AM625: RINGACC inside AM625x

Part Number: AM625

Tool/software:

Dear champ, 

Customer is asking what functions in RINGACC support and what are not supported. 

Is there a addendum or document for the detail?

Besides, customer found RINGACC is only seen in AM65x dtsi but not seen in AM62x dtsi and wonder whether AM62x does support RINGACC feature? 

BR, Rich
