Hi All,

 

I am using IMX6q custom board, where I have to add max14830 SPI to quad uart device

for that I have added an entry in my device tree for max14830 as below:

 

&ecspi1 {

        fsl,spi-num-chipselects = <1>;

        cs-gpios = <&gpio4 9 0>;

        pinctrl-names = "default";

        pinctrl-0 = <&pinctrl_ecspi1_2>;

        status = "okay";

 

        max148300: max14830@0 {

                   compatible = "maxim,max14830";

                   reg = <0>;

                   clocks = <&xtal_max>;

                   clock-names = "xtal";

                   spi-max-frequency = <10000000>;

           };

&iomuxc

{

MX6QDL_PAD_KEY_ROW1__GPIO4_IO09  0x1b0b0;

};

 

and I load the driver max310x.ko, it gives me an error max14830 ID 0x00 does not match.

Can anybody help me where I am going wrong?

 

TIA,

Arti.
