[PATCH v4 0/2] arm: dts: sunxi: Add ICnova A20 ADB4006 board support

[Ludwig Kormann]

Add board support for ICnova A20 SomPi compute module on
ICnova ADB4006 development board.

I rebased the series on v6.4-rc1, I'm also using a new
mail address because of bouncing issues.

v4:
- rebase on v6.4-rc1

v3:
- drop stray blank lines at end of files
- separate patch for bindings
- update licensing to "GPL-2.0 OR MIT"
- fix typo: ICNova -> ICnova

v2:
- use short licensing header
- remove deprecated elements from led nodes
- disable csi power supply
- add missing pins in usbphy node
- split dts into SoM dtsi and carrier board dts

v1 of this patch was sent to the uboot mailing list [1].
