[PATCH 1/7] dt-bindings: pinctrl: Add support for Broadcom STB pin controller

[PATCH 1/7] dt-bindings: pinctrl: Add support for Broadcom STB pin controller

[Ivan T. Ivanov]

It looks like they are few revisions of this chip which varies
by number of pins. Perhaps not all of them are available on the
market. Perhaps some of them where early engineering samples,
I don't know. I decided to keep all of them just in case.

bcm2712 is Rpi, so not really STB. The name is confusing. Please use
compatible as filename, so:
brcm,bcm2712-pinctrl.yaml

I suggest going with patternProperties, fixed suffix for node names and
$defs. See for example:
Documentation/devicetree/bindings/pinctrl/qcom,x1e80100-tlmm.yaml

Missing example. I don't see this being part of other complete device,
so example is a requirement.

OK, title can be like this, no problem, although then please expand what
"STB" means.

Bindings still are supposed to use compatible as filename.

The BCM2711 had also some revisions and we avoided successfully multiple
versions of the RPi 4B DTS. So it would be nice if someone can explain
if C0 & D0 are available in the market? Otherwise we may end up with
multiple versions of the RPi 5 DTS.

I'm missing an explanation in the commit message, what's the difference
between brcm,bcm2712-pinctrl and brcm,bcm2712-aon-pinctrl?

According to the driver brcm,bcm2712-pinctrl is the same as
brcm,bcm2712c0-pinctrl. So the former is more a fallback?

Ok.

IIUC, you suggest to rename compatible string from brcm,bcm2712-pinctrl
to brcm,brcmstb-pinctrl?!

AFAIK A0 and B0 silicon were never commercialised.
C0 is the current revision in use with Pi5.
D0 will be in devices imminently. CM5 will use it from launch, but
subsequently standard Pi5s will do as well.

In addition to putting in the few fixes that were desired, some
registers and DMA dreqs got shuffled around, hence some drivers will
need additional compatible strings (vc4 certainly does) and other
minor DT tweaks.

Checking our downstream dt files, we have bcm2712d0-rpi-5-b.dts[1]
that includes and patches the original (C0) bcm2712-rpi-5-b.dts[2].
The cleaner option would be to have a common bcm2712-rpi-5-b.dts(i)
and separate bcm2712c0-rpi-5-b.dts bcm2712d0-rpi-5-b.dts which include
the base and add the relevant customisations. Later a
bcm2712d0-rpi-cm5.dts DT should be able to include that same base file
as well.

I'm not quite sure why the GPIO names are redefined in our d0 file -
other than the unused ones using "-" instead of "", they appear
identical.

> between brcm,bcm2712-pinctrl and brcm,bcm2712-aon-pinctrl?

Two separate instantiations of the same IP block, but they differ in
the number of pins that are associated and the pinmux functions for
each of those pins. AFAIK there is no way from DT to specify those
pinmux function names, so otherwise
/sys/kernel/debug/pinctrl/<node>/pins will give the wrong function
mappings.

I'd need to check with Phil (who's on holiday this week) or Dom, but I
believe you are correct that "brcm,bcm2712-pinctrl" is a fallback.
Most likely due to our early DT files not having the c0 designation.
Obviously for mainline that is irrelevant, so dropping the
non-specific compatibles is fine.

I hope that makes some more sense.

Yes, my request is that this or a similar explanation should go to the
commit message, because not all reviewers know the IP block. It would be
great to explain the aon part. Always on?

I agree.

[PATCH 0/7] Add pin control driver for BCM2712 SoC

[Andrea della Porta]

Hi,

The following patches add a pin control driver for the BCM2712 SoC and few
pin/gpio Devicetree nodes for Raspberry Pi 5.

Device driver is follow up version on what Andrea posted in April [1].

It is based on sources from here [2]. I just made few cosmetic changes
and addressed review comments from earlier submission. I don't have
documentation for this controller.

Patch 4 wire up power button on RPi5.

Patch 5 adds WiFi Devicetree node for RPi5.

Patch 6 adds Bluetooth Devicetree node for RPi5.

All this have been tested as kernel was directly booted RPi5 via
kernel= config.txt option and cmdline.txt file with following content
(Note I am using Tumbleweed RPi raw images)

# cat /boot/efi/cmdline.txt
root=/dev/mmcblk0p3 rootwait rw systemd.show_status=1 console=tty ignore_loglevel earlycon console=ttyAMA10,115200

With all these patches Bluetooth and Wifi are working fine (tm) with
firmware files provided by openSUSE Tumbleweed.

All comments and suggestions are welcome!

Happy hacking!
Ivan and Andrea

CHANGES in V2: (all patchset is based upon linux-next/master)

--- PINCTRL DRIVER ---

- dropped bcm2712_c0_aon_sgpio_pin_funcs[] and bcm2712_d0_aon_sgpio_pin_funcs[]
  struct array definitions since they are not used anywhere.

- dropped 'arg' variable in brcmstb_pinconf_set() as it's not used.

- updated copyright info at the top.

- several changes in the declared macros. Renaming the macro name and the
  macro parameters to better reflect the semantic.

- reworked MUX_BIT() macro to be more streamlined and easy to
  understand.

- added PAD_BIT() macro to avoid code duplication.

- renamed 'lock' variable to 'fsel_lock'.

- added some comments about non-existent pins on D0 silicon revision pin
  declarations.

- brcmstb_pinctrl_fsel_set(), brcmstb_pull_config_set()  and
  brcmstb_pinconf_set() (and functions that call them) can now return -EINVAL
  as error.

- added myself as MODULE_AUTHOR.

- dropped the 'brcm,bcm2712-[aon-]pinctrl' fallback compatible. Only c0 or d0
  compatibles are permitted now.


--- DTS ---

- moved 'clock-frequency' property from (uarta) board dts node to SoC dtsi node.

- added 'brcm,sdhci-brcmstb' compatible and 'clock-names' property to mmc node
  to avoid dt_binding_check errors.

- added 'brcm,bcm7445-gpio' compatible to gpio node to avoid dt_binding_check
  errors.

- renamed all pinctrl pin nodes as per yaml schema (*-state and *-pins).

- changed 'brcm,bcm2712-*pinctrl' to 'brcm,bcm2712c0-*pinctrl' since the
  former was more of a fallback and does not reflect a real silicon revision.

- moved status="okay" to the last entry in 'uarta' node.

- removed 'local-*-address' property from everywhere.

- dropped 'skip-init' property in 'uarta' node since it does not apply to
  linux kernel.

- renamed 'pwr-button' node to 'gpio-keys' and 'pwr_key' node to
  'power_button'.

- dropped an userspace related 'brcm,gpio-direct' property from gpio node.



--- DT BINDINGS ---

- binding schema file renamed to 'brcm,bcm2712c0-pinctrl.yaml' to reflect the
  compatible name.

- dropped the 'brcm,bcm2712-[aon-]pinctrl' fallback compatible. Only c0 or d0
  compatibles are permitted now.

- added example section.

- moved allOf: block at the beginning of the schema.

- dropped some unnecessary new lines.

- replaced current layout to describe the pin subnodes with patternProperties
  (nodes now end with -state and -pins).

- expanded the schema description to give some context about STB family of pin
  controller and added some details about C0 and D0 silicon variants. This is
  also reflected in the commit message.


--- MISC ---

- enabled CONFIG_PINCTRL_BRCMSTB in arm64 defconfig.

[PATCH 1/7] dt-bindings: pinctrl: Add support for Broadcom STB pin controller

[Andrea della Porta]

From: "Ivan T. Ivanov" <iivanov@suse.de>

The STB pin controller represents a family whose silicon instances
are found e.g. on BCM2712 SoC.

In particular, on RaspberryPi 5, there are two separate instantiations
of the same IP block which differ in the number of pins that are
associated and the pinmux functions for each of those pins. The
-aon- variant stands for 'Always On'.

Depending on the revision of the BCM2712 (CO or D0), the pin
controller instance has slight differences in the register layout.

[PATCH 7/7] arm64: defconfig: Enable BCM2712 on-chip pin controller driver

[Andrea della Porta]

Select the on-chip pin controller driver for BCM2712 SoC.

On RapsberryPi 5 devices it is primarily needed to operate the
bluetooth and WiFi devices, to configure the uSD interface
and the power button.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250715 (exact match)

If this is not the correct base, please add 'base-commit' tag

Sorry, I've just realized this patchset has been sent with no V2 in the subject.
Anyway, I'm preparing a new revision (which will be V3) after amending it after
Rob's automated script warning.

I'll also split the patchset into two, oen with binding / driver for SoC pin
controller and another with thie remaining DTS related patches.

Many thanks,
Andrea
