That seems extremely > We are talking about creating a dummy device because: - we need to give something for drm_platform_init(), - drm related data should be stored somewhere, - some data must be passed to all driver probe() functions. This is not hw-related data, but just some lists that are used to ensure that all drivers have been initialised before calling drm_platform_init(). All these issues are purely tegra-drm related and solving them elsewhere (in host1x) would be just wrong! host1x would not even use the dummy device for anything so creating it there seems bizarre. - Arto -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
