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>;
