vid pid isa device

We are trying to support development and validation of a tpm chip
(still being developed). A TPM chip is located on a LPC bus, which is
modified version of ISA bus and is like ISA bus as far as writing a
driver goes. We are going to write the drivers and other supporting
software for it. As an experiment we would like to use drivers for an
existing tpm chip. For example, we install the drivers for a Broadcom
tpm chip and then swap the Broadcom tpm chip with the chip being
developed. We are hoping to exercise some of the functionality with
this set up.
My question is – Does this make sense?
Also, As I understand, ISA( LPC ) devices don’t have Vendor ID, Device
ID but under DeviceManager under this driver I see something like the
following and was wondering what is their role?
Hardware Ids- ACPI\BCM0102 *BCM0102
Compatible Ids - *PNP0C31
