Further revision with a further few small formatting fixes. Major v5..v6 change is removal of the SD2 card node, given the requirements for low-voltage signalling are not fully elucidated and 3.3v operation, although working, was reliant on incorrect regulator node definitions.
Original cover below.

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 and NMI pins, with 4x Cortex-A53 Cores and a Mali G31 GPU)
- 1 GB LPDDR4 DRAM
- AXP717 PMIC (patches accepted in mfd-next [1])
- 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.
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.
