Hi, The following patchset: - 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: d4989d9f693b9502f9288da5db279c2f8c2e50be tpm/tpm_tis: Add missing ifdef CONFIG_ACPI for pnp_acpi_device I confirm also Jarkko Sakkinen's changes are working with this product with both phy's. - v2 takes into account feedbacks from Jason Gunthorpe. - v3 is reduced to 4 patches as 6 out of 10 got accepted for 3.20. Also compare to v2: * Fix build issue with patch v2 04/10 "Replace access to io_lpcpd from struct st33zp24_platform_data to tpm_stm_dev" * Fix link issue with patch v2 08/10 "Split tpm_i2c_tpm_st33 in 2 layers (core + phy)" when building as a module. The symbols wasn't exported in st33zp24.c. * Add missing MODULE_LICENSE in patch v2 09/10 "Add st33zp24 spi phy" * Fix node example in dts spi documentation in patch v2 10/10 "Add dts documentation for st33zp24 spi phy" * Fix typo on Jason Gunthorpe first name. Sorry for that :(... * Change contact email address as tpmsupport@xxxxxx is no more valid - v4 adds missing module_license in st33zp24 - v5 includes as best as possible PeterHuewe comments.
