1 * Qualcomm NAND controller
4 - compatible:		must be one of the following:
5     * "qcom,ipq806x-nand" - for EBI2 NAND controller being used in IPQ806x
7     * "qcom,ipq4019-nand" - for QPIC NAND controller v1.4.0 being used in
9     * "qcom,ipq8074-nand" - for QPIC NAND controller v1.5.0 being used in
12 - reg:			MMIO address range
13 - clocks:		must contain core clock and always on clock
14 - clock-names:		must contain "core" for the core clock and "aon" for the
18 - dmas:			DMA specifier, consisting of a phandle to the ADM DMA
19 			controller node and the channel number to be used for
20 			NAND. Refer to dma.txt and qcom_adm.txt for more details
21 - dma-names:		must be "rxtx"

31 			and the channel number to be used for NAND. Refer to
33 - dma-names:		must contain all 3 channel names : "tx", "rx", "cmd"
34 - #address-cells:	<1> - subnodes give the chip-select number

37 * NAND chip-select
39 Each controller may contain one or more subnodes to represent enabled
40 chip-selects which (may) contain NAND flash chips. Their properties are as
44 - reg:			a single integer representing the chip-select
46 - #address-cells:	see partition.txt

55 Each nandcs device node may optionally contain a 'partitions' sub-node, which
56 further contains sub-nodes describing the flash partition mapping. See
