Yeah, that was my guess - either an out of spec voltage/frequency was selected or the regulator isn't able to keep up with the voltage transition or a load spike and the power browns out.

I guess this is related to arm64: dts: rockchip: correct voltage selector Firefly-RK3399 [0] which is in so far interesting as the patch seems to fix a similar issue to the above with the opposite "fcs,suspend-voltage-selector" value. And also claims to be in line with the vendor kernel. >From looking at the schematics, we might have a discrepancy between the fcs,suspend-voltage-selector and vsel input-pin leading to a gpio [likely depending on what the bootloader set this pin up for]. I'll drop the patch for now and get in contact with the patch submitter. Heiko [0] https://patchwork.kernel.org/patch/10447075/ ^ permalink raw reply [flat|nested] 4+ messages in thread
