[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:

[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.

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

[Juan Carlos Gutiérrez]

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:

https://lore.kernel.org/all/20260911-b4-spc-glee-a64-v1-v2-0-ed0b7ff02e0b@proton.me/

Best regards,
Juan Carlos
