Revert "TPM: ACPI/PNP dependency removal"

config TCG_TIS

	tristate "TPM Interface Specification 1.2 Interface"

	depends on PNP

	---help---

	  If you have a TPM security chip that is compliant with the

	  TCG TIS 1.2 TPM specification say Yes and it will be accessible

	  from within Linux.  To compile this driver as a module, choose

	  M here; the module will be called tpm_tis.



config TCG_BIOS_LOG

	bool "TPM bios mesurement log"

	depends on X86

	select ACPI

	---help---

	  ACPI is required for access to bios measurements lists and therefore

	  to validate the PCR[0] value. So say Yes in case you want this

	  feature and, consequently, ACPI will be enabled.
