Subject: [PATCH 57/91] 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";
