Platform implementations of dw-mshc controller may choose to extend the features of the standard dw-mshc controller such as adding additional clocking options or modifying the bus interface. Support for such implementation specific extensions can be incorporated into dw_mmc-pltfm, but including multiple such platform specific implementations would convolute the existing dw_mmc-pltfm code. Instead, it would be better to create implementation specific platform drivers to support implementation specific features. Such platforms drivers can reuse the existing infrastructure in dw_mmc-pltfm for resource identification and controller registration and provide support for implementation specific features. So, allow the infrastructure in dw_mmc-pltfm to be reused by other implementation specific platform drivers.
