[PATCH v2 00/18] Add CMU/RMU/DMA/MMC/I2C support for Actions Semi S500 SoCs

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 & SIRQ controllers.

Please note the patches consist mostly of DTS and bindings/compatibles
changes, since all the work they depend on has been already merged,
i.e. clock fixes/additions, pinctrl driver, sirq driver.

For the moment, I have only enabled the features I could test on
RoseapplePi SBC.


Changes in v2:
- Added new bindings/compatibles for S500 DMA, MMC & I2C controllers
- Added support for the SIRQ controller
- Added new entries in MAINTAINERS
- Updated naming of some patches in v1
