-MTK SoCs NAND FLASH controller (NFC) DT binding
-
-This file documents the device tree bindings for MTK SoCs NAND controllers.
-The functional split of the controller requires two drivers to operate:
-the nand controller interface driver and the ECC engine driver.
-
-The hardware description for both devices must be captured as device
-tree nodes.
-
-1) NFC NAND Controller Interface (NFI):
-=======================================
-
-The first part of NFC is NAND Controller Interface (NFI) HW.
-Required NFI properties:
-- compatible: Should be one of
- "mediatek,mt2701-nfc",
- "mediatek,mt2712-nfc",
- "mediatek,mt7622-nfc".
-- reg: Base physical address and size of NFI.
-- interrupts: Interrupts of NFI.
-- clocks: NFI required clocks.
-- clock-names: NFI clocks internal name.
-- ecc-engine: Required ECC Engine node.
-- #address-cells: NAND chip index, should be 1.
-- #size-cells: Should be 0.
-
-Example:
-
- nandc: nfi@1100d000 {
- compatible = "mediatek,mt2701-nfc";
- reg = <0 0x1100d000 0 0x1000>;
- interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_LOW>;
- clocks = <&pericfg CLK_PERI_NFI>,
- <&pericfg CLK_PERI_NFI_PAD>;
- clock-names = "nfi_clk", "pad_clk";
- ecc-engine = <&bch>;
- #address-cells = <1>;
- #size-cells = <0>;
- };
-
-Platform related properties, should be set in {platform_name}.dts:
-- children nodes: NAND chips.
-
-Children nodes properties:
-- reg: Chip Select Signal, default 0.
- Set as reg = <0>, <1> when need 2 CS.
-Optional:
-- nand-on-flash-bbt: Store BBT on NAND Flash.
-- nand-ecc-mode: the NAND ecc mode (check driver for supported modes)
-- nand-ecc-step-size: Number of data bytes covered by a single ECC step.
- valid values:
- 512 and 1024 on mt2701 and mt2712.
- 512 only on mt7622.
- 1024 is recommended for large page NANDs.
-- nand-ecc-strength: Number of bits to correct per ECC step.
- The valid values that each controller supports:
- mt2701: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28,
- 32, 36, 40, 44, 48, 52, 56, 60.
- mt2712: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28,
- 32, 36, 40, 44, 48, 52, 56, 60, 68, 72, 80.
- mt7622: 4, 6, 8, 10, 12, 14, 16.
- The strength should be calculated as follows:
- E = (S - F) * 8 / B
- S = O / (P / Q)
- E : nand-ecc-strength.
- S : spare size per sector.
- F : FDM size, should be in the range [1,8].
- It is used to store free oob data.
- O : oob size.
- P : page size.
- Q : nand-ecc-step-size.
- B : number of parity bits needed to correct
- 1 bitflip.
- According to MTK NAND controller design,
- this number depends on max ecc step size
- that MTK NAND controller supports.
- If max ecc step size supported is 1024,
- then it should be always 14. And if max
- ecc step size is 512, then it should be
- always 13.
- If the result does not match any one of the listed
- choices above, please select the smaller valid value from
- the list.
- (otherwise the driver will do the adjustment at runtime)
-- pinctrl-names: Default NAND pin GPIO setting name.
-- pinctrl-0: GPIO setting node.
-
-Example:
- &pio {
- nand_pins_default: nanddefault {
- pins_dat {
- pinmux = <MT2701_PIN_111_MSDC0_DAT7__FUNC_NLD7>,

-NAND chip optional subnodes:
-- Partitions, see Documentation/devicetree/bindings/mtd/mtd.yaml

-Example:

- partitions {

- #address-cells = <1>;
- #size-cells = <1>;
-
- preloader@0 {
- label = "pl";

- android@00400000 {
- label = "android";
- reg = <0x00400000 0x12c00000>;
- };
- };
- };
-
-2) ECC Engine:
-==============
-
-Required BCH properties:
-- compatible: Should be one of
- "mediatek,mt2701-ecc",
- "mediatek,mt2712-ecc",
- "mediatek,mt7622-ecc".
-- reg: Base physical address and size of ECC.
-- interrupts: Interrupts of ECC.
-- clocks: ECC required clocks.
-- clock-names: ECC clocks internal name.
-
-Example:
-
- bch: ecc@1100e000 {
- compatible = "mediatek,mt2701-ecc";
- reg = <0 0x1100e000 0 0x1000>;
- interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_LOW>;
- clocks = <&pericfg CLK_PERI_NFI_ECC>;
- clock-names = "nfiecc_clk";
