[PATCH 0/2] Add SPC Glee 10.1 A64 board support

[Juan Carlos Gutiérrez Lavado via B4 Relay]

Add initial mainline support for the SPC Glee 10.1 tablet, based on the
Allwinner A64 and AXP803 PMIC.

The board description covers the 2 GiB DRAM configuration, essential
CPU and system rails, microSD, UART, battery monitoring and USB device
mode. Other peripherals remain disabled until independently validated.

The microSD slot deliberately uses broken-cd and a conservative 25 MHz
limit because its card-detect wiring and higher-speed modes have not been
validated independently. USB is limited to the tested peripheral role.

The exact DTB produced by this series was cold-booted from microSD with
Linux 7.3.0-rc1. The kernel detected all four CPU cores and 2 GiB RAM,
probed the AXP803 over RSB, detected the microSD card, mounted the ext4
root filesystem and started systemd. The boot command line did not use
regulator_ignore_unused. No eMMC access was required.

Validation was run against sunxi/for-next at commit 913f7eda9f3e:

  make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig
  make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image \

[PATCH 2/2] arm64: dts: allwinner: Add SPC Glee 10.1 A64

[Juan Carlos Gutiérrez Lavado via B4 Relay]

From: Juan Carlos Gutiérrez Lavado <jcarlosgl96@proton.me>

Add support for the SPC Glee 10.1 tablet based on the Allwinner
A64. Describe the 2 GiB of DRAM, AXP803 PMIC, essential CPU and
system rails, microSD slot, UART console, battery monitoring and USB
peripheral port. Leave eMMC and unverified peripherals disabled.

This configuration was boot-tested from microSD to Arch Linux ARM
userspace without regulator_ignore_unused.

arm64: dts: allwinner: Add SPC Glee 10.1 A64

Add support for the SPC Glee 10.1 tablet based on the Allwinner A64. It
describes essential components including the PMIC, microSD, UART, and USB.

[Severity: Medium]
Does this board device tree omission break CPUfreq and thermal cooling?

By omitting the sun50i-a64-cpu-opp.dtsi include here, the board device tree
includes the base SoC definitions but lacks the CPU operating points required
for cpufreq and thermal management.

During boot, the thermal and cpufreq-dt drivers will probe the CPU nodes but
find no operating-points-v2 property. This can cause the cpufreq driver to
abort initialization, leaving the CPU pinned to the fixed bootloader
frequency and preventing the registration of CPU cooling devices. The thermal
framework would then be unable to actively throttle the CPU, which may risk
thermal trip shutdowns under load and degrade battery life.

Should the sun50i-a64-cpu-opp.dtsi file be included here?

[Severity: Medium]
Does enabling the usbphy without enabling the usb_power_supply break USB
charger detection?

The usbphy node is enabled, but the required &usb_power_supply node (which
monitors VBUS on the PMIC) is completely omitted and not linked via
usb0_vbus_power-supply.

Because the AXP803 PMIC's USB power supply node defaults to disabled in
axp803.dtsi, failing to override it to okay in the board file means the AXP
USB power supply driver (axp20x_usb_power) will not probe.

As a result, userspace tools will not know when a USB charger is connected.
Furthermore, without being linked to the usbphy, the USB PHY driver will
forcefully assume VBUS is always present, which could cause erratic USB
peripheral state transitions when unplugged.

Typically we look for these to match the vendor's website, which I think
in this case would be onspc?

Hi Conor,

Thanks for the review. I have changed the vendor prefix to onspc and
updated the board compatible accordingly in v2, which I have just sent:
