Hi @mamingrui123. Thanks for your PR.

I'm waiting for a deepin-community member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Pull request overview

This PR adds Device Tree Source (DTS) files for several new Phytium ARM64 SoCs (pd2408, pd2308, ps2316) and their corresponding development boards. It registers the new dtb targets in the existing phytium Makefile.

Changes:

Add new SoC dtsi files: pd2408-generic-psci-soc.dtsi, pd2308.dtsi, ps2316-generic-psci-soc.dtsi.
Add board dts files: pd2408-devboard-d4-dsk.dts, pd2308-demo-a.dts, pd2308-demo-b.dts, ps2316-devboard-16c-dsk.dts.
Update arch/arm64/boot/dts/phytium/Makefile to build the new dtb targets when CONFIG_ARCH_PHYTIUM is enabled.

The standard status values are "okay" and "disabled". While "ok" was supported as a deprecated alias, current DT specifications and dtc warn about it. The codebase mixes "ok" (in board override blocks) with "okay" (e.g. mmc0). Prefer "okay" consistently across all these new board dts files (pd2408-devboard-d4-dsk.dts, ps2316-devboard-16c-dsk.dts, pd2308-demo-a.dts, pd2308-demo-b.dts).

The compatible string "phytium,pd2308" is the same as the SoC compatible. Board dts files conventionally include a more-specific board compatible first followed by the SoC compatible, e.g. compatible = "phytium,pd2308-demo-a", "phytium,pd2308"; (as done in pd2408-devboard-d4-dsk.dts).

	compatible = "phytium,pd2308";
