- You need #address-cells and #size-cells in bus nodes.
#address-cells should be <2> in fsl,lpb nodes. Your ranges property
is broken due to the missing #address/size-cells.

- since address cells will be '2', you need 2 cells to describe the
base address here; first cell is the chip select, second cell is the
address offset off that base address.
