drivers: rename drivers to match compatible string

2020-07-10T00:57:22+00:00

When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

tpm: add #ifndef to fix redeclaration build errors

2020-07-08T21:21:46+00:00

tpm_tis_spi.c directly includes tpm_tis.h and tpm-v2.h which both
define the same enums (see e.g. TPM_ACCESS_VALID). Add an #ifndef to
prevent redeclaration errors.

tpm2: tis_spi: add linux compatible fallback string

2020-07-08T19:38:32+00:00

This solves a compatibility issue with Linux device trees
that contain TPMv2.x hardware. So it's easier to import DTS
from upstream kernel when migrating board init from C code
to DTS.

The issue is that fallback binding is different between Linux
and u-Boot.

Linux: "tcg,tpm_tis-spi"
U-Boot: "tis,tpm2-spi"

As there are currently no in-tree users of the U-Boot binding,
it makes sense to use Linux fallback binding.

tpm: Don't cleanup unless an error happens

2020-04-16T06:36:28+00:00

At present the cleanup() method is called on every transfer. It should
only be called on failing transfers. Fix this and tidy up the error
handling a little.

At present the cr50 driver claims the locality and does not release it for
Linux. This causes problems. Fix this by tracking what is claimed, and
adding a 'remove' method.
