[PATCH v4 0/4] arm64: dts: allwinner: Add Anbernic RG35XX (Plus/H/2024) support

[Ryan Walklin]

Further revised patchset based on review with many more corrections to regulators and formatting. Thanks to all reviewers.
Changelog inline, 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.

[PATCH v4 1/4] dt-bindings: arm: sunxi: document Anbernic RG35XX handheld gaming device variants

[Ryan Walklin]

RG35XX 2024: Base version with Allwinner H700
RG35XX Plus: Adds Wifi/BT
RG35XX H: Adds second USB port and analog sticks to -Plus in horizontal form factor

[PATCH v4 2/4] arm64: dts: allwinner: h700: Add RG35XX 2024 DTS

[Ryan Walklin]

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
- 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)
- MMC slots

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. CLDO4 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.

[PATCH v4 4/4] arm64: dts: allwinner: h700: Add RG35XX-H DTS

[Ryan Walklin]

The RG35XX-H adds thumbsticks, a stereo speaker, and a second USB port to the RG35XX-Plus, and has a horizontal form factor.

Enabled in this DTS:
- Thumbsticks
- Second USB port

Signed-off-by: Ryan Walklin <ryan@testtoast.com>
Reviewed-by: Andre Przywara <andre.przywara@arm.com>
---
Changelog v1..v2:
- Update copyright
- Spaces -> Tabs
- Add GP ADC joystick axes and mux [1]
- Add EHCI/OHCI1 for second USB port and add vbus supply

Changelog v2..v3:
- Add DTB to Makefile
- Remove USB vbus supply
- Remove GPADC joysticks until required patches land [1]
- Move thumbsticks into existing gpio gamepad node
- Move changelog and links below fold-line

Changelog v3..v4:
- Remove redundant USB OTG and PHY nodes.

Lines in commit messages should be limited to 75 characters per line, so
is there any chance you can break those two lines above here and that one
line down there?
Lines below the three dashes don't matter, since they won't make it into
the repo.

CLDO4 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.

This is still referencing the old regulator, I guess you wanted your new 
vcc_3v3_sd2 in here?
It's an easy fix, but it would be good to know if it still works.

Customarily the nodes referenced by alias in a board .dts are ordered
alphabetically. Even when this tears apart pairs like ohci and ehci.
