* Qualcomm NAND controller Required properties: - compatible: should be "qcom,ipq806x-nand" - reg: MMIO address range - clocks: must contain core clock and always on clock - clock-names: must contain "core" for the core clock and "aon" for the always on clock - dmas: DMA specifier, consisting of a phandle to the ADM DMA controller node and the channel number to be used for NAND. Refer to dma.txt and qcom_adm.txt for more details - dma-names: must be "rxtx" - qcom,cmd-crci: must contain the ADM command type CRCI block instance number specified for the NAND controller on the given platform - qcom,data-crci: must contain the ADM data type CRCI block instance number specified for the NAND controller on the given platform - #address-cells: <1> - subnodes give the chip-select number - #size-cells: <0> * NAND chip-select Each controller may contain one or more subnodes to represent enabled chip-selects which (may) contain NAND flash chips. Their properties are as follows. Required properties: - compatible: should contain "qcom,nandcs" - reg: a single integer representing the chip-select number (e.g., 0, 1, 2, etc.) - #address-cells: see partition.txt - #size-cells: see partition.txt - nand-ecc-strength: see nand.txt - nand-ecc-step-size: must be 512. see nand.txt for more details. Optional properties: - nand-bus-width: see nand.txt Each nandcs device node may optionally contain a 'partitions' sub-node, which further contains sub-nodes describing the flash partition mapping. See partition.txt for more detail. Example: nand@1ac00000 { compatible = "qcom,ebi2-nandc"; reg = <0x1ac00000 0x800>; clocks = <&gcc EBI2_CLK>, <&gcc EBI2_AON_CLK>; clock-names = "core", "aon"; dmas = <&adm_dma 3>; dma-names = "rxtx"; qcom,cmd-crci = <15>; qcom,data-crci = <3>; #address-cells = <1>; #size-cells = <0>; nandcs@0 { compatible = "qcom,nandcs"; reg = <0>; nand-ecc-strength = <4>; nand-ecc-step-size = <512>; nand-bus-width = <8>; partitions { compatible = "fixed-partitions"; #address-cells = <1>; #size-cells = <1>; partition@0 { label = "boot-nand"; reg = <0 0x58a0000>; }; partition@58a0000 { label = "fs-nand"; reg = <0x58a0000 0x4000000>; }; }; }; };
