This is missing ti specific compatible. As we don't use the IP block
directly but there is a wrapper used to integrate with TI platform, so
it is better to use TI specific compatible too to account for the future
compatibility as discussed here [1]. You can refer AM62A device-tree [2]
for references on this.
