[PATCH net-next v4 05/10] arm64: dts: rockchip: rk3568: add XPCS and fixed-clock nodes

[sashiko-bot at kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] Missing 'phy-names' and 'phys' properties in the XPCS node causes dtbs_check failures.
- [Low] The fixed-clock nodes use a deprecated naming convention.

arm64: dts: rockchip: rk3568: add XPCS and fixed-clock nodes

This commit adds the XPCS device node and its pcs-mii sub-nodes to the RK3568
SoC device tree, along with two fixed-clock nodes for the GMAC reference
clocks. The XPCS node is disabled by default and meant to be enabled at the
board level.

[Severity: Low]
Will this cause make dtbs_check failures during kernel builds? The dt-schema
tool unconditionally validates all nodes against rockchip-dwxpcs.yaml,
including those with status = "disabled".

Because phys and phy-names are strictly required by the binding, omitting
them here in rk3568.dtsi breaks DT validation for all RK3568 boards that
include this file without explicitly providing these properties.

[Severity: Low]
Could this node name trigger deprecation warnings during make dtbs_check?

The fixed-clock.yaml schema restricts valid node names to the pattern
^clock-([0-9]+|[a-z0-9-]+)$. Names outside this pattern, like
xpcs-gmac0-clock, fall under a legacy definition tagged as deprecated.

> +		compatible = "fixed-clock";

[Severity: Low]
Does this node name also trigger a deprecation warning for the same reason?
