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.

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.
