tpm: add support for TPMv2.x I2C chips

2022-05-23T13:33:58Z

Add the tpm2_tis_i2c driver that should support any TPMv2 compliant I2C chips, such as the NPCT75X chip. [Ilias rename priv_auto_alloc_size to priv_auto] Signed-off-by: Eddie James Reviewed-by: Joel Stanley Reviewed-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas

tpm: core: Set timeouts before requesting locality

2022-05-23T13:32:55Z

Requesting the locality uses the timeout values, so they need to be set beforehand. Signed-off-by: Eddie James Reviewed-by: Ilias Apalodimas Reviewed-by: Joel Stanley Signed-off-by: Ilias Apalodimas

tis: fix tpm_tis_remove()

2021-11-30T12:11:05Z

tpm_tis_remove() leads to calling tpm_tis_ready() with the IO region unmapped and chip->locality == -1 (locality released). This leads to a crash in mmio_write_bytes(). The patch implements these changes: tpm_tis_remove(): Unmap the IO region after calling tpm_tis_cleanup(). tpm_tis_cleanup(): Request locality before IO output and releasing locality.

drivers: tpm: atmel_twi: implement get_desc operation

2021-11-17T11:47:33Z

Without get_desc, the tpm command will not provide a description of the device in 'tpm device' or 'tpm info'. Due to the characteristics of the Atmel TPM it isn't possible to determine certain attributes (e.g open/close status) without using the TPM stack (compare Infineon and ST TPM drivers), so just print out the chip model and udevice name as the identifier.

drivers: tpm: atmel_twi: do not use an offset byte

2021-11-17T11:47:31Z

This driver was broken due to an empty offset byte being prepended at the start of every transmission. The hardware does not mimic an EEPROM device with registers so an offset byte is not required. Signed-off-by: Mathew McBride Acked-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas
