[PATCH 11/14] arm64: dts: allwinner: Add Allwinner A523 .dtsi file

Andre Przywara
2024-11-11T01:31:07Z

The Allwinner A523, and its siblings A527 and T527, which share the same
die, are a new family of SoCs introduced in 2023. They features eight
Arm Cortex-A55 cores, and, among the other usual peripherals, a PCIe and
USB 3.0 controller.

Add the basic SoC devicetree .dtsi for the chip, describing the
fundamental peripherals: the cores, GIC, timer, RTC, CCU and pinctrl.
Also some other peripherals are fully compatible with previous IP, so
add the USB and MMC nodes as well.
The other peripherals will be added in the future, once we understand
their compatibility and DT requirements.
