Now that you mention it, ps20 and ps21 do not follow follow the rising
address order.

        uart7: serial@...29c00 {
            ...
        i2c0: i2c@...2ac00 {
            ...
        i2c1: i2c@...2b000 {
            ...
        i2c2: i2c@...2b400 {
            ...
        can0: can@...2bc00 {
            ...
        ps20: ps2@...2a000 {
            ....
        ps21: ps2@...2a400 {
            ...
       
The correct order would be
uart7, ps20, ps21, i2c0, i2c1, i2c2, can0 .

I'll fix that in patch v4.

Thanks,
Patrick
