[PATCH 04/15] dt-bindings: rtc: sun6i-rtc: Export internal RC oscillator
From: Chen-Yu Tsai <hidden>
Date: 2018-11-28 09:32:15
Also in:

Subsystem:
open firmware and flattened device tree bindings, real time clock (rtc) subsystem, the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Alexandre Belloni, Linus Torvalds
Experiments showed that on at least the H3/H5/A64 the RTC's internal oscillator also feeds the CPUS mux in the PRCM. Export this clock through the device tree, instead of having to use a dummy fixed-clock device node, for the PRCM to consume. This will properly describe the relationship between the clocks.
