[PATCH v5 0/5] Introduce ASPEED AST2700 BMC SoC

[PATCH v5 0/5] Introduce ASPEED AST2700 BMC SoC

[Ryan Chen]

This introduces initial support for the Aspeed AST2700 SoC and the AST2700
Evaluation Board (EVB) to the Linux kernel. The AST27XX is the 8th
generation Baseboard Management Controller (BMC) SoC from Aspeed,
featuring improved performance, enhanced security, and expanded I/O
capabilities compared to previous generations.

AST27XX SOC Family
 - https://www.aspeedtech.com/server_ast2700/
 - https://www.aspeedtech.com/server_ast2720/
 - https://www.aspeedtech.com/server_ast2750/

Bindings Dependencies:
- intc-ic: Documentation/devicetree/bindings/interrupt-controller/aspeed,ast2700-intc.yaml
- scu/silicon-id: Documentation/devicetree/bindings/mfd/aspeed,ast2x00-scu.yaml
- gpio: Documentation/devicetree/bindings/gpio/aspeed,ast2400-gpio.yaml
- mdio: Documentation/devicetree/bindings/net/aspeed,ast2600-mdio.yaml

v5:
- modify ast27XX 7th generation description to 8th generation.
- aspeed.yaml
 - modify missing blank line.
- Kconfig.platforms
 - modify ast27XX 7th generation to 8th generation.

v4:
- make CHECK_DTBS=y arch/arm64/boot/dts/aspeed/ fix.
- modify commit message remove itemlize.
- remove modify aspeed,ast2700-intc.yaml patch.
- aspeed.yaml
 - Add AST2700 board compatible.
- aspeed-g7.dtsi
 - modify all size-cells from 1 to 2.
 - add serial aliases, gpio, mdio, uart0 ~ 14.
 - add firmware for optee, reserved memory for atf and optee.
 - modify cpu@0 to cpu0: cpu@0.
 - fix intc-ic for yaml dependency.
- ast2700-evb.dts
 - update stdout-path = "serial12:115200n8";

v3:
- https://lore.kernel.org/all/20241212155237.848336-1-kevin_chen@aspeedtech.com/
- Split clk and reset driver to other commits, which are in series of
  "Add support for AST2700 clk driver".
- For BMC console by UART12, add uart12 using ASPEED INTC architecture.

aspeed,ast2700-intc.yaml
- Add minItems to 1 to fix the warning by "make dtbs_check W=1".
- Add intc1 into example.

Kconfig.platforms
  - Remove MACH_ASPEED_G7.

[PATCH v5 1/5] dt-bindings: arm: aspeed: Add AST2700 board compatible

[Ryan Chen]

Add device tree compatible string for AST2700 based boards
("aspeed,ast2700-evb" and "aspeed,ast2700") to the Aspeed SoC
board bindings. This allows proper schema validation and
enables support for AST2700 platforms.

Messed order. We already asked in other patches to keep alphabetical
order when extending entries.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/v6.17-rc1 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
