[0/4] Add initial support for RoseapplePi SBC

This patchset enables basic support for RoseapplePi, relying exclusively
on the existing infrastructure for the Actions Semi Sxx SoCs (thank you
Andreas and Manni 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

On a related note: There is now an owl-mmc driver for the s900. From a
quick look at the datasheet it looks compatible with the controller on
the s500. Did you have a look at hooking that up?

Yes, please see:

The clock related patches have been already applied to v5.9 and
hopefully the pinctrl driver will follow in v5.10.
