This patch series improves the existing implementation of the Clock
Management Unit for the Actions Semi S500 SoC, by adding support for
some missing clocks, like DMAC and GPIO.

Additionally, it enables the UART nodes in the common owl-s500 DTS to
use the clock provided by the CMU. That means the S500 based SBCs can
now get rid of their (fake) UART fixed clock and, as a matter of fact,
this has been already done here for RoseapplePi, the new board which
is going to be supported (hopefully) via the following patchset:
https://lore.kernel.org/lkml/cover.1592123160.git.cristian.ciocaltea@gmail.com/ (local)

Eventually, the patchset adds support for the Actions Semi S500 SoC's
DMA controller and Reset Management Unit. Please note the already
existing Actions Semi Owl SoCs DMA driver seems to be fully compatible
with S500, even though this is not explicitly mentioned in the source
code. For the moment, I have just enabled the DMA controller node in
owl-s500 DTS using the "actions,s900-dma" compatible string.

In the upcoming patch series I will provide a pinctrl driver and enable
access to MMC and I2C.

Can you please untangle this from the DTS changes? The clk driver
changes will go through the clk tree and the DTS changes will go through
arm-soc. Please send them as separate patch series to the respective
maintainers.

Hi Stephen,

Thank you for reviewing!
I will submit v2 having the DTS related changes removed from this patch
series.

Regards,
Cristi
