Rockchip NAND Flash Controller DT binding
Required properties:
- compatible : "rockchip,rk-nand-v9".
- reg : shall contain registers location and length for data and reg.
- interrupts : shall define the nand controller interrupt.
- clocks : shall reference nand controller clocks.
- clock-names : nand controller internal clock names. Shall contain :
* "hclk_nandc" : AHB gating clock
* "clk_nandc" : nand controller clock
Example for rk3326 / rkpx30:
nandc0: nandc@ff3b0000 {
compatible = "rockchip,rk-nandc-v9";
reg = <0x0 0xff3b0000 0x0 0x4000>;
interrupts = <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>;
nandc_id = <0>;
clocks = <&cru SCLK_NANDC>, <&cru HCLK_NANDC>;
clock-names = "clk_nandc", "hclk_nandc";
assigned-clocks = <&cru SCLK_NANDC>;
assigned-clock-parents = <&cru SCLK_NANDC_DIV50>;
clock-frequency = <150000000>;
status = "okay";
#address-cells = <1>;
#size-cells = <1>;
nand@0 {
reg = <0>;
nand-ecc-mode = "hw";
nand-ecc-strength = <16>;
nand-ecc-step-size = <1024>;
};
};
