12 depends on OF_IRQ && OF_EARLY_FLATTREE
15 This option builds in test cases for the device tree infrastructure
16 that are executed once at boot time, and the results dumped to the

39 On some platforms, the device tree can be manipulated at runtime.
40 While this option is selected automatically on such platforms, you
41 can enable it manually to improve device tree unit test coverage.
