[PATCH 0/4] arm64: dts: allwinner: Add Anbernic RG35XX (Plus/H/2024) support

[Ryan Walklin <ryan@testtoast.com>]

From: Ryan Walklin <ryan@testtoast.com>

The Anbernic RG35XX is a family of handheld gaming devices. There are 4 
variants, of which 3 using the Allwinner H700 chip are covered by this patchset.
The fourth (released first and named simply RG35XX) uses an Actions 
Semiconductor ATM7039s which is a 32-bit Cortex-A9 chip with no mainline support 
and is not covered.

Common features (RG35XX-2024):
- Allwinner H700 @ 1.5GHz (H616 variant exposing RGB LCD pins, with 4x 
  Cortex-A53 Cores and a Mali G31 GPU)
- 1 GB LPDDR4 DRAM
- AXP717 PMIC (patches accepted in mfd-next - 
  https://kernel.googlesource.com/pub/scm/linux/kernel/git/lee/mfd/+/d2ac3df75c3a995064cfac0171e082a30d8c4c66)
- 3.5" 640x480 RGB LCD
- Mini-HDMI, 3.5mm audio jack, mono speaker, two microSD slots and USB-C 
  (USB 2.0) for power.

RG35XX-Plus adds:
- RTL8821CS SDIO Wifi/BT chip

RG35XX-H (Horizontal form-factor) adds:
- RTL8821CS SDIO Wifi/BT chip
- Two analog thumbsticks
- Second USB-C port
- Stereo speaker

Patch 1 adds the DT bindings for the board names, Patch 2 adds the -2024 device
as a common base, Patch 3 adds Wifi/BT support for the -Plus (and -H), and Patch 
3 adds the second USB and thumbsticks for the -H. The -H is a strict superset of
the -Plus, which is in turn a strict superset of the -2024, so this translates 
quite neatly. Alternatively a single DTS for the three devices could be 
considered.

LCD, HDMI, audio and GPU support are not yet ready and relying on out-of-tree 
patches currently, so will be added once these drivers are mainlined.
