dt-bindings: mtd: remove pxa3xx NAND controller documentation 



The deprecated pxa3xx_nand.c driver does not exist anymore, it has been
replaced by marvell_nand.c which has its own up-to-date documentation.

PXA3xx NAND DT bindings



Required properties:



 - compatible:		Should be set to one of the following:

			marvell,pxa3xx-nand

			marvell,armada370-nand

			marvell,armada-8k-nand

 - reg: 		The register base for the controller

 - interrupts:		The interrupt to map

 - #address-cells:	Set to <1> if the node includes partitions

 - marvell,system-controller: Set to retrieve the syscon node that handles

			NAND controller related registers (only required

			with marvell,armada-8k-nand compatible).



Optional properties:



 - dmas:			dma data channel, see dma.txt binding doc

 - marvell,nand-enable-arbiter:	Set to enable the bus arbiter

 - marvell,nand-keep-config:	Set to keep the NAND controller config as set

				by the bootloader

 - num-cs:			Number of chipselect lines to use

 - nand-on-flash-bbt: 		boolean to enable on flash bbt option if

				not present false

 - nand-ecc-strength:           number of bits to correct per ECC step

 - nand-ecc-step-size:          number of data bytes covered by a single ECC step



The following ECC strength and step size are currently supported:



 - nand-ecc-strength = <1>, nand-ecc-step-size = <512>

 - nand-ecc-strength = <4>, nand-ecc-step-size = <512>

 - nand-ecc-strength = <8>, nand-ecc-step-size = <512>



Example:



	nand0: nand@43100000 {

		compatible = "marvell,pxa3xx-nand";

		reg = <0x43100000 90>;

		interrupts = <45>;

		dmas = <&pdma 97 0>;

		dma-names = "data";

		#address-cells = <1>;



		marvell,nand-enable-arbiter;

		marvell,nand-keep-config;

		num-cs = <1>;



		/* partitions (optional) */

	};
