Hi folks,

This series adds initial SoC support for the GS101 SoC and also initial board
support for Pixel 6 phone (Oriole).

The gs101 / Tensor SoC is also used in Pixel6a (bluejay) and Pixel 6 Pro (raven).
Currently DT is just added for the gs101 SoC and Oriole.

The support added in this series consists of:
* cpus
* pinctrl
* some CCF clock implementation
* watchdog
* uart
* gpio

This is enough to boot through to a busybox initramfs and shell using an upstream
kernel though :) More platform support will be added over the following weeks
and months. Currently we boot with clk_ignore_unused parameter but this will be
updated as more clocks and platform support lands.

For further information on how to build and flash the upstream kernel on your
Pixel 6, with a prebuilt busybox initramfs please refer to the script and
README.md here:

https://git.codelinaro.org/linaro/googlelt/pixelscripts

I've also included the dtbo overlay containing board_id and board_rev in this
series as otherwise the LK bootloader will bootloop if this is not present in
the dtbo partition. It seems like it would be nicer for the upstream kernel to
build all the DT required to boot upstream kernel on a production phone rather
than having to obtain this dtbo from some other place, but if it is a pain point
then I can remove it.

Many thanks,

Peter.

No, these are not bindings.

We do not keep interrupt numbers as bindings. Please drop entire file.

You need to add to allOf: a new "if:then:else:" which will:
1. narrow this for Google (with some description - is it interrupt per
GPIO? per bank?)
2. else: maxItems: 1

For "google,gs201-wdt the comment should be "for Google gs201".

Is this patch out of order? ARCH_GOOGLE_TENSOR hasn't been defined at this

Since we are creating unified kernel images, having other drivers is not
a problem.

SOC_GOOGLE will work exactly the same and depend on ARCH_EXYNOS or
appear everywhere as ARCH_EXYNOS. We already had this talk with Tesla.

And hardware is Exynos. Tesla FSD and Google Tensor is Exynos, even if
you do no like calling it.

There is no arbitrary dependency. We call it all Exynos hardware,
because this is Exynos.

I remember what you were pushing for removal of ARCH_EXYNOS and there
waas clear feedback, not only from me: this is against communities goals.

I'm glad you brought up Exynos UART because this is where one of the
limitations is introduced. For example, if you want to modularize out all the
vendor specific drivers from the core kernel to create a common arm64 kernel
binary that works on all ARM64 devices, you will not be able to build in the
early console UART drivers without enabling the respective ARCH_* configs.
Being able to include SERIAL_SAMSUNG and SERIAL_MSM without all the vendor
specific drivers that ARCH_EXYNOS and ARCH_QCOM select is very valuable for
debugging early boot issues.

I understand that ARCH_* configs are used to selectively pick which device tree
blobs are built, but forcing developers to pick all or nothing is where I have
a problem.

Will

When you build single kernel there is never need to NOT ENABLE
respective ARCH configs. Please describe me upstream case for such need
to NOT ENABLE.

Really? How related? The drivers are independent. You describe some
out-of-tree development process which we never needed for upstream work.
And we did here quite a lot of upstream, specially if you look at ARCH_QCOM.

No one forces you to pick up everything or nothing. You select
ARCH_EXYNOS and still can drop all optional drivers. It's true you
cannot drop mandatory drivers, but you are upstreaming Exynos platform,
right? We do not talk about your out-of-tree Google work because it does
not matter.

Bank types are defined at the top. "type_6" is way too vague. Look how
the others are named.

Please split the patch into two: one of adding new filter code and
second for new Google SoC.

Arguments: first drv_data, then bank, then width, then sel... and what
is sel actually?

Also, why do you need width if it is always 0? Will it be different in
next pinctrl controllers? So the filter is per entire bank?

This is always 0, what's the point?

Please document the layout of the registers in exynos_eint_flt_config()
comment (not kerneldoc). Also document what do you want to achieve here
- set entire bank to one filter for the suspend/resume?

I don't think you use in this header anything from bitfield.

Right: in general, all drivers are independent of the platform
besides the typical 'depends on ARCH_FOO || COMPILE_TEST' dependency,
but I think it's worth mentioning the known exceptions, so Greg and
Will can take that fight to the respective places rather than
discussing it in the platform submission:

- Some subsystems are considered 'special' and the maintainers
  prefer the drivers to be automatically selected based on the
  ARCH_* settings instead of having user-visible options. This is
  traditionally true for large chunks of drivers/irqchip,
  drivers/clocksource and drivers/pinctrl, though it has gotten
  better over time on all of them.

- Some older 32-bit platforms are still not as modular as we'd
  like them to be, especially the StrongARM (ARMv4) platforms that
  require a custom kernel build, and some of ARMv4T and ARMv5
  boards that are still missing DT support. These tend to require
  drivers they directly link to from board code, so disabling
  the drivers would cause a link failure until this gets
  cleaned up.

- A couple of drivers are force-enabled based on the ARCH_*
  options because booting without these drivers would risk
  permanent damage to hardware, e.g. in overtemp or overcurrent
  scenarios.

- ACPI based platforms require the PCI host bridge driver to
  be built-in rather than a loadable module because ACPI
  needs to probe PCI devices during early boot.

- Some subsystems (notably drivers/gpu/, but others as well)
  have an excessive number of 'select' statements, so you
  end up surprise-enabling a number of additional drivers
  and subsystems by enabling certain less important platform
  specific drivers.

So if the argument is that the existing upstream Exynos platforms are required
to have these drivers built-in to the kernel to boot:
    COMMON_CLK_SAMSUNG
    CLKSRC_EXYNOS_MCT
    EXYNOS_PM_DOMAINS if PM_GENERIC_DOMAINS
    EXYNOS_PMU
    PINCTRL
    PINCTRL_EXYNOS
    PM_GENERIC_DOMAINS if PM
    SOC_SAMSUNG

...then that is understandable and we can work to fix that.

My last question then is -- why do we need a new ARCH_GOOGLE_TENSOR config in
the platform Kconfig? For example, I don't really like this:

diff --git a/drivers/clk/samsung/Kconfig b/drivers/clk/samsung/Kconfig
index 76a494e95027..4c8f173c4dec 100644
--- a/drivers/clk/samsung/Kconfig
+++ b/drivers/clk/samsung/Kconfig
@@ -13,6 +13,7 @@ config COMMON_CLK_SAMSUNG
        select EXYNOS_5420_COMMON_CLK if ARM && SOC_EXYNOS5420
        select EXYNOS_ARM64_COMMON_CLK if ARM64 && ARCH_EXYNOS
        select TESLA_FSD_COMMON_CLK if ARM64 && ARCH_TESLA_FSD
+       select GOOGLE_GS101_COMMON_CLK if ARM64 && ARCH_GOOGLE_TENSOR

What happens when we have GOOGLE_GS101_COMMON_CLK, GOOGLE_GS201_COMMON_CLK, and
so on? How are we going to pick the right driver when we have a generic
ARCH_GOOGLE_TENSOR config? Ideally, we should have one Exynos clock driver that
can detect what hardware is running (using the DT) to determine what it needs
to do. If you really want to compile out the other vendor's clock drivers using
some configs, then we should do that with SOC_GS101, SOC_GS201, SOC_TESLA_FSD
configs (not ideal though). With that approach, we could drop the platform
ARCH_GOOGLE_TENSOR config and create an SOC_GS101 config that can be used for
things like the COMMON_CLK_SAMSUNG driver (for now) and building the GS101 dtb.

Let me know your thoughts.

Thanks,
Will

Agree, but it should be fine to have as a SoC-specific .dtsi under
arch/.../google/gs101-irq.dtsi though!

Nothing happens... or happens anything you wish. Did you read the
motivation why this was created like this?

You do not have to pick. You select ARCH_GOOGLE_TENSOR and proper pick
is done by you. Nothing to do more.

It's already like this. We're done.

Whether you call it SOC or ARCH it is the same. We organized it as ARCH.

There is no need for this. ARCH does exactly the same.

Will fix.

Sel parameter is just setting the FLT_SEL bitfield
0 = Delay filter
1 = Digital filter

The downstream driver never set the width bitfield so I we could remove
this width logic and add it back if it's ever required.

> So the filter is per entire bank?

The filter is selectable per pin. So each pin has a FLT_EN, FLT_SEL and
FLT_WIDTH bitfield.

Yeah we could remove this, and add it back if it's ever required. Let

Yes exactly it is looping through setting all the pins in the bank to
one filter on
suspend and resume. I will add a comment as you suggest.

Hi Peter,

Heads up, in case you are not aware Arm SoC timeframes: we are at rc5,
so it means that anything targeting v6.7 should be applied this working
week, before rc6. At least as ARM SoC is concerned.

Best regards,

Thanks, and thankyou for reviewing the series so promptly.

That's all fine, it makes sense and it was what I was expecting. Maybe
we can try and get you some Pixel 6 hardware as well. The only other
Exynos hardware I have for testing unfortunately is the e850 board Sam
has been working on.

Coincidentally https://www.crowdsupply.com/0xda/usb-cereal just started
shipping. Which is quite nice (albeit coincidental) timing, as anyone who
has a Pixel 6 device can order one so they can run upstream kernels on
their phone and have the debug UART available (which currently is the
only way to really interact with the system until we bring up more IO).

regards,

Okay, sounds good. Thanks for the responses.
