This patchset brings a series of improvements for the Actions Semi S500
SoCs family, by adding support for Clock & Reset Management Units, DMA,
MMC & I2C controllers.

Please note the patches contain only DTS changes, but most of them
depend on previous work which is currently under review:

 - Add RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs

 - Add Actions Semi S500 pinctrl support

For the moment, I have only enabled the features tested on RoseapplePi,
the SBC for which an initial support has been already submitted via:
