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

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

[Cristian Ciocaltea]

Hi,

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.

Thanks,
Cristi

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

[PATCH v2 05/18] dmaengine: owl: Add compatible for the Actions Semi S500 DMA controller

[Cristian Ciocaltea]

The DMA controller present on the Actions Semi S500 SoC is compatible
with the S900 variant, so add it to the list of devices supported by
the Actions Semi Owl DMA driver.

I hope that you have verified both Memcpy and Slave transfers...

I have been using 'dmatest' module as documented in:
https://www.kernel.org/doc/html/latest/driver-api/dmaengine/dmatest.html

I tested all the available channels and could not find any signs of
possible issues. Bellow is an excerpt from the kernel ring buffer:

[ 2661.888448] dmatest: dma0chan3-copy0: summary 300 tests, 0 failures 1730.62 iops 13648 KB/s (0)

Should I perform some additional tests?

Nope, this is sufficient. Since you have tested slave transfer with MMC driver,
running dmatest for memcpy is fine.
