So I've tried the patch on the pinephone and it doesn't work. I suspect you need to at least enable a led driver like LED_GPIO but even when I do that, while I can make the led turn on/off manually, it doesn't come on in early boot like it does with the old code. There's definitely something else missing here. Peter
