1* Chipselect/Local Bus
2
3Properties:
4- name : Should be localbus
5- #address-cells : Should be either two or three.  The first cell is the
6                   chipselect number, and the remaining cells are the
7                   offset into the chipselect.
8- #size-cells : Either one or two, depending on how large each chipselect
9                can be.
10- ranges : Each range corresponds to a single chipselect, and cover
11           the entire access window as configured.
