| NXP LPC32xx SoC NAND SLC controller |
| |
| Required properties: |
| - compatible: "nxp,lpc3220-slc" |
| - reg: Address and size of the controller |
| - nand-on-flash-bbt: Use bad block table on flash |
| - gpios: GPIO specification for NAND write protect |
| |
| The following required properties are very controller specific. See the LPC32xx |
| User Manual: |
| - nxp,wdr-clks: Delay before Ready signal is tested on write (W_RDY) |
| - nxp,rdr-clks: Delay before Ready signal is tested on read (R_RDY) |
| (The following values are specified in Hz, to make them independent of actual |
| clock speed:) |
| - nxp,wwidth: Write pulse width (W_WIDTH) |
| - nxp,whold: Write hold time (W_HOLD) |
| - nxp,wsetup: Write setup time (W_SETUP) |
| - nxp,rwidth: Read pulse width (R_WIDTH) |
| - nxp,rhold: Read hold time (R_HOLD) |
| - nxp,rsetup: Read setup time (R_SETUP) |
| |
| Optional subnodes: |
| - Partitions, see Documentation/devicetree/bindings/mtd/mtd.yaml |
