    driver: add PPI support in tpm driver · f84fdff0
    Xiaoyan Zhang authored
    The Physical Presence Interface enables the OS and the BIOS to cooperate and
    provides a simple and straightforward platform user experience for
    administering the TPM without sacrificing security.
    
    V2: separate the patch out in a separate source file,
        add #ifdef CONFIG_ACPI so it compiles out on ppc,
        use standard error instead of ACPI error as return code of show/store fns.
    V3: move #ifdef CONFIG_ACPI from .c file to .h file.
    V4: move tpm_ppi code from tpm module to tpm_bios module.
    V5: modify sys_add_ppi() so that ppi_attr_grp doesn't need to be exported
