2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2017-01-28aspeed: Add basic ast2500-specific drivers and configurationmaxims@google.com
Clock Driver This driver is ast2500-specific and is not compatible with earlier versions of this chip. The differences are not that big, but they are in somewhat random places, so making it compatible with ast2400 is not worth the effort at the moment. SDRAM MC driver The driver is very ast2500-specific and is completely incompatible with previous versions of the chip. The memory controller is very poorly documented by Aspeed in the datasheet, with any mention of the whole range of registers missing. The initialization procedure has been basically taken from Aspeed SDK, where it is implemented in assembly. Here it is rewritten in C, with very limited understanding of what exactly it is doing.
