When I try building with `make run WITH_SCMI=y` then the build fails: core/lib/scmi-server/scmi_server.c: In function ‘scmi_server_initialize’: core/lib/scmi-server/scmi_server.c:83:22: error: implicit declaration of function ‘scmi_configure’ [-Wimplicit-function-declaration] 83 | rc = scmi_configure(cfg); | ^~~~~~~~~~~~~~ This was introduced in commit ce6ea4112008 ("scmi-server: configure SCP-firmware from DT"). A grep for scmi_configure() turns up empty. Was part of the commit missing? regards, dan carpenter

[PATCH v1 00/17] tee: Use bus callbacks instead of driver callbacks

by Uwe Kleine-König

Hello, the objective of this series is to make tee driver stop using callbacks in struct device_driver. These were superseded by bus methods in 2006 (commit 594c8281f905 ("[PATCH] Add bus_type probe, remove, shutdown methods.")) but nobody cared to convert all subsystems accordingly. Here the tee drivers are converted. The first commit is somewhat unrelated, but simplifies the conversion (and the drivers). It introduces driver registration helpers that care about setting the bus and owner. (The latter is missing in all drivers, so by using these helpers the drivers become more correct.) The patches #4 - #17 depend on the first two, so if they should be applied to their respective subsystem trees these must contain the first two patches first. Note that after patch #2 is applied, unconverted drivers provoke a warning in driver_register(), so it would be good for the user experience if the whole series goes in during a single merge window. So I guess an immutable branch containing the frist three patches that can be merged into the other subsystem trees would be sensible. After all patches are applied, tee_bus_type can be made private to drivers/tee as it's not used in other places any more. Best regards Uwe Uwe Kleine-König (17): tee: Add some helpers to reduce boilerplate for tee client drivers tee: Add probe, remove and shutdown bus callbacks to tee_client_driver tee: Adapt documentation to cover recent additions hwrng: optee - Make use of module_tee_client_driver() hwrng: optee - Make use of tee bus methods rtc: optee: Migrate to use tee specific driver registration function rtc: optee: Make use of tee bus methods efi: stmm: Make use of module_tee_client_driver() efi: stmm: Make use of tee bus methods firmware: arm_scmi: optee: Make use of module_tee_client_driver() firmware: arm_scmi: Make use of tee bus methods firmware: tee_bnxt: Make use of module_tee_client_driver() firmware: tee_bnxt: Make use of tee bus methods KEYS: trusted: Migrate to use tee specific driver registration function KEYS: trusted: Make use of tee bus methods tpm/tpm_ftpm_tee: Make use of tee specific driver registration tpm/tpm_ftpm_tee: Make use of tee bus methods Documentation/driver-api/tee.rst | 18 +---- drivers/char/hw_random/optee-rng.c | 26 ++---- drivers/char/tpm/tpm_ftpm_tee.c | 31 +++++--- drivers/firmware/arm_scmi/transports/optee.c | 32 +++----- drivers/firmware/broadcom/tee_bnxt_fw.c | 30 ++----- drivers/firmware/efi/stmm/tee_stmm_efi.c | 25 ++---- drivers/rtc/rtc-optee.c | 27 ++----- drivers/tee/tee_core.c | 84 ++++++++++++++++++++ include/linux/tee_drv.h | 12 +++ security/keys/trusted-keys/trusted_tee.c | 17 ++-- 10 files changed, 164 insertions(+), 138 deletions(-) base-commit: 7d0a66e4bb9081d75c82ec4957c50034cb0ea449 -- 2.47.3
