MT7986 series is Mediatek's new 4-core SoC, which is mainly for
wifi-router application. The difference between mt7986a and mt7986b
is that some pins do not exist on mt7986b.

Hi Sam,

I'd advise to split this series in parts for:
- basic device support via dts.
- pinctrl driver + dts
- clk driver + dts

I would also advise to not send new versions of patches as new threads and don't 
respond in the same thread. At least for me that breaks my workflow as I use b4.

Regards,
Matthias

Okay, I will split the patches that are still under review into the
above patch series.

But I have a dumb question, currently, we have some patches that have
been assigned version numbers.
If I want to seprate original patch series, and resend 3 new patch
series (basic / pinctrl / clock) according to your comment, if I want
to keep the preview change log, tags in the patch set: 

like:
---
v3: changed 'MT7986' to 'MT7986 series' in the commit message
v2: added an Acked-by tag
---

Which version number should I use for these new patch series ?

Does the version number in corver-letter and the version number in each
patch need to be the same in the entire patch series ?

// (Original patch series/thread, version number is v3)
[PATCH v3 0/3] Add basic SoC support for mediatek mt7986
  [PATCH v3 1/3] dt-bindings: arm64: dts: mediatek: Add mt7986 series
  // (the version number has been updated to v5 previously)
  // (basic part only, not include pinctrl and clock nodes)
  [PATCH v5 2/3] arm64: dts: mediatek: add mt7986a support
  [PATCH v5 3/3] arm64: dts: mediatek: add mt7986b support

// (New clock driver patch series)
[PATCH 0/3] Add clock driver support for mediatek mt7986
  [PATCH v3,1/3] dt-bindings: clock: mediatek: document clk bindings   
for mediatek mt7986 SoC
  // (the version number has been updated to v3 previously)
  [PATCH v3 2/3] clk: mediatek: add mt7986 clock IDs
  [PATCH v2 3/3] clk: mediatek: add mt7986 clock support

// (New pinctrl driver patch series)

  // (the version number has been updated to v6 previously)
  [PATCH v6 1/4] dt-bindings: pinctrl: update bindings for MT7986 SoC
  // (the version number has been updated to v2 previously)
  [PATCH v2 2/4] pinctrl: mediatek: add support for MT7986 SoC
  [PATCH 3/4] arm64: dts: mediatek: add mt7986a pinctrl support
  [PATCH 3/4] arm64: dts: mediatek: add mt7986b pinctrl support

If I don't respond to the next patch set in the same thread, should I
create an entire new patch series ?

For example, if I want to update PATCH 2/3 in the bellows patch series,
and my PATCH 1/3 has been accepted by reviewer previously

[PATCH v2 0/3] Add basic SoC support for mediatek mt7986
  [PATCH v2 1/3] ...   (patch set v1, applied by matainer)
  [PATCH v2 2/3] ...   (patch set v2, need to be upgrade to v3)
  [PATCH v2 3/3] ...   (patch set v1, waiting for review)

Is this correct to send patch mail to maintaiers for the above
situation ?

[PATCH v3 0/2] Add basic SoC support for mediatek mt7986
  [PATCH v3 1/2] ...   (patch set v3)
  [PATCH v3 2/2] ...   (still patch set v1, waiting for review)

I'd use v4 keeping the change-log and adding a link with hint to v3 in the cover 
letter.

Yes, otherwise the version number doesn't make to much sense.

use v6 explaining where in the mailing list one can find v5.

Same here, use v4.

use v7 here.

Respond to any review comments in the thread but once you are ready to send a 
new version of the patch, send the whole series with an incremented

beware: applied != accepted
reviewer != maintainer

if the patch got applied to some maintainer repo, then in the next version drop 
that patch (it is already applied) but mention that in the cover letter.

This series would be v3, if 1/3 is applied, drop. 2/3 will have changes and 3/3 
will be the same as in v2.

yes, that's how is expected you send your patches.

Let me know if you have any further questions :)
