From: Ryan Walklin <ryan@xxxxxxxxxxxxx> 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.
