[PATCH] tpm_infineon: Support for new TPM 1.2 and PNPACPI
This patch includes support for the new Infineon Trusted Platform Module SLB 9635 TT 1.2 and does further include ACPI-support for both chip versions (SLD 9630 TT 1.1 and SLB9635 TT 1.2). Since the ioports and configuration registers are not correctly set on some machines, the configuration is now done via PNPACPI, which reads out the correct values out of the DSDT-table. Note that you have to have CONFIG_PNP, CONFIG_ACPI_BUS and CONFIG_PNPACPI enabled to run this driver (assuming that mainboards including a TPM do have the need for ACPI anyway).
