Cover letter [PATCH 0/2] tee: optee: report OP-TEE revision information

Hi,

This patchset updates the OP-TEE driver to report the version of the secure OS upon initialization. To further facilitate troubleshooting, an optional build ID is introduced in the response to the OPTEE_SMC_CALL_GET_OS_REVISION request. Upstream OP-TEE uses this field to report its Git SHA1 since commit 29cff5cf09aa ("core: GET_OS_REVISION:
return SHA1 of current Git commit").

Typical boot log (>> is introduced by this patchset):

optee: probing for conduit method from DT.

Quoted 1 line
Quoted 1 line

optee: revision 2.6 (947cfeec)

optee: initialized driver

...or, if the build ID is not set by the TEE or set to zero:

optee: probing for conduit method from DT.

Quoted 1 line
Quoted 1 line

optee: revision 2.6

optee: initialized driver
