to configure a ecspi node to fsl-imx8mq.dtsi , i added below.
Actually i, excerpted these from fsl-imx8mm.dtsi.
ecspi1: ecspi@30820000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,imx8mm-ecspi", "fsl,imx51-ecspi";
reg = <0x0 0x30820000 0x0 0x10000>;
interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk IMX8MM_CLK_ECSPI1_ROOT>,
<&clk IMX8MM_CLK_ECSPI1_ROOT>;
clock-names = "ipg", "per";
dmas = <&sdma1 0 7 1>, <&sdma1 1 7 2>;
dma-names = "rx", "tx";
status = "disabled";
};
ecspi2: ecspi@30830000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,imx8mq-ecspi", "fsl,imx51-ecspi";
reg = <0x0 0x30830000 0x0 0x10000>;
interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk IMX8MQ_CLK_ECSPI2_ROOT>,
<&clk IMX8MQ_CLK_ECSPI2_ROOT>;
clock-names = "ipg", "per";
dmas = <&sdma1 2 7 1>, <&sdma1 3 7 2>;
dma-names = "rx", "tx";
status = "disabled";
};
/*cause there is no sdma configuration to ecspi3 */
ecspi3: ecspi@30840000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,imx8mq-ecspi", "fsl,imx51-ecspi";
reg = <0x0 0x30840000 0x0 0x10000>;
interrupts = <GIC_SPI 33 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk IMX8MQ_CLK_ECSPI3_ROOT>,
<&clk IMX8MQ_CLK_ECSPI3_ROOT>;
clock-names = "ipg", "per";
/**
dmas = <&sdma1 4 7 1>, <&sdma1 5 7 2>;
dma-names = "rx", "tx";
***/
status = "disabled";
};
Can you check?
Thanks
