+- name : Should be localbus
+- #address-cells : Should be either two or three. The first cell is the
+ chipselect number, and the remaining cells are the
+ offset into the chipselect.
+- #size-cells : Either one or two, depending on how large each chipselect
+ can be.
+- ranges : Each range corresponds to a single chipselect, and cover
+ the entire access window as configured.
+
+Example:

+ compatible = "fsl,mpc8272-localbus",
