Hi Martin,
Nevertheless one question: Why did you define another dts binding instead of using that one what is already available on the Linux kernel? There is "tcg,tpm_tis-spi" already defined.
I did not know this one, actually I mostly worked on U-Boot.
However, this compatible is misleading as it does not make any difference between v1.x and v2.0 specification.
But on the other hand it would give us a chance to determine the version at runtime what could be beneficial for firmware updates. But this is a special case.
We already discussed that point on the ML and decided to choose the version at compile time. I did not have the firmware update case in mind though.
Regards, Miquèl
