[PATCH v3 0/5] arm: aspeed: add initial AST2700 SoC support

[Ryan Chen]

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@aspeedtech.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.
