[PATCH 0/4] MediaTek MT6735 pinctrl support and DT binding changes

[Yassine Oudjana]

From: Yassine Oudjana <y.oudjana@protonmail.com>

This series adds a driver for the pin controller found on the MediaTek MT6735
and MT6735M SoCs. The two differ in the last 6 physical pins, which are used
for MSDC2 on MT6735 but don't exist on MT6735M (since MSDC2 doesn't exist on it
to begin with). In preparation to document DT bindings for this pin controller,
the existing documents for MT67xx SoCs are combined into one in order to
eliminate duplicate property definitions and standardize pin configuration node
names.

Yassine Oudjana (4):
  dt-bindings: pinctrl: Combine MediaTek MT67xx pinctrl binding docs
  arm64: dts: mediatek: mt6797: Make pin configuration nodes follow DT
    bindings
  dt-bindings: pinctrl: mediatek,mt67xx-pinctrl: Document MT6735 pin
    controller bindings
  pinctrl: mediatek: Add MT6735 pinctrl driver

[PATCH 1/4] dt-bindings: pinctrl: Combine MediaTek MT67xx pinctrl binding docs

[Yassine Oudjana]

From: Yassine Oudjana <y.oudjana@protonmail.com>

Documents for MT6779, MT6795 and MT6797 that currently exist share
most properties, and each one has slightly differently worded
descriptions for those properties. Combine all three documents into
one common document for all MT67xx SoC pin controllers, picking a few
parts from each and accounting for differences such as items in reg
and reg-names properties. Also document the MT6765 pin controller
which currently has a driver but no DT binding documentation. It should
be possible to also include bindings for MT8183 and MT8188, but these
have some additional properties that might complicate things a bit,
so they are left alone for now.

Hello Yassine,
nice cleanup over here!

There's a catch though: as far as I know, wildcards are not permitted... so you
should, at this point, merge all of these in mediatek,mt6779-pinctrl.yaml instead.

Before jumping to that, though... Krzysztof, can you please confirm (or deny)?

Regards,
Angelo

Wildcards are not allowed in compatibles. In filename wildcards or
family name could work if they are really going to match the devices. I
have doubts here. 67xx is quite a lot of different devices, so I am not
sure this will cover them all.

I would prefer one name (oldest SoC or lowest number).

Best regards,
Krzysztof

Lowest number (and probably oldest too but not sure since mediatek 
naming conventions are a bit weird) currently documented is mt6779, but 
mt6765 gets documented in this patch and mt6735 (this one I know for 
sure is older than the rest) in a following patch, so do I just stick 
with mt6779 or do I change it in the following patches documenting 
mt6765 and mt6735?

Thanks,
Yassine

I see the sequence as:

1. You merge mediatek,mt6797-pinctrl.yaml into mediatek,mt6779-pinctrl.yaml; then
2. Adding MT6765 documentation to mediatek,mt6779-pinctrl.yaml; then
3. Adding support for MT6735, documentation goes again to 6779-pinctrl.

This means that you're working with mediatek,mt6779-pinctrl.yaml :-)

P.S.: That was also a suggestion about how to split things per-commit!

Angelo

And mediatek,pinctrl-mt6795 gets merged here too I assume?

Yeah sorry about forgetting that one. Anyway, obviously, do one merge operation
per commit!

No, this is not like old bindings at all. It's not merging, it's a
change sneaked inside huge diff. Also - probably totally untested on DTS
(or old bindings were broken).

That's a no-go.

Actually this change was made specifically so that it remains (probably 
becomes?) compatible with existing DTS and passes checks. mt6779.dtsi 
currently has the syscon compatible string but it wasn't listed along 
with mediatek,mt6779-pinctrl in the old document, but instead there was 
something in the description about putting the pinctrl node under a 
syscon node, which isn't the case in the existing DTS. This patch 
passed both dt_binding_check and dtbs_check. Anyway, I see how I failed 
to describe this change, so I'll go through the patch again and try to 
find any other small changes I might've made and forgotten about, and 
either put them in separate patches or describe them in the commit 
message, whichever one you think is better. Also, do I make those 
changes in the original documents then combine or combine first then 
make them in the new one?

Thanks,
Yassine

[PATCH 3/4] dt-bindings: pinctrl: mediatek,mt67xx-pinctrl: Document MT6735 pin controller bindings

[Yassine Oudjana]

From: Yassine Oudjana <y.oudjana@protonmail.com>

Add bindings for the pin controller found on MediaTek MT6735 and
MT6735M SoCs, including describing a method to manually specify
a pin and function in the pinmux property making defining bindings
for each pin/function combination unnecessary. The pin controllers
on those SoCs are generally identical, with the only difference
being the lack of MSDC2 pins (198-203) on MT6735M.
