Hi, The patchset presents alternative approach to superdevice DT node and components framework. It also refactors Exynos DRM device initialization. The first patch uses linker sections to get rid of ifdef macros, it is not essential for the rest of patchset but it makes code more readable. Similar approach is used by irqchip, clks and clk_sources. Any comments are welcome, especially regarding linker script usage in drivers. The second patch proposes pending_components framework - lightweight alternative for componentized devices. Details are described in the patch description. But as it is an alternative for component framework I would like to show differences: - it is simpler and more straightforward, - it requires only minimal changes to component drivers, - only one callback to implement, - no unwinding, component framework in case of error removes all already added components and unbinds all already bound components, - it is instantiated per superdevice, component framework uses global list, the disadvantage is that we create dependency between components and the superdevice, but in case of Exynos DRM the dependency is present already, - no two stage component initialization: probe, bind, - it is more lightweight, - it clearly separates device probing order issue from registering interfaces provided by the device. The third patch implements pending_components framework in Exynos DRM. Details are in patch description. The patchset is based on exynos-drm-next branch.
