description: >
The NAND controller should be represented with its own DT node, and
all NAND chips attached to this controller should be defined as
children nodes of the NAND controller. This representation should be
enforced even for simple controllers supporting only one chip.
This is only for legacy nand controller, new controller should use

description:
Array of chip-select available to the controller. The first
entries are a 1:1 mapping of the available chip-select on the
NAND controller (even if they are not used). As many additional
chip-select as needed may follow and should be phandles of GPIO
lines. 'reg' entries of the NAND chip subnodes become indexes of
this array when this property is present.
