1 | NXP LPC32xx SoC NAND SLC controller | ||
2 | |||
3 | Required properties: | ||
4 | - compatible: "nxp,lpc3220-slc" | ||
5 | - reg: Address and size of the controller | ||
6 | - nand-on-flash-bbt: Use bad block table on flash | ||
7 | - gpios: GPIO specification for NAND write protect | ||
8 | |||
9 | The following required properties are very controller specific. See the LPC32xx | ||
10 | User Manual: | ||
11 | - nxp,wdr-clks: Delay before Ready signal is tested on write (W_RDY) | ||
12 | - nxp,rdr-clks: Delay before Ready signal is tested on read (R_RDY) | ||
13 | (The following values are specified in Hz, to make them independent of actual | ||
14 | clock speed:) | ||
15 | - nxp,wwidth: Write pulse width (W_WIDTH) | ||
16 | - nxp,whold: Write hold time (W_HOLD) | ||
17 | - nxp,wsetup: Write setup time (W_SETUP) | ||
18 | - nxp,rwidth: Read pulse width (R_WIDTH) | ||
19 | - nxp,rhold: Read hold time (R_HOLD) | ||
20 | - nxp,rsetup: Read setup time (R_SETUP) | ||
