Subject: [PATCH v5 0/4] arm64: dts: allwinner: Add Anbernic RG35XX (Plus/H/2024) support
Date: Sat, 27 Apr 2024 09:35:05 +1200 [thread overview]
Message-ID: <20240426213505.69273-5-ryan@testtoast.com> (raw)
Thanks again for additional reviews. Have made the requested changes, and added some commentary about the SD2 low-voltage signalling, which will require a GPIO-switched regulator for the 3.3v->1.8v transition. This is not yet implemented/modeled, so for now a fixed 3.3v supply is used, and noted that an additional regulator define is required for SD2 operation and stable Bluetooth. However SD2, Wifi and BT are all working with the current state.
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.
