[PATCH v8 0/4] Add support for NetCube Systems Kumquat

[PATCH v8 0/4] Add support for NetCube Systems Kumquat

[Lukas Schmid]

This series adds dt-bindings and dt's for the NetCube Systems Kumquat board

Changes in v2:
  - Fix the devicetrees according to the "dt-schema" and 
    "make dtbs_check W=1"
  - Fix the License of the devicetree as requested
  - Create a cover letter for the patch series

Changes in v3:
  - Disable rtc inside the SoC again, as the rtc does not work on the board
  - Add the gpio-reserved-ranges property to the pinctrl bindings
  - Reorder the nodes in the devicetree to match the order of the nodes in 
    the sun8i-v3s.dtsi file

Changes in v4:
  - Moved the dtsi change into a sperate patch
  - Update commit messages to include better descriptions
  - Add descriptions to the uarts and mmc nodes in the dts file
  - Add missing newline at the end of the dts file
  - Removed the gpio-reserved-ranges property from the dts and from the
    pinctrl bindings
  - Remove the rtc status property from the dts file

Changes in v5:
  - Remove the unused lradc node and it's regualtor, as they are not used
    on the board
  - Add another alias for the SoC's rtc as 'rtc1'

Changes in v6:
  - Add reason why DS3232+ is preferred over internal rtc
  - Remove redundant pinctrls from mmc0, mmc1 and i2c0
  - Reordered eeprom0 and spi0/flash@0 properties
  - Reordered nodes by their node name alias+

Changes in v7:
  - Disable the external 32kHz crystal oscillator, as it does not work on
    the board

Changes in v8:
  - Update the commit messages and cover letter according to the Linux
    coding style
