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 - USB-C charging port Enabled in this DTS: - AXP717 PMIC with RSB serial interface, regulators and NMI interrupt controller - Power LED (charge LED on device controlled directly by PMIC) - Serial UART (accessible from headers on the board) - First SD slot (SD2 appears to have a GPIO-switched regulator for 1.8v low-voltage signalling, this is not yet modeled. Enablement with a switched regulator will be confirmed and posted in a follow-up patch). Signed-off-by: Ryan Walklin Reviewed-by: Jernej Skrabec --- Changelog v1..v2: - Update copyright - Spaces -> Tabs - Add cpufreq support - Remove MMC aliases - Fix GPIO button and regulator node names - Note unused AXP717 regulators - Update regulators for SD slots - Remove unused I2C3 device - Update NMI interrupt controller for AXP717, requires H616 support patch in dt-next [1] - Add chassis-type - Address USB EHCI/OHCI0 correctly and add usb vbus supply - Add PIO vcc-pg-supply - Correct boost regulator voltage and name Changelog v2..v3: - Remove cpufreq support (patch still pending for 6.10, will followup with enablement patch once opp table merged) - Add dtb to Makefile - Remove unnecessary duplicated PLL regulator - Remove unimplemented/not-present drive-vbus feature from AXP717 - Rename CLDO3 to "vcc-io", inferring function from board testing by Chris Morgan - Correct MMC1 vmmc-supply to CLDO3 and MMC2 to CLDO4 - Reduce DCDC1 "vdd-cpu" supply voltage range to 0.9v-1.1v to match lowest OPP voltage - Identify DCDC2 as GPU supply - rename to "vdd-gpu-sys", remove always-on and use fixed 0.94v voltage - Fix indentation - Correct boot/always-on states and voltages for various regulators from vendor BSP - Change USB-OTG mode to "peripheral" and correct comment - Correct and add remaining PIO supplies - Move volume key GPIOs to separate block to allow key repeat - Alphabetically orrder gamepad GPIOs - Move changelog and links below fold-line - Remove USB 3.3v VCC-USB and VCC-SD2 regulators pending further hardware investigation (to be submitted as subsequent patch) - Constrain boost regulator voltage to 5.0v to 5.2v to capture default voltage of 5.126v Changelog v3..v4: - Cluster USB nodes - Do not define voltage range for currently unused CLDO1 (connected to audio codec according to vendor BSP - driver not yet implemented) and ALDO3 (1.8v). - Note voltages set for currently unused regulators from vendor BSP in comments to aid identification - Remove regulator-boot-on from several regulators where it was not required - Fix indentation - Add "disable-wp" for SD2 as for SD1 (doesn't make sense for micro-SD) - Restore fixed 3.3v regulator for SD2 (vcc_3v3_sd2), which is required for SD2 to function. ALDO1 appears to be the 1.8v supply required for low-voltage UHS-I signalling, however a GPIO pin to switch between the supplies is not yet confirmed (likely PE4) and will be implemented in a subsequent patch. Changelog v4..v5: - Remove comment referencing vendor BSP node - Reorder nodes alphabetically and remove empty lines - Add note to commit message about SD2 regulators, rename vcc_3v3_sd2 Changelog v5..v6: - Remove SD2 slot and regulator definitions until confirmation of regulator/GPIO states required for LV signalling switching - Re-sort nodes [1]: https://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git/commit/?h=dt/next&id=d47bca77bf3ab475c33b3929c33c80aeb49df35c Signed-off-by: Ryan Walklin --- arch/arm64/boot/dts/allwinner/Makefile | 1 + .../sun50i-h700-anbernic-rg35xx-2024.dts | 327 ++++++++++++++++++ 2 files changed, 328 insertions(+) create mode 100644 arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts diff --git a/arch/arm64/boot/dts/allwinner/Makefile b/arch/arm64/boot/dts/allwinner/Makefile index 21149b346a60..6f997157968e 100644 --- a/arch/arm64/boot/dts/allwinner/Makefile +++ b/arch/arm64/boot/dts/allwinner/Makefile @@ -47,3 +47,4 @@ dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h618-longanpi-3h.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h618-orangepi-zero2w.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h618-orangepi-zero3.dtb dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h618-transpeed-8k618-t.dtb +dtb-$(CONFIG_ARCH_SUNXI) += sun50i-h700-anbernic-rg35xx-2024.dtb 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..ee30584b6ad7 --- /dev/null +++ b/arch/arm64/boot/dts/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts @@ -0,0 +1,327 @@ +// SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +/* + * Copyright (C) 2024 Ryan Walklin . + */ + +/dts-v1/;
