The TPM driver depends on and takes advantage of the multi-stage OP-TEE bus enumeration by indicating that it should be probed after tee-supplicant has been started. Jarkko, one of the TPM maintainers, has been involved in reviewing these patches and agrees that I can include the TPM patch in the pull request. Thanks, Jens The following changes since commit 3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162: Linux 5.7 (2020-05-31 16:49:15 -0700) are available in the Git repository at: git://git.linaro.org/people/jens.wiklander/linux-tee.git tags/optee-bus-for= -v5.9 for you to fetch changes up to 9f1944c23c8cb1c033b73de80cf6c612a2a80a2b: tpm_ftpm_tee: register driver on TEE bus (2020-07-10 09:41:58 +0200) ---------------------------------------------------------------- Enable multi-stage OP-TEE bus enumeration Probes drivers on the OP-TEE bus in two steps. First for drivers which do not depend on tee-supplicant. After tee-supplicant has been started probe the devices which do depend on tee-supplicant. Also introduces driver which uses an OP-TEE based fTPM Trusted Application depends on tee-supplicant NV RAM implementation based on RPMB secure storage. ---------------------------------------------------------------- Maxim Uvarov (3): optee: use uuid for sysfs driver entry optee: enable support for multi-stage bus enumeration tpm_ftpm_tee: register driver on TEE bus Documentation/ABI/testing/sysfs-bus-optee-devices | 8 +++ MAINTAINERS | 1 + drivers/char/tpm/tpm_ftpm_tee.c | 70 +++++++++++++++++++--= -- drivers/tee/optee/core.c | 27 ++++++++- drivers/tee/optee/device.c | 38 ++++++------ drivers/tee/optee/optee_private.h | 10 +++- 6 files changed, 119 insertions(+), 35 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-optee-devices --===============1386209375389558978==--
