Hi, John

Checked from Hi6220 spec, and verified on HiKey:

+               rtc1: rtc@...04000 {
+                       compatible = "arm,pl031", "arm,primecell";
+                       reg = <0x0 0xf8004000 0x0 0x1000>;
+                       interrupts = <0 8 4>;
+                       clocks = <&ao_ctrl HI6220_RTC1_PCLK>;
+                       clock-names = "apb_pclk";
+               };
+

Would you please append that into the patch?
