-Freescale's NAND flash controller (NFC)
-
-This variant of the Freescale NAND flash controller (NFC) can be found on
-Vybrid (vf610), MPC5125, MCF54418 and Kinetis K70.
-
-Required properties:
-- compatible: Should be set to "fsl,vf610-nfc".
-- reg: address range of the NFC.
-- interrupts: interrupt of the NFC.
-- #address-cells: shall be set to 1. Encode the nand CS.
-- #size-cells : shall be set to 0.
-- assigned-clocks: main clock from the SoC, for Vybrid <&clks VF610_CLK_NFC>;
-- assigned-clock-rates: The NAND bus timing is derived from this clock
- rate and should not exceed maximum timing for any NAND memory chip
- in a board stuffing. Typical NAND memory timings derived from this
- clock are found in the SoC hardware reference manual. Furthermore,
- there might be restrictions on maximum rates when using hardware ECC.
-
-- #address-cells, #size-cells : Must be present if the device has sub-nodes
- representing partitions.
-
-Required children nodes:
-Children nodes represent the available nand chips. Currently the driver can
-only handle one NAND chip.
-
-Required properties:
-- compatible: Should be set to "fsl,vf610-nfc-cs".
-- nand-bus-width: see nand-controller.yaml
-- nand-ecc-mode: see nand-controller.yaml
-
-Required properties for hardware ECC:
-- nand-ecc-strength: supported strengths are 24 and 32 bit (see nand-controller.yaml)
-- nand-ecc-step-size: step size equals page size, currently only 2k pages are
- supported
-- nand-on-flash-bbt: see nand-controller.yaml
-
-Example:
-
- nfc: nand@400e0000 {
- compatible = "fsl,vf610-nfc";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x400e0000 0x4000>;
- interrupts = <GIC_SPI 83 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks VF610_CLK_NFC>;
- clock-names = "nfc";
- assigned-clocks = <&clks VF610_CLK_NFC>;
- assigned-clock-rates = <33000000>;
-
- nand@0 {
- compatible = "fsl,vf610-nfc-nandcs";
- reg = <0>;
- nand-bus-width = <8>;
- nand-ecc-mode = "hw";
- nand-ecc-strength = <32>;
- nand-ecc-step-size = <2048>;
- nand-on-flash-bbt;
- };
