This patch set fixes clk init order that went upside-down with v3.14. I haven't really investigated what caused this, but I assume it is related with DT node reordering by addresses.
Anyway, with v3.14 for MVEBU SoCs, the clock gating driver gets registered before core clocks driver. Unfortunately, we cannot return -EPROBE_DEFER in drivers initialized by clk_of_init. As the init order for our drivers is always core clocks before clock gating, we maintain init order ourselves by hooking CLK_OF_DECLARE to one init function that will register core clocks before clock gating driver.
This patch is based on pre-v3.14-rc1 mainline and should go in as fixes for it. As we now send MVEBU clk pull-requests to Mike directly, I suggest Jason picks it up as a topic branch.
The patches have been boot tested on Dove and compile-tested only for Kirkwood, Armada 370 and XP.
