|
|
|
|
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"
|
|
- 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"
|
|
|
|
Optional properties:
|
|
- nand-ecc-step-size: see nand.txt 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.txt 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.txt for details
|
|
|
|
The device tree may optionally contain sub-nodes describing partitions of the
|
|
address space. See partition.txt for more detail.

|
|
|
|
nand: nand@ff900000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
