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

[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
