1Freescale Localbus UPM programmed to work with NAND flash
2
3Required properties:
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.
8- gpios : may specify optional GPIO connected to the Ready-Not-Busy pin.
9
10Example:
11
12upm@1,0 {
13 compatible = "fsl,upm-nand";
14 reg = <1 0 1>;
15 fsl,upm-addr-offset = <16>;
16 fsl,upm-cmd-offset = <8>;
17 gpios = <&qe_pio_e 18 0>;
18
19 flash {
20 #address-cells = <1>;
21 #size-cells = <1>;
22 compatible = "...";
