The thing is, you're not lerading the DTS only but the whole kernel programming. This is a huge codebase, so yes, there are some shortcuts, but the road is still very long. > I'm seeing a lot of references to: > > #include <linux/of.h> > > #include <linux/of_device.h> > #include <linux/of_platform.h> > > Are these "of.." headers specific to device tree? Yes. OpenFirmware was one of the DT, the Flattened Device Tree being another. You'll find mention of OF, FDT and DT in the kernel on numerous places in the kernel.
