| NXP LPC32xx SoC NAND MLC controller |
| |
| Required properties: |
| - compatible: "nxp,lpc3220-mlc" |
| - reg: Address and size of the controller |
| - interrupts: The NAND interrupt specification |
| - gpios: GPIO specification for NAND write protect |
| |
| The following required properties are very controller specific. See the LPC32xx |
| User Manual 7.5.14 MLC NAND Timing Register (the values here are specified in |
| Hz, to make them independent of actual clock speed and to provide for good |
| accuracy:) |
| - nxp,tcea_delay: TCEA_DELAY |
| - nxp,busy_delay: BUSY_DELAY |
| - nxp,nand_ta: NAND_TA |
| - nxp,rd_high: RD_HIGH |
| - nxp,rd_low: RD_LOW |
| - nxp,wr_high: WR_HIGH |
| - nxp,wr_low: WR_LOW |
| |
| Optional subnodes: |
| - Partitions, see Documentation/devicetree/bindings/mtd/partition.txt |

| interrupts = <11 0>; |
| #address-cells = <1>; |

| nxp,nand-ta = <18181818>; |
| nxp,rd-high = <31250000>; |
| nxp,rd-low = <45454545>; |
| nxp,wr-high = <40000000>; |
| nxp,wr-low = <83333333>; |
| gpios = <&gpio 5 19 1>; /* GPO_P3 19, active low */ |
