Hello,
Here I want to introduce a new patch series, which aims to support IOMUX
functions provided by SIUL2 [System Integration Unit Lite2] on S32 SoCs,
such as S32G2. This series is originally from NXP's implementation on
CodeAurora[1] and it will be required by upstream kernel for supporting
a variety of devices on S32 SoCs which need to config PINMUXs, such as
PHYs and MAC controllers.
Thanks,
Chester
Changes in v3:
- dt-bindings:
- Remove the minItems from reg because there's no optional item for
s32g2.
- List supported properties of pinmux-node and pincfg-node and add more
descriptions.
- Adjust the location of "required:".
- Fix descriptions and wordings.
- Rename the yaml file to nxp,s32g2-siul2-pinctrl.yaml.
- Rename pinctrl-s32g.c to pinctrl-s32g2.c
- Adjust Kconfig options [menu-invisible] and names [S32G -> S32G2].
- Add .suppress_bind_attrs
- Drop the .remove callback and replace the module_platform_driver() call
with builtin_platform_driver()
Changes in v2:
- Move the "nxp,pins" ID range information from DT to the driver.
- dt-bindings:
- Fix schema issues.
- Add descriptions for reg entries.
- Revise the example.
- Refine the compatible name from "nxp,s32g-..." to "nxp,s32g2-...".
- Fix the copyright format suggested by NXP.

You cannot have underscores as node names, so what do you mean here? You
need to fix your DTS not introduce bad practices to mainline kernel.

The same comment also applies here.

This should also change to something like:
llce_can0_pins {
llce_can0_grp0 {
...
}
}
Otherwise, this and PATCH 2/2 look good to me.

You have known values, then use them. This is much more readable in DTS.

The main reason of mapping with register values [0-7] is to simplify the
driver implementation while handling register r/w. To improve readability
as you suggested, I am thinking of having a DT header "s32g2-pinfunc.h" with
a few binding macros/helper as below, the only difference compared to v3 is
using S32G2_PINMUX and S32G2_SLEW_XXXMHZ macros rather than pure integers
to represent pinmux and slew-rate property values.

Chester

Define bindings for the DTS, not for the drivers.

Binding headers is not a place for register values. By definition -
these are bindings, not hardware description. Hardware description is
DTS. Feel free to store them in DTS headers, but anyway this does not
solve the issue here.
The issue is: you store register values in DTS, which is limited, not
extendable description. Each of your devices would need entirely
different binding for this because register values can change between
every SoC version. Several other pinctrl bindings use similar approach,
but they have not got a clear mapping to values (e.g. they have fast and
slow). For the case with real values, use the same solution as
drive-strength - real values.

NAK for bindings.

Hi Chester,
thanks for your patch!

Should this driver really be grouped together with the legacy branded
"freescale" stuff? Does it share any hardware or structure or code
with the Freescale drivers?
Maybe you should bite the bullet and created drivers/pinctrl/nxp?
Also create a new MAINTAINERS entry so we do not get the
Freescale legacy maintainer list.
Overall the driver looks good, I am a bit sceptic about the things
that Kryzstof is talking about as well so that needs to be resolved.
Yours,
Linus Walleij
