treewide: Staticize and constify acpi ops

2026-06-29T21:29:44Z

Set the acpi_ops structure as static const where applicable. The The structure is not accessible from outside of drivers and is not going to be modified at runtime. The structure may be unused in a couple of drivers depending on their configuration, mark those sites with __maybe_unused . Signed-off-by: Marek Vasut Reviewed-by: Simon Glass

tpm: Make U_BOOT_DRIVER entries unique

2025-10-14T07:42:27Z

All instances of the U_BOOT_DRIVER must use a unique name or they will lead to link time failures due to name space conflicts when both are present. In this case the driver was reusing the tpm_tis_i2c name. Signed-off-by: Tom Rini Reviewed-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas

tpm: tis_infineon: Cannot test unsigned for being negative

2025-08-25T10:04:21Z

tpm_tis_i2c_get_burstcount returns a size_t but also returns -EBUSY if the TPM is surrently busy. As size_t is an unsigned type simply testing for < 0 will not work so change the test for being equal to -EBUSY which will work. Also remove the trivial comments. This issue was found by Smatch.

tpm: tpm_tis_infineon: Make use of 'z' for printing size_t

2025-08-25T10:04:21Z

When printing the contents of an size_t variable we need to use z prefix to the format character in order to get the correct format type depending on 32 or 64bit-ness. Signed-off-by: Tom Rini Reviewed-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas

tpm: sandbox: Support self-test continue in emulator

global: Add instead of long indirect include path

2025-05-29T14:29:16Z

In a number of cases we have C files which rely on a chain of indirect include paths to get to be included via . To facilitate cleaning up make this code directly include . Signed-off-by: Tom Rini

tpm: cr50: Support opening the TPM multiple times

2025-04-14T19:59:01Z

The tpm_auto_start() function is used in tests and assumes that it can open the TPM even if it is already open and a locality claimed. The cr50 driver does not use the common TPM2 TIS code so lacks a check for the is_open field of struct tpm_chip and in fact it doesn't use that struct. Add an equivalent check to cr50_i2c_open(). This fixes all init sequences on that TPM -- e.g 'tpm init && tpm init' or 'tpm autostart && tpm init' used to hang Signed-off-by: Simon Glass Reviewed-by: Ilias Apalodimas Signed-off-by: Ilias Apalodimas
