| Qualcomm Parallel Interface controller (QPIC) for NAND devices |
| |
| 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. |
| |
| Examples: |
| |
| qcom,nand@f9af0000 { |
| compatible = "qcom,msm-nand"; |
| reg = <0xf9af0000 0x1000>, |
| <0xf9ac4000 0x8000>; |
| reg-names = "nand_phys", |
| "bam_phys"; |
| interrupts = <0 279 0>; |
| interrupt-names = "bam_irq"; |
| }; |
| |
| qcom,mtd-partitions { |
| #address-cells = <1>; |
| #size-cells = <1>; |
| partition@0 { |
| label = "boot"; |
| reg = <0x0 0x1000>; |
| read-only; |
| }; |
| partition@20000 { |
| label = "userdata"; |
| reg = <0x20000 0x1000>; |
| }; |
| partition@40000 { |
| label = "system"; |
| reg = <0x40000 0x1000>; |
| }; |
