[PATCH 1/2] dt-bindings: arm: altera: deprecate intel,socfpga-agilex72

[PATCH 1/2] dt-bindings: arm: altera: deprecate intel,socfpga-agilex72

[Dinh Nguyen]

The Altera SoCFGPA Agilex72 platform will be rebranded as the Agilex27. Thus
the following bindings "intel,socfpga-agilex72" and "intel,socfpga-agilex72-socdk"
should no longer be used going forward, so we will deprecate them.

Replace those deprecated bindings with "altr,socfpga-agilex27" and
"altr,socfpga-agilex27-socdk" bindings for the SoCFPGA Agilex27 platform.

[PATCH 2/2] arm64: dts: altera: Add support for the Agilex27 SoCDK

[Dinh Nguyen]

The SoCFPGA Agilex72 platform is being renamed to Agilex27.

Remove the agilex72 base DTSI and agilex72 devkit dts and replace them with
an Agilex27 base DTSI and Agilex27 devkit dts.

arm64: dts: altera: Add support for the Agilex27 SoCDK

The SoCFPGA Agilex72 platform is being renamed to Agilex27. This commit
removes the agilex72 base DTSI and devkit DTS files, replacing them with
new ones for Agilex27.

[Severity: Medium]
Does removing the older compatible strings break devicetree ABI compatibility?

If existing bootloaders or user-space software expect to match against
intel,socfpga-agilex72 or intel,socfpga-agilex72-socdk, replacing them
entirely might cause them to fail to boot or bind to this board.

Should the old compatible strings be retained as a fallback in the root node
to ensure backward compatibility?
