It's completely unrelated to FDT, it's a general issue.  There's no sane
way to use hacks like link ordering to resolve boot time dependencies -
start getting things like regulators connected to I2C or SPI controllers
which may also use GPIOs for some signals and may be parents for other
regulators and mapping out the dependency graph becomes unreasonably
complicated.  Deferred probing is designed to solve this problem by
working things out dynamically at runtime.
