This patch set is one required step for Dove to hop into mach-mvebu. Until now, pinctrl-dove was hardcoding some registers that do not directly belong to MPP core registers. This is not compatible with what we want for mach-mvebu. This patch set removes all hardcoded addresses from pinctrl-dove by either requesting additional resources or requesting a syscon provided regmap for global config registers. As this changes existing driver to DT binding relationship, all additional resources are probed in a backward compatible way. If the corresponding resource cannot be found, we derive it from the existing pinctrl resource and warn about the old DTB firmware. Patch 1 and 2 add or update binding documentation for dove, global config syscon, and pinctrl-dove. The latter also documents missing reg property requirement for other mvebu pinctrl nodes. Patch 3 and 4 add the new pinctrl reg property values and global config register syscon to exisiting dove.dtsi. Patch 5 fixes a misdesign of common mvebu pinctrl driver, that requested the resource instead of getting it from the SoC specific driver stub. Patches 6 and 7 now add requests to the new resources in a backward compatible way, while patches 8-11 make use of those resources. At the end, there is no more hardcoded addresses in pinctrl-dove. The patch set is based on pre-v3.14-rc1 mainline. I suggest to take this in as v3.15 stuff. Since more Dove/mach-mvebu related patches will likely follow, Jason should prepare a topic branch for LinusW to pull from? It has been boot tested on Dove and compile tested only for Kirkwood, Armada 370 and XP.
