Hey,

Firstly your $subject should have a space after each :

Can you add this in alphanumerical order please?

"jh7110 framework" is not a real compatible (you need a vendor prefix
and no spaces) nor is it documented - which produces warnings:
arch/riscv/boot/dts/starfive/jh7110-framework.dtb: /: compatible: 'oneOf' conditional failed, one must be fixed:
        'jh7110 framework' is not one of ['beagle,beaglev-starlight-jh7100-r0', 'starfive,visionfive-v1']
        'jh7110 framework' is not one of ['milkv,mars', 'pine64,star64', 'starfive,visionfive-2-v1.2a', 'starfive,visionfive-2-v1.3b']
        'starfive,jh7100' was expected
        from schema $id: http://devicetree.org/schemas/riscv/starfive.yaml#
arch/riscv/boot/dts/starfive/jh7110-framework.dtb: /: compatible:0: 'jh7110 framework' does not match '^[a-zA-Z0-9][a-zA-Z0-9,+\\-._/]+$'
        from schema $id: http://devicetree.org/schemas/dt-core.yaml#
arch/riscv/boot/dts/starfive/jh7110-framework.dtb: /: failed to match any schema with compatible: ['jh7110 framework', 'starfive,jh7110']

Please run dtbs_check on future versions and fix reported warnings
by documenting things in dt-bindings.
"jh7110 framework" isn't very specific, so if there's a model number
attached to the mainboard that'd be good to have. The vendor in the
vendor prefix should be deepcomputing, so you'll likely have to add a
new vendor prefix for that.

The model field could also be improved, check out the visionfive 2 and
see how that property was written there.

What does the comment here mean?

Cheers,
