The mbox name has to align with the adsp ipc driver.
The adsp ipc driver is using 'mbox%d' for mailbox channels.
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/commit/?id=9db69df4bdd37eb1f65b6931ee067fb15b9a4d5c
chan_name = kasprintf(GFP_KERNEL, "mbox%d", i);
/* ...snip... */
adsp_chan->ch = mbox_request_channel_byname(cl, chan_name);
Is it ok to continue using these names?

The mbox name has to align with the adsp ipc driver.
The adsp ipc driver is using 'mbox%d' for mailbox channels.
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/commit/?id=9db69df4bdd37eb1f65b6931ee067fb15b9a4d5c
chan_name = kasprintf(GFP_KERNEL, "mbox%d", i);
/* ...snip... */
adsp_chan->ch = mbox_request_channel_byname(cl, chan_name);
Is it ok to continue using these names?

It is a bit confusing... how did that driver got merged recently without
bindings? Why bindings are separate?
The bindings always come together in one patchset with the driver
implementing them. Bindings are though a separate patch, yet still
followed by the driver which uses them.
I do not see any compatibles in that driver, which suggests there is no
other binding using it. If that's correct, then you need to change the
driver.
Best regards,
Krzysztof

The mtk-adsp-ipc driver's sole function is to encapsulate the operations
of mailbox framework from adsp ipc users. The mtk-adsp-ipc is not defined
in the dts file and we don't need it to be defined. The creation of mtk-adsp-ipc
device is requested by adsp ipc users via the use of 'platform_device_register_data'[1].
the driver implemented the mailbox framework is 'mtk-adsp-mailbox'[2]. it has
corresponding hardwares and a yaml file[3] to describe it.
I'll send a patch to change the mbox name at next version.
It's better to have some meaningful names as you said.

I don't understand how is this related. We talk here about the
mbox-names for this bindings file. You replied, that these bindings are
already used by something, but now you say that they are not? So why do
you need to change anything in any driver?
Simple question - do the bindings here "add mt8186 dsp document" are
used by any specific Linux driver already?

This bindings, 'add mt8186 dsp document', are used by the SOF sound driver of MT8186[1].
I'm sorry for miss leading you in previous reply. I was thought that you're
asking why the mtk-adsp-ipc driver got merged without bindings. So, I tried
to explain why mtk-adsp-ipc doesn't have bindings.

Then my question is kind of still valid:
How did "mt8186 SOF" driver got merged recently without bindings? Why
bindings are separate?
You cannot just sneak in usage of bindings in a driver, then submit
bindings and say "we already have an user!". No, the bindings come with
the driver. Always.
Linked patch [1] brings undocumented compatible mediatek,mt8186-dsp, so
you should see big fat warning when running checkpatch. So this points
that you did not run checkpatch which is another not acceptable
submission. :(

Then my question is kind of still valid:
How did "mt8186 SOF" driver got merged recently without bindings? Why
bindings are separate?
You cannot just sneak in usage of bindings in a driver, then submit
bindings and say "we already have an user!". No, the bindings come with
the driver. Always.
Linked patch [1] brings undocumented compatible mediatek,mt8186-dsp, so
you should see big fat warning when running checkpatch. So this points
that you did not run checkpatch which is another not acceptable
submission. :(

I apologize for breaking the rules and sending inappropriate patches.
I was thought that it was acceptable to send community reviewed patches in a series,
then followed the bindings at another patch. I was believed that separating un-reviewed
binding patch from reviewed driver patches would aid in patch acceptance.
Now, I see I make a big mistake. I'm sorry.
