The clock controller schemas for i.MX 8M Mini, 8M Nano, 8M Plus and 8M Quad are basically the same. The only minor difference appears on 8M Quad which needs one more clock. There is no point to have four schemas for almost the same binding. Any fixes or changes would have to be duplicated four times.
