|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "qcom,msm-nand".
|
||
|
|
- reg : should specify QPIC NANDc and BAM physical address range.
|
||
|
|
- reg-names : should specify relevant names to each reg property defined.
|
||
|
|
- interrupts : should specify QPIC/BAM interrupt numbers.
|
||
|
|
- interrupt-names : should specify relevant names to each interrupts property
|
||
|
|
defined.
|

MTD flash partition layout for NAND devices -
|
||
|
|
|
||
|
|
Each partition is represented as a sub-node of the qcom,mtd-partitions device.
|
||
|
|
Each node's name represents the name of the corresponding partition.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- reg : The partition offset and size
|
||
|
|
- label : The label / name for this partition.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- read-only: This parameter, if present, indicates that this partition
|
||
|
|
should only be mounted read-only.
|
||
|
|
|
||
|
|
