[PATCH 0/4] arm64: dts: allwinner: add A733/Cubie A7S DTS support

[Enzo Adriano via B4 Relay]

This series adds initial devicetree support for the Allwinner A733 SoC and
Radxa Cubie A7S board.

It includes the Radxa Cubie A7S board compatible, the A733 MMC compatible,
an initial A733 SoC DTSI with CPUs, timer, GICv3, RTC oscillator provider,
CCU/R-CCU, pinctrl, UART0, and SDMMC0, and a board DTS enabling UART0 console
and SD card boot storage.

This series intentionally does not carry local CCU/PRCM or pinctrl driver
patches. Those areas overlap active A733 RFC work and remain external
prerequisites unless maintainers ask for a different plan. The A733 CCU RFC
also depends on the A733 RTC series.

Ethernet, VPU/Cedrus, display, Wi-Fi, Bluetooth, USB-C, PCIe, and other board
peripherals are intentionally out of scope. Vendor U-Boot workarounds used for
local proof collection are not encoded in these device trees.

Cubie A7S runtime proof has shown the v4 Image and DTB loading, Linux
7.1.0-rc6-gabc8d07b0a63, Radxa Cubie A7S machine model, 8 CPUs, GICv3
redistributors, A733 pinctrl/UART0, SDMMC0 enumeration, mmcblk0 partition
discovery, and a read-only mmcblk0p3 root mount via the corrected PARTUUID
path.
