[PATCH 00/11] Add CMU/RMU/DMA support for Actions Semi S500 SoCs

> 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/
> 
> 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.
