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@st.com is no more valid
- v4 adds missing module_license in st33zp24
- v5 includes as best as possible PeterHuewe comments.

Best Regards
Christophe
