1 Freescale Localbus UPM programmed to work with NAND flash
4 - compatible : "fsl,upm-nand".
5 - reg : should specify localbus chip select and size used for the chip.
6 - fsl,upm-addr-offset : UPM pattern offset for the address latch.
7 - fsl,upm-cmd-offset : UPM pattern offset for the command latch.
10 - fsl,upm-wait-flags : add chip-dependent short delays after running the
11 UPM pattern (0x1), after writing a data byte (0x2) or after
12 writing out a buffer (0x4).
13 - fsl,upm-addr-line-cs-offsets : address offsets for multi-chip support.
14 The corresponding address lines are used to select the chip.
15 - gpios : may specify optional GPIOs connected to the Ready-Not-Busy pins
16 (R/B#). For multi-chip devices, "n" GPIO definitions are required
17 according to the number of chips.
18 - chip-delay : chip dependent delay for transfering data from array to
19 read registers (tR). Required if property "gpios" is not used
20 (R/B# pins not connected).
