+Subject: [PATCH 57/78] 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>;
