> AST2700 is the 8th generation of Integrated Remote Management Processor
> introduced by ASPEED Technology Inc. It is a Board Management Controller
> (BMC) SoC family with a dual-die architecture:
> SoC0 ("CPU" die with four ARM Cortex-A35 application cores) and
> SoC1 ("IO" die with peripherals) each SoC have its own SCU PLLs, clock dividers
> and reset domains.

> Changes in v3:
> - mach: add "N: ast2700" to the ARM ASPEED MAINTAINERS entry.
> - Link to v2:
> https://lore.kernel.org/r/20260520-ast2700_clk-v2-0-c778b2908e5e@aspeedte
> ch.com
> Changes in v2:
> - v1 only have clk driver, v2 apply full AST2700 platform and
> reset, clk, ram driver.
> - Move scu_ast2700.h from the clk patch into the mach-aspeed
> - patch so the SoC header is provided alongside the SoC code
> that consumes it.
