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.
