Subject: Re: [PATCH v8 06/11] rtc: sun6i: Add support for RTCs without external LOSCs

Hi Andre!

Dne petek, 23. julij 2021 ob 17:38:33 CEST je Andre Przywara napisal(a):
> Some newer Allwinner RTCs (for instance the one in the H616 SoC) lack
> a pin for an external 32768 Hz oscillator. As a consequence, this LOSC
> can't be selected as the RTC clock source, and we must rely on the
> internal RC oscillator.
> To allow additions of clocks to the RTC node, add a feature bit to ignore
> any provided clocks for now (the current code would think this is the
> external LOSC). Later DTs and code can then for instance add the PLL
> based clock input, and older kernel won't get confused.
