I am on next-20260507
The serdes_wiz0 node here is bound by ti,phy-j721e-wiz.yaml (the node
uses compatible = "ti,am64-wiz-10g").  That binding has
additionalProperties: false and does not define ti,core-clk-sel,
ti,ssc-enable, ti,ssc-type, ti,ssc-frequency-hz, or
ti,ssc-depth-per-mil.
I see
arch/arm64/boot/dts/ti/k3-am642-hummingboard-t-usb3.dtb: wiz@f000000 (ti,am64-wiz-10g): 'ti,core-clk-sel', 'ti,ssc-depth-per-mil', 'ti,ssc-enable', 'ti,ssc-frequency-hz', 'ti,ssc-type' do not match any of the regexes: '^cmn-refclk1?-dig-div$', '^pinctrl-[0-9]+$', '^pll[0|1]-refclk$', '^serdes@[0-9a-f]+$'

and so on..

How does this series pass dtbs_check?
