gpio-restart uses a priority of 128 and currently most soc-level restart mechanisms use the same - with some exceptions even using 192. But while the soc-level restarts are provided by the soc itself, gpio-restarts will most of the time be board-specfic and be used when some special board condition makes the soc-level restart only a second choice. The problem at hand manifested itself on the rk3288-veyron devices. While the soc-level restart can sucessfully restart all other rockchip boards I have, the veyron devices use an external restart mechanism that seems to not only reset the soc but also some external needed components. With both restart handlers having priority 128 in my tests the soc-specific variant took precedent in all cases. While it could restart the soc sucessfully in all cases, firmware then got an issue when talking to an external component, resulting in the device being put into recovery mode. So, give the board-specific restart handler a slight push and move it to priority 129 to make it more important than the generic soc-specific restart-handler.
