2018-05-13drivers/pc80/tpm: get ioport from pnp recordsKevin Cody-Little
Had 0x2e hardcoded, which is often the SuperIO chip. Instead, pull the port from the PNP tree generated from devicetree.cb, where either 0x4e or 0x2e will be specified.

2018-04-16drivers/pc80/tpm: Add some optional delay to tis_readresponse()Bill XIE
Certain TPMs (observed on Infineon SLB9635 installed on revolve 810 g1) seem to need some delay between tis_wait_valid() and tis_has_valid_data(), or tis_has_valid_data() may invalidly return 0, ending the loop immaturely with some bytes left unread, and fail to pass the check below, causing the current command not finalized by tis_command_ready(), and blocking any later tis_wait_ready(). This time the added delay is controlled by a Kconfig option TPM_RDRESP_NEED_DELAY.
