[PATCH v6 0/2] arm64: dts: allwinner: h616: Add Mango Pi MQ-Quad DTS

[Matthew Croughan]

V1: Submission
V2: Alphabetical ordering, added "widora,mangopi-mq-quad" compatible
V3: Added Signed-off-by, add to device-tree compatible/bindings documentation
V4:
- Add separate patch for bindings documentation
- Regularised comment style
- Add vcc supplies for gpio according to board schematic
- Removed unnecessary x-powers,self-working-mode;
- Added comment regarding ALDO1
- Removed unnecessary reg_dldo1 regulator, it seems to be connected to nothing
  in the schematic, no adverse effects observed
V5:
- Switch ordering of patches
- Fix comment style
- Add Reviewed-by tag
V6:
- Corrected Reviewed-by tags on commits
- pass #interrupt-cells = <1> to axp313a
- pass interrupt-controller to axp313a

There is no point having device node with properties but without compatible. 
You also don't provide any ethernet alias, which would allow U-Boot to add MAC 
property.

In any case, rtw88 driver now supports rtl8723ds, but it's loaded based on 
SDIO ID. It doesn't take any info from DT yet.

I suggest that you drop it for now and if/when rtw88 driver gains support for 
taking GPIO property for host wakeup, it's added then.

Best regards,
Jernej
