[PATCH v3 00/13] Add CMU/RMU/DMA/MMC/I2C support for Actions Semi

[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 v3:
- Squashed 'arm: dts: owl-s500-roseapplepi: Use UART clock from CMU' with
  'arm: dts: owl-s500: Set CMU clocks for UARTs', according to Mani's review
- Rebased series on v5.11-rc1 and dropped the already merged patches:
 * dt-bindings: mmc: owl: Add compatible string for Actions Semi S500 SoC
 * dt-bindings: i2c: owl: Convert Actions Semi Owl binding to a schema
 * MAINTAINERS: Update entry for Actions Semi Owl I2C binding
 * i2c: owl: Add compatible for the Actions Semi S500 I2C controller

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

Applied all patches except the 2 dmaengine patches for v5.12. Andreas, please
let me know if you want to do the PR this time. Else I'll proceed.

Thank you, Mani!
The dmaengine patches should be picked up by Vinod, right?
