Hello
We are usinf am3352 with kenel 4.9.59 from TI SDK. We have include the sip TOM v2.0 device SLB9670.
It's working fine with OS.
Now we also need suppont in the u-boot.
I download another SDK verseion am335x-evm-linux-sdk-src-06.00.00.07.tar.xz, this u-boot version include the driver with SLB9670.
In our design, slb9670 is connect to SPI1[MCASP0_ACLKX,MCASP0_FSX,MCASP0_AXR0,MCASP0_AHCLKR]
I add the follow into dts.
spi1_pins_default: spi1_pins_default {
pinctrl-single,pins = <
0x190 (PIN_INPUT_PULLUP | MUX_MODE3) /* (A13) mcasp0_aclkx.mcasp0_aclkx */
0x194 (PIN_INPUT_PULLUP | MUX_MODE3) /* (B13) mcasp0_fsx.mcasp0_fsx */
0x198 (PIN_OUTPUT_PULLUP | MUX_MODE3) /* (D12) mcasp0_axr0.mcasp0_axr0 */
0x19c (PIN_OUTPUT_PULLUP | MUX_MODE3) /* (C12) mcasp0_ahclkr.mcasp0_axr2*/
>;
};
&spi1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi1_pins_default>;
ti,pindir-d0-out-d1-in;
slb9670@0 {
compatible = "tis,tpm2-spi";
reg = <0>;
spi-max-frequency = <12000000>;
};
};
When I running the "tpm init", I got following.
=> tpm init
