Chen-Yu Tsai 04940631b8 rtc: ac100: Add clk output support
The AC100's RTC side has 3 clock outputs on external pins, which can
provide a clock signal to the SoC or other modules, such as WiFi or
GSM modules.

Support this with a custom clk driver integrated with the rtc driver.

Chen-Yu Tsai d00a18a42c rtc: ac100: Add RTC driver for X-Powers AC100
X-Powers AC100 is a codec / RTC combo chip. This driver supports
the RTC sub-device.

The RTC block also has clock outputs and non-volatile storage.
Non-volatile storage wthin the RTC hardware is not supported.
