay details:
 
+### mksklipad-enable-rtc-end1
+
+Enables end1 ethernet adapter, which also makes rtc work better.
+There is no physical port for end1, so this overlay is merely for
+testing the rtc.
+The rtc still tends to stall sometimes. In the original makerbase
+image, the rtc was completely unusable though.
+
 ### mkspi-disable-lcd-spi
 
 DTBO to disable spi_for_{lcd,touch} when enabling uart1
