- Subject: [PATCH 57/81] mtd: mediatek: device tree docs for MTK Smart Device
- Gen1 NAND
- This patch adds documentation support for Smart Device Gen1 type of
- NAND controllers.
- Mediatek's SoC 2701 is one of the SoCs that implements this controller.

- +MTK Smart Device SoCs NAND controller DT binding
- +
- +Required properties:
- +- compatible: Should be "mediatek,mt2701-nfc".
- +- reg: The first contains base physical address and size of
- + NAND controller's registers. The second contains base
- + physical address and size of NAND ECC engine.
- +- interrupts: the NFC NFI interrupt, and the NFC ECC interrupt
- +- clocks: NAND controller clocks.
- +- clock-names: NAND controller clocks internal name.
- +- vmch-supply: NAND power supply.
- +- #address-cells: Partition address, should be set 1.
- +- #size-cells: Partition size, should be set 1.
- +
- +Optional properties:
- +
- +nand-on-flash-bbt: Use a flash based bad block table.
- +
- +Optional subnodes:
- +- Partitions, see Documentation/devicetree/bindings/mtd/partition.txt
- +
- +Example:
- +
- + nand: nand@1100d000 {
- + compatible = "mediatek,mt2701-nfc";
- + reg = <0 0x1100d000 0 0x1000>, <0 0x1100e000 0 0x1000>;
- + interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_LOW>,
- + <GIC_SPI 55 IRQ_TYPE_LEVEL_LOW>;
- + clocks = <&pericfg CLK_PERI_NFI>, <&pericfg CLK_PERI_NFI_ECC>,
- + <&pericfg CLK_PERI_NFI_PAD>;
- + clock-names = "nfi_ck", "nfi_ecc_ck", "nfi_pad_ck";
- + vmch-supply = <&mt6323_vmch_reg>;
- + status = "disabled";
- + #address-cells = <1>;
- + #size-cells = <1>;
- +
- + ...
