Subject: [GIT PULL] TEE bus callbacks for 6.20

Hello arm-soc maintainers,

Please pull these updates adding TEE bus callbacks to let the users of
the bus get rid of the struct device_driver callbacks .probe(),
.remove() and .shutdown().

The maintainers for the updated drivers using the TEE bus have agreed to
take these changes via my tree, with the exception of the maintainer for
drivers/firmware/broadcom/tee_bnxt_fw.c, who has remained silent during
the review. However, the changes in the drivers are straight forward so
it's better to take these patches too rather than excluding them.

Further details are in the last patch set:

Thanks,
Jens
