1 Atmel NAND flash controller bindings
3 The NAND flash controller node should be defined under the EBI bus (see
5 One or several NAND devices can be defined under this NAND controller.
6 The NAND controller might be connected to an ECC engine.
8 * NAND controller bindings:
12 	"atmel,at91rm9200-nand-controller"
13 	"atmel,at91sam9260-nand-controller"
14 	"atmel,at91sam9261-nand-controller"
15 	"atmel,at91sam9g45-nand-controller"
16 	"atmel,sama5d3-nand-controller"
17 	"microchip,sam9x60-nand-controller"
30 * NAND device/chip bindings:
33 - reg: describes the CS lines assigned to the NAND device. If the NAND device
36        1st entry: the CS line this NAND chip is connected to
42 - rb-gpios: the GPIO(s) used to check the Ready/Busy status of the NAND.
64 SAMA5 SoCs embed an advanced NAND controller logic to automate READ/WRITE page

133 - atmel,nand-addr-offset : offset for the address latch.
134 - atmel,nand-cmd-offset : offset for the command latch.
138 - gpios : specifies the gpio pins to control the NAND device. detect is an
142 - atmel,nand-has-dma : boolean to support dma transfer for nand read/write.
143 - nand-ecc-mode : String, operation mode of the NAND ecc mode, soft by default.
150   is "atmel,sama5d2-nand", 32 is also valid.
156 - nand-bus-width : 8 or 16 bus width if not present 8
157 - nand-on-flash-bbt: boolean to enable on flash bbt option if not present false
159 Nand Flash Controller(NFC) is an optional sub-node
