The base model RG35XX (2024) is a handheld gaming device based on an Allwinner H700 chip. The H700 is a H616 variant (4x ARM Cortex-A53 cores @ 1.5Ghz with Mali G31 GPU) which exposes RGB LCD and NMI pins. Device features: - Allwinner H700 @ 1.5GHz - 1GB LPDDR4 DRAM - X-Powers AXP717 PMIC - 3.5" 640x480 RGB LCD - Two microSD slots - Mini-HDMI out - GPIO keypad - 3.5mm headphone jack Enabled in this DTS: - AXP717 PMIC with regulators (interrupt controller TBC/TBD) - Power LED (charge LED on device controlled directly by PMIC) - Serial UART (accessible from PIN headers on the board) - MMC slots Changelog v1..v2: - Update copyright - Spaces -> Tabs - Add cpufreq support [1] - Remove MMC aliases - Fix GPIO button and regulator node names - Note unused AXP717 regulators - Update regulator for SD slots - Remove unused I2C3 device - Update NMI interrupt controller for AXP717 [2] - Add chassis-type - Address USB EHCI/OHCI0 correctly and add usb vbus supply - Add PIO vcc-pg-supply - Correct boost regulator voltage and name Signed-off-by: Ryan Walklin <ryan@xxxxxxxxxxxxx> [1]: https://lore.kernel.org/linux-sunxi/20240419071450.7aiheeoyq35yjoo7@vireshk-i7/T/#t [2]: https://lore.kernel.org/linux-sunxi/20240418181615.1370179-1-macroalpha82@xxxxxxxxx/T/#t Signed-off-by: Ryan Walklin <ryan@xxxxxxxxxxxxx> --- .../sun50i-h700-anbernic-rg35xx-2024.dts | 375 ++++++++++++++++++ 1 file changed, 375 insertions(+) create mode 100644 arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts diff --git a/arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts b/arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts new file mode 100644 index 000000000000..d8081273677d --- /dev/null +++ b/arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts @@ -0,0 +1,375 @@ +// SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +/* + * Copyright (C) 2024 Ryan Walklin <ryan@xxxxxxxxxxxxx>. + */ + +/dts-v1/;
