[PATCH 0/3] arm64: dts: airoha: add AN7589 support

[John Crispin]

The Airoha AN7589 is a quad Cortex-A73 SoC. This series adds its board
compatibles, a base SoC dtsi with the CPUs, PSCI, the GICv3, the
architected timer and the console UART, and the device tree of the
evaluation board with 2 GiB of DRAM.

The remaining blocks follow with the series of their drivers.

The series applies to next-20261105 and has no dependencies.

[PATCH 2/3] arm64: dts: airoha: add AN7589 SoC dtsi

[John Crispin]

Add the device tree for the Airoha AN7589 SoC. It describes the four
Cortex-A73 cores, which the firmware brings up over PSCI, the GICv3, the
architected timer and the console UART.

The UART runs from a fixed 1.8432 MHz clock, so the console works
before the SCU clock controller probes. The remaining blocks follow later.
