Subject[GIT PULL] OP-TEE FF-A for V5.16
Hello arm-soc maintainers,

Please pull these patches which adds support for FF-A [1] in the OP-TEE
driver. There's a bit of shuffling in the code where everyhting related to
the old SMC based ABI is moved to drivers/tee/optee/smc_abi.c, but there
should not be any changed in behavior for with the old ABI.

Note that this is based on top of the recent fix 7f565d0ead26 ("tee: optee:
Fix missing devices unregister during optee_remove") which has already been
requested to be pulled.

Thanks,
Jens
