See linux-yocto as an example. You need to name the two git uris:

SRC_URI = "\
git://git.yoctoproject.org/linux-yocto-a;protocol=git;name=machine \
git://git.yoctoproject.org/linux-yocto-b;protocol=git;name=meta \
"

set a format string to determine how the revisions should be placed in
SRCPV:

SRCREV_FORMAT = "meta_machine"

specify PV:

PV = "0.0+gitr${SRCPV}"

and then something like:

SRCREV_meta = "${AUTOREV}"
SRCREV_machine = "${AUTOREV}"

Cheers,
