| * Denali NAND controller |
| |
| Required properties: |
| - compatible : should be one of the following: |
| "altr,socfpga-denali-nand" - for Altera SOCFPGA |
| "socionext,uniphier-denali-nand-v5a" - for Socionext UniPhier (v5a) |
| "socionext,uniphier-denali-nand-v5b" - for Socionext UniPhier (v5b) |
| - reg : should contain registers location and length for data and reg. |
| - reg-names: Should contain the reg names "nand_data" and "denali_reg" |
| - #address-cells: should be 1. The cell encodes the chip select connection. |
| - #size-cells : should be 0. |
| - interrupts : The interrupt number. |
| - clocks: should contain phandle of the controller core clock, the bus |
| interface clock, and the ECC circuit clock. |
| - clock-names: should contain "nand", "nand_x", "ecc" |
| |
| Sub-nodes: |
| Sub-nodes represent available NAND chips. |
| |
| Required properties: |
| - reg: should contain the bank ID of the controller to which each chip |
| select is connected. |
| |
| Optional properties: |
| - nand-ecc-step-size: see nand-controller.yaml for details. |
| If present, the value must be |
| 512 for "altr,socfpga-denali-nand" |
| 1024 for "socionext,uniphier-denali-nand-v5a" |
| 1024 for "socionext,uniphier-denali-nand-v5b" |
| - nand-ecc-strength: see nand-controller.yaml for details. Valid values are: |
| 8, 15 for "altr,socfpga-denali-nand" |
| 8, 16, 24 for "socionext,uniphier-denali-nand-v5a" |
| 8, 16 for "socionext,uniphier-denali-nand-v5b" |
| - nand-ecc-maximize: see nand-controller.yaml for details |
| |
| The chip nodes may optionally contain sub-nodes describing partitions of the |
| address space. See partition.txt for more detail. |
| |
| Examples: |
| |
| nand: nand@ff900000 { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| compatible = "altr,socfpga-denali-nand"; |
| reg = <0xff900000 0x20>, <0xffb80000 0x1000>; |
| reg-names = "nand_data", "denali_reg"; |
| clocks = <&nand_clk>, <&nand_x_clk>, <&nand_ecc_clk>; |
| clock-names = "nand", "nand_x", "ecc"; |
| interrupts = <0 144 4>; |
| |
| nand@0 { |
| reg = <0>; |
| } |
| }; |
