Hi,

I modprobe TPM driver: tpm_tis_spi.

but get the error message:

 

and I modified the device tree file ls1043a-rdb.dts for dspi  as following:

......

&dspi0 {
bus-num = <1>;
status = "okay";

flash@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "n25q128a13", "jedec,spi-nor"; // 16MB /
reg = <0>;
spi-max-frequency = <1000000>; // input clock /
};

tcg@1 {
compatible = "tcg,tpm_tis-spi";
reg = <1>;
#address-cells = <1>;
#size-cells = <0>;
spi-max-frequency = <500000>;
pinctrl-names = "default";

};

...

Please help.

Thanks,

Randy
