tpm: st33zp24: switch to using gpiod API Switch the driver from legacy gpio API (that uses flat GPIO numbering) to the newer gpiod API (which used descriptors and respects line polarities specified in ACPI or device tree). Because gpio handling code for SPI and I2C variants duplicates each other it is moved into the core code for the driver. Also, it seems that the driver never assigned tpm_dev->io_lpcpd in the past, so gpio-based power management was most likely not working ever.

tpm: st33zp24: fix potential buffer overruns caused by bit glitches on the bus Discrete TPMs are often connected over slow serial buses which, on some platforms, can have glitches causing bit flips. In all the driver _recv() functions, we need to use a u32 to unmarshal the response size, otherwise a bit flip of the 31st bit would cause the expected variable to go negative, which would then try to read a huge amount of data. Also sanity check that the expected amount of data is large enough for the TPM header.

tpm: Factor out common startup code The TCG standard startup sequence (get timeouts, tpm startup, etc) for TPM and TPM2 chips is being open coded in many drivers, move it into the core code. tpm_tis and tpm_crb are used as the basis for the core code implementation and the easy drivers are converted. In the process several small drivers bugs relating to error handling this flow are fixed. For now the flag TPM_OPS_AUTO_STARTUP is optional to allow a staged driver roll out, but ultimately all drivers should use this flow and the flag removed. Some drivers still do not implement the startup sequence at all and will need to be tested with it enabled.
