I forgot to sort nodes in my previous mail. Sorry for the inconvenience.
This patch depends on the series: https://lkml.org/lkml/2018/9/5/223
@Matthias,
I know you're working on broken MMSYS - just want to ask whether it's possible
to let the patch to go to your tree (if others are okay with it), and send a
fixup one for MT7623 MMSYS later?

I fallback to use the MT2701's compatible string here and there, but I
could add a new one for MT7623.
BTW, I've had this question for a long time - should I add a new
compatible for the very same IPs, or could we just use the old one in
DTS?

>From [1], there is a description for the multiple compatible string
scheme:
====
The reasoning behind this scheme is the observation that in the majority
of cases, a single machine_desc can support a large number of boards
if they all use the same SoC, or same family of SoCs. However,
invariably there will be some exceptions where a specific board will
require special setup code that is not useful in the generic case.
Special cases could be handled by explicitly checking for the
troublesome board(s) in generic setup code, but doing so very quickly
becomes ugly and/or unmaintainable if it is more than just a couple of
cases.
Instead, the compatible list allows a generic machine_desc to provide
support for a wide common set of boards by specifying "less
compatible" values in the dt_compat list. In the example above,
generic board support can claim compatibility with "ti,omap3" or
"ti,omap3450". If a bug was discovered on the original beagleboard
that required special workaround code during early boot, then a new
machine_desc could be added which implements the workarounds and only
matches on "ti,omap3-beagleboard".
====
I don't know would there be a problem happened only in MT7623 even
though this hardware is identical in both MT2701 and MT7623. Maybe the
system-wide configuration would influence this driver. So the easy way
is to add the compatible string for MT7623. If you could prove that
this driver would never be influenced by system-wide configuration,
using only MT2701 compatible string is acceptable for me.
This is my opinion, but the most important is maintainer's opinion.

From [1], there is a description for the multiple compatible string
scheme:
====
The reasoning behind this scheme is the observation that in the majority
of cases, a single machine_desc can support a large number of boards
if they all use the same SoC, or same family of SoCs. However,
invariably there will be some exceptions where a specific board will
require special setup code that is not useful in the generic case.
Special cases could be handled by explicitly checking for the
troublesome board(s) in generic setup code, but doing so very quickly
becomes ugly and/or unmaintainable if it is more than just a couple of
cases.
Instead, the compatible list allows a generic machine_desc to provide
support for a wide common set of boards by specifying "less
compatible" values in the dt_compat list. In the example above,
generic board support can claim compatibility with "ti,omap3" or
"ti,omap3450". If a bug was discovered on the original beagleboard
that required special workaround code during early boot, then a new
machine_desc could be added which implements the workarounds and only
matches on "ti,omap3-beagleboard".
====
I don't know would there be a problem happened only in MT7623 even
though this hardware is identical in both MT2701 and MT7623. Maybe the
system-wide configuration would influence this driver. So the easy way
is to add the compatible string for MT7623. If you could prove that
this driver would never be influenced by system-wide configuration,
using only MT2701 compatible string is acceptable for me.
This is my opinion, but the most important is maintainer's opinion.

The compatible string looks good. But you should update the binding documentation :)
