[PATCH v2 0/4] Add initial support for RoseapplePi SBC

[PATCH v2 0/4] Add initial support for RoseapplePi SBC

[Cristian Ciocaltea]

This patchset enables basic support for RoseapplePi, relying exclusively
on the existing infrastructure for the Actions Semi Owl SoCs (thanks to
Andreas and Mani for making this possible).

The SBC is powered by the Actions Semi S500 SoC and comes with 2GB RAM,
uSD slot and optional eMMC storage. For more details, please check:
http://roseapplepi.org/index.php/spec/

The upcoming patches will improve this initial support by adding the
missing bits and pieces to the S500 clock management unit, which is a
prerequisite for providing an S500 pinctrl and gpio driver, in order to
eventually enable access to additional functionality like I2C and MMC.

Thanks and regards,
Cristian Ciocaltea

Changes in v2:
 - Added Reviewed-by and Acked-by tags from Rob

Rob, are you going to take this patch? Else I'll take this through arm-soc tree!
