This was clarified by NXP during the discussion on this series [1] and the commit messages were not amended to take this new information into account, my fault. I would propose something like this here: ``` Add fsl,pps-channel property to select where to connect the PPS signal. This depends on the internal SoC routing and on the board, for example on the i.MX8 SoC it can be connected to an external pin (using channel 1) or to internal eDMA as DMA request (channel 0). ``` Francesco [1] https://lore.kernel.org/all/ZrPYOWA3FESx197L@lizhi-Precision-Tower-5810/
