Robin Murphy	f99e689181	gpu: host1x: Register context bus unconditionally ... Conditional registration is a problem for other subsystems which may unwittingly try to interact with host1x_context_device_bus_type in an uninitialised state on non-Tegra platforms. A look under /sys/bus on a typical system already reveals plenty of entries from enabled but otherwise irrelevant configs, so lets keep things simple and register our context bus unconditionally too.

Mikko Perttunen	597b89d30b	gpu: host1x: Add context bus ... The context bus is a "dummy" bus that contains struct devices that correspond to IOMMU contexts assigned through Host1x to processes. Even when host1x itself is built as a module, the bus is registered in built-in code so that the built-in ARM SMMU driver is able to reference it.
