This series hooks up the watchdog uclass to automatically register the first watchdog device for use with sysreset, doing a bit of minor cleanup along the way.
The goal is for this to replace the sunxi board-level non-DM reset_cpu() function. I was surprised to find that the wdt_reboot driver requires its own undocumented device tree node, which references the watchdog device by phandle. This is problematic for us, because sunxi-u-boot.dtsi file covers 20 different SoCs with varying watchdog node phandle names. So it would have required adding a -u-boot.dtsi file for each board.
Hooking things up automatically makes sense to me; this is what Linux does. (In fact, Linux does this for every watchdog device.) However, I put the code behind a new option to avoid surprises for other platforms.
