1* Denali NAND controller
2
3Required properties:
4  - compatible : should be one of the following:
5      "altr,socfpga-denali-nand"            - for Altera SOCFPGA
6      "socionext,uniphier-denali-nand-v5a"  - for Socionext UniPhier (v5a)
7      "socionext,uniphier-denali-nand-v5b"  - for Socionext UniPhier (v5b)
8  - reg : should contain registers location and length for data and reg.
9  - reg-names: Should contain the reg names "nand_data" and "denali_reg"
10  - interrupts : The interrupt number.
11  - clocks: should contain phandle of the controller core clock, the bus
12    interface clock, and the ECC circuit clock.
13  - clock-names: should contain "nand", "nand_x", "ecc"
14
15Optional properties:
16  - nand-ecc-step-size: see nand.txt for details.  If present, the value must be
17      512        for "altr,socfpga-denali-nand"
18      1024       for "socionext,uniphier-denali-nand-v5a"
19      1024       for "socionext,uniphier-denali-nand-v5b"
20  - nand-ecc-strength: see nand.txt for details.  Valid values are:
21      8, 15      for "altr,socfpga-denali-nand"
22      8, 16, 24  for "socionext,uniphier-denali-nand-v5a"
23      8, 16      for "socionext,uniphier-denali-nand-v5b"
24  - nand-ecc-maximize: see nand.txt for details
25
26The device tree may optionally contain sub-nodes describing partitions of the
27address space. See partition.txt for more detail.
