Hi, this is version 2 of a series that probes devices in dependency order so as to avoid deferred probes. While deferred probing is a powerful solution that makes sure that you eventually get a working system at the end of the boot, can make it very time consuming to find out why a device didn't probe and can also introduce big delays in when a device actually probes by sending it to the end of the deferred queue. So far I have only tested on a Tegra124 Chromebook. Thanks, Tomeu Changes in v2: - Instead of delaying all probes until late_initcall, only delay matches of platform devices that have a firmware node attached. - Allow bindings implementations register a function instead of using class callbacks, as not only subsystems implement firmware bindings. - Move strends to string.h - Document that consumers of backlight devices can use the 'backlight' property to hold a phandle to the backlight device. - Allocate the list of dependencies and pass it to the function that fills it.
