Allwinner NAND Flash Controller (NFC) Required properties: - compatible : "allwinner,sun4i-a10-nand". - reg : shall contain registers location and length for data and reg. - interrupts : shall define the nand controller interrupt. - #address-cells: shall be set to 1. Encode the nand CS. - #size-cells : shall be set to 0. - clocks : shall reference nand controller clocks. - clock-names : nand controller internal clock names. Shall contain : * "ahb" : AHB gating clock * "mod" : nand controller clock Optional properties: - dmas : shall reference DMA channel associated to the NAND controller. - dma-names : shall be "rxtx". Optional children nodes: Children nodes represent the available nand chips. Optional properties: - reset : phandle + reset specifier pair - reset-names : must contain "ahb" - allwinner,rb : shall contain the native Ready/Busy ids. - nand-ecc-mode : one of the supported ECC modes ("hw", "soft", "soft_bch" or "none") see Documentation/devicetree/bindings/mtd/nand.txt for generic bindings. Examples: nfc: nand@1c03000 { compatible = "allwinner,sun4i-a10-nand"; reg = <0x01c03000 0x1000>; interrupts = <0 37 1>; clocks = <&ahb_gates 13>, <&nand_clk>; clock-names = "ahb", "mod"; #address-cells = <1>; #size-cells = <0>; pinctrl-names = "default"; pinctrl-0 = <&nand_pins_a &nand_cs0_pins_a &nand_rb0_pins_a>; nand@0 { reg = <0>; allwinner,rb = <0>; nand-ecc-mode = "soft_bch"; }; };
