You don't need a wrapper function for just a single clk_bulk_prepare_enable() call.

Same for this one....
... which means that this file will have only mt7986_init_clock() so, ultimately,
you don't need a mt7986-afe-clk.c file at all.
Please merge this logic into mt7986-afe-pcm.c, which is also the only user of it.
Thanks,
Angelo

OK, I'll use clk_bulk_prepare_enable directly.

Hi Angelo,
Thanks for your review.
I'll remove mt7986-afe-clk.c and merge related clock api to mt7986-afe-
pcm.c in v3 patch.

Hi Claudiu,
Thanks for your review.
This is for (IS_ERR(afe->regmap)) error handling.
May I just remove this one? or any other suggestion?

Fix the comment format please; for multi-line comments, you want:

As said in the review for patch [2/7], function mt7986_init_clock() must be moved
in this file instead.

That shall not be a dev_warn, but a dev_err() instead, but then, being this
a probe function and not needing that jump, it's dev_err_probe().

Same here.

You don't need this label because you're now using devm_pm_runtime_enable() and,
following my advice from some lines up, pm_runtime_put_sync() is called at the
right time already.
This means that you can simplify this function a lot with directly returning the
error in error paths (including instances of dev_err_probe() ).

You don't need the comma here ^^
so this is just
{ .compatible = "mediatek,mt7986-afe" },
Everything else looks fine.

Or is there any example for reference for this case?
Best regards,

Hi Rob,
Thanks for your review.
I'll refine as below in v3 patch.
items:
- const: bus_ck
- const: 26m_ck
- const: l_ck
- const: aud_ck
- const: eg2_ck
- const: sel
- const: i2s_m
And modify example as well.
Best regards,
Maso
