There is already a real partitions.yaml file, so assuming everybody
knows hot to read yaml schema now, this text file is no longer needed,
so drop it.
Depending on the situation, the lines referring to this file are either
dropped or edited to point to mtd.yaml which includes partition{,s}.yaml.

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)
|
|
|
