Yes, these related files are in the different maintainer's tree.
Refer to https://www.kernel.org/doc/linux/MAINTAINERS

MAILBOX API
M: Jassi Brar
F: drivers/mailbox/
- drivers/mailbox/mtk-cmdq-mailbox.c
- drivers/mailbox/mtk-cmdq-sec-
mailbox.c

ARM/Mediatek SoC support
M: Matthias Brugger
F: drivers/soc/mediatek/
K: mediatek
- drivers/soc/mediatek/mtk-cmdq-helper.c
-
include/linux/soc/mediatek/mtk-cmdq.h

I think we should add a new MAINTAINER label for mediatek CMDQ mailbox
and put these files together, such as "MAILBOX ARM MHUv2" and "QUALCOM
IPCC MAILBOX DRIVER".
But I don't know how to make a request for that.

Anyway, I'll squash this logical feature to the same patch, no matter
these files are not in the same tree.
