Further investigation finds Jassi did apply this and 3 other patches.
Stephen reported a conflict on 1/6 with another Qcom patch
(conflicting with Bjorn's tree). No reply to Stephen, but *all* the
mbox binding patches were dropped.

Here's what was dropped:

f8f632c18c32 dt-bindings: mbox: add pic64gx mailbox compatibility to
mpfs mailbox
945dc11a38a0 dt-bindings: mailbox: qcom: Add CPUCP mailbox controller
bindings for Kaanapali
66b6e5daa915 dt-bindings: mailbox: qcom: Add IPCC support for
Kaanapali and Glymur Platforms
9a92e22740e6 dt-bindings: mailbox: mediatek,mt8196-vcp-mbox: add mtk
vcp-mbox document
