Hi, The following patchset: - clean the current tpm_i2c_stm_st33 driver - propose a new architecture allowing to share a core st33zp24 data management layer with different phy (i2c & spi). For st33zp24 both phy have a proprietary transport protocol. Both are relying on the TCG TIS protocol. At the end, it simplifies the maintenance. - Add an spi phy allowing to support st33zp24 using with an SPI bus. The complete solution got tested in polling and interrupt mode successfully with i2c & spi phy. This patchset applies on top of Peter's tree https://github.com/PeterHuewe/linux-tpmdd.git for-james branch on top of: tpm: TPM 2.0 FIFO Interface 2c71d9fb22289a196a4b51d6158cf0d2f9abcfb9 I confirm also Jarkko Sakkinen's changes are working with this product with both phy's. v2 takes into account feedbacks from Jason Gunthorpe.
