[PATCH v6 0/4] arm64: dts: allwinner: Add Anbernic RG35XX (Plus/H/2024) support

[Ryan Walklin]

Further revision with a further few small formatting fixes. Major v5..v6 change is removal of the SD2 card node, given the requirements for low-voltage signalling are not fully elucidated and 3.3v operation, although working, was reliant on incorrect regulator node definitions.

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 v6 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)
- 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).

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

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

> 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.

The -H is a strict superset of the -Plus, which is in turn a strict superset of the -2024, so this translates quite neatly.
