DT unit addresses should be lower case hex. Fix all the
binding examples.

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
