This RTC appears in for example the Storlink Gemini family of SoCs.

- description: PCLK clocks
- description: EXTCLK clocks. Faraday calls it CLK1HZ and says the clock
should be 1 Hz, but implementers actually seem to choose different
clocks here, like Cortina who chose 32768 Hz (a typical low-power clock).
