The same goes for the RTC in the JZ4780. Therefore, the ingenic,jz4770-rtc and ingenic,jz4780-rtc strings do not fall back anymore to ingenic,jz4760-rtc. The ingenic,jz4780-rtc string now falls back to the ingenic,jz4770-rtc string. Additionally, since the RTCs in the JZ4770 and JZ4780 support outputting the input oscillator's clock to the CLK32K pin, the RTC node is now also a clock provider on these SoCs, so a #clock-cells property is added.
