This patch set adds basic support for the Tesla Full Self-Driving (FSD)
SoC. This SoC contains three clusters of four Cortex-A72 CPUs,
as well as several IPs.
Patches 1 to 8 provide support for the clock controller
(which is designed similarly to Exynos SoCs).
The remaining changes provide pinmux support, initial device tree support,
and SPI, ADC, and MCT IP functionality.

Nitpick: Drop the white-spaces between if-then. It's easier to spot the
if-blocks if they are together.

Drop this whitespace as well.
Rest looks good to me, except the discussion about the compatible.

Drop this whitespace as well.
Rest looks good to me, except the discussion about the compatible.

Clock controller driver of FSD platform is designed to have separate
instances for each particular CMU. So clock IDs in this bindings header
also start from 1 for each CMU block.

Add compatible for Tesla Full Self-Driving SoC. The
pinctrl hardware IP is similar to what found on most of the
exynos series of SoC, so this new compatible is added in
samsung pinctrl binding.

Please rebase this on my latest Samsung pinctrl dtschema patches. You
also need a tesla vendor prefix patch (separate).

The SPI (v3) and pinctrl (v2) dtschema patches are on mailing lists.
They seem to be done, so after merge window they will make to
linux-next. If you want earlier, grab them from mailing list or from
branches:

It's confusing and probably not accurate. In your series fsd is three
things in the same time: an architecture, a SoC and a board (DTS). The
last two should definitely be different. You probably have some eval
board (how it is called also in Tesla open source git) or some specific
product board.
I cannot judge how different this is from Exynos subarchitecture -
looking at patches it is not different - so I could understand a FSD
sub-arch with only one SoC.

Understood, let me clear this confusion in the patchset-2 where fsd board will have its own compatible and

Is it based on another SoC design then? Most new SoCs are derived from
some other
one, so it makes sense to put it into the same family. E.g. the Apple
M1 takes bits from
both Exynos and PA-Semi SoCs but has more newly added components than
either one.
I would argue that if this SoC shares the pinctrl, clock, spi, adc,
and timer implementation
with Exynos, we should consider it part of the Exynos family,
regardless of what other
blocks may exist next to those.

It seems Apple M1 shares only few bits with SoC. I am aware of only UART
driver as directly re-usable.

Plus: UART, watchdog, PWM, I2C, I2S, USB PHY, DWC3 USB (in Exynos
flavor), UFS (also in Exynos-looking flavor), MFC (video codec), some
similarities in DW PCIe, TMU (thermal). Looking at DTS there are
differences but just few comparing to most of shared blocks.
Additionally SoC BSP (and maybe SoC itself...) was actually developed or
co-developed by Samsung, judging by copyrights in the BSP code. Even the
original DTSI has:
TURBO TRAV SoC device tree source
Copyright (c) 2017 Samsung Electronics Co., Ltd.
Tesla could still customize it a lot, but it is a strong hint that most
of it came from Samsung LSI and shares with existing Samsung designs.
Have in mind that recent Exynos chips are significantly different than
early ARMv7 or ARMv8 designs and we still consider them part of Exynos
family.

Yes. I don't see the benefit of keeping it outside of Exynos. It will
sprinkle "depends on ARCH_EXYNOS || ARCH_FSD" all over (or depend on
Exynos like you suggested).

Yes. I don't see the benefit of keeping it outside of Exynos. It will
sprinkle "depends on ARCH_EXYNOS || ARCH_FSD" all over (or depend on
Exynos like you suggested).
Best regards,

I think it's a misnomer to call SoCs like these "based on each other".
What often happens is that a manufacturer reuses IPs between designs
since they're there, they're available and they work and there's
little reason to redo it, etc.
For cases such as a vendor building a custom SoC for a specific
customer (which, from the looks of this patchset seems to be the case
-- this is not something I say with insider information :-), it makes
sense to reuse IP blocks in the same way. It's actually a competitive
benefit of the vendor to have silicon-proven IPs in this manner.
Does this mean that this custom-built product is a part of a product
family? I don't think that's the primary conclusion I would make --
it's more complex than that. And it also doesn't make all that much of
a difference whether it's considered a family member or not. I would
be very surprised if this SoC had a Samsung marketing name, since to
my knowledge it's not sold to any other customer.
If all we're arguing here about is a toplevel compatible and a Kconfig
variable, then I don't see a need to spend a whole lot of time on this
-- as long as it's not a change that ends up proliferating the whole
source tree. I.e. if you want to create a new sub-arch, make sure it
selects or depends on EXYNOS so you don't need to sprinkle a lot of
"EXYNOS" -> "EXYNOS || TESLA" edits in the tree (as per below in the
email).
Same with the DT bindings. Can you just augment to make the tesla
vendor prefix an allowed one for the exynos bindings where it makes
sense? Toplevel board (and SoC) compats can of course still be
independent.

Depend or select (but select is a slippery slope so might be better
avoided) seems like a pretty good option here to me.

How similar it is? I think it is better to duplicate Exynos
selections/options here, instead of selecting entire ARCH. If this would
require "depends on ARCH_EXYNOS || ARCH_TESLA_FSD" everywhere in the
drivers, it's a hint that it is not a separate SoC but it is an Exynos,
so it might not need a new sub-architecture.

No, this is not a fsd.dts, but some board. You call FSD a SoC, so this
should have different name.

These are not bootargs matching SoC. earlycon is purely a debug option.
console is duplicating stdout-path. root and init are also not a part of
DTSI or DTS.

The labels/overrides are with weird order... looks like a mess. Anyway,
clocks should be always enabled, why board has to enable them?

This property looks unsupported. Did you run dtschema checks?

How similar it is? I think it is better to duplicate Exynos
selections/options here, instead of selecting entire ARCH. If this would
require "depends on ARCH_EXYNOS || ARCH_TESLA_FSD" everywhere in the
drivers, it's a hint that it is not a separate SoC but it is an Exynos,
so it might not need a new sub-architecture.

No, this is not a fsd.dts, but some board. You call FSD a SoC, so this
should have different name.

Wrong model, this is DTS, not DTSI.

These are not bootargs matching SoC. earlycon is purely a debug option.
console is duplicating stdout-path. root and init are also not a part of
DTSI or DTS.

The labels/overrides are with weird order... looks like a mess. Anyway,
clocks should be always enabled, why board has to enable them?

This explains why DTS has to enable basic SoC features... why do you
disable your clock controllers?

This property looks unsupported. Did you run dtschema checks?

Agreed, the SoC family options mainly exist so we can quickly enable or
disable drivers based on what a kernel is built for. If most of the drivers
for this SoC are shared with Exynos, I think having a single option is
sufficient, but it may be worth pointing out both in the help text.
If we want to have a separate option (mainly to help users find it), maybe
a 'depends on ARCH_EXYNOS' would be better. How many uses of
ARCH_TESLA_FSD are there?

It is true that FSD shares few IPs with Exynos and it dose contains Telsa specific IPs/ PCIe/some of the PHYs/ GPUs (different then Exynos) etc. to name a few.
And drivers for those will be posted in upcoming phases by Samsung, Telsa etc.
AFA architecture is concerns both Exynos and FSD has completely different architecture (at least at HW level).
In my opinion, it is make sense to have a separate option for FSD.
And as Arnd suggested "'depends on ARCH_EXYNOS" may be the way forward.

It is true that FSD shares few IPs with Exynos and it dose contains Telsa specific IPs/ PCIe/some of the PHYs/ GPUs (different then Exynos) etc. to name a few.
And drivers for those will be posted in upcoming phases by Samsung, Telsa etc.
AFA architecture is concerns both Exynos and FSD has completely different architecture (at least at HW level).
In my opinion, it is make sense to have a separate option for FSD.
And as Arnd suggested "'depends on ARCH_EXYNOS" may be the way forward.

Please make sure you run this thru 'make dtbs_check'. Fix schema
warnings as much as possible and all dtc warnings. If shared with
Samsung, there's probably a bit still missing. I see several warnings
so I won't bother manually reporting them here.

OK, but have in mind that -gpio-bank suffix is not needed now. This
depends on support in the pinctrl driver, which will be applied after
the merge window to different tree or branches than DTS is going to.
Therefore if I apply your DTS with "-gpio-bank" to my next/dt64, the
kernel won't find GPIo banks and won't properly boot. The linux-next
will be fine, just my next/dt64 won't be.
If you're fine with it - use "-gpio-bank" suffix. If you prefer my
next/dt64 to have a fully working Tesla SoC DTS, then stick to old node
naming and let's replace it later.
Best regards,
Krzysztof

Thanks, got it, for now let me send v2 on linux-next (as of today).
As required I will rebase to your next/dt64 and send again.
Which also means that my v2 will not be based on your new pinmux schema.
Probably we will move to that after the merge window.

Looks good, except the discussion about too generic compatible.

Note to self: now that I see that the Samsung "S3C" SPI controller,
which I was thinking of as "some kind of early 2000s legacy" is used
by the very latest silicon I bumped up fixing it to use GPIO descriptors
a bit on my TODO list.

Please use SoC-specific compatible. IP block versions are tricky because:
1. Documentation/datasheet mentioning which SoC has which block version
are not public.
2. Neither are public the datasheets for ADC blocks.
3. The versioning of IP blocks can be inaccurate.
Best regards,
Krzysztof

Exynos's ADC-V3 has some difference in registers set, number of
programmable channels (16 channel) etc. This patch adds support for ADC-V3
controller version.

Hi Alim,
A few minor suggestions below. I'm not seeing a binding update though...
I'd also suggest that it would be more appropriate to break this out as
a separate mini series from the main support so that it can be reviewed
and merge separately. It's not ideal when a list just gets patch 21 of
23 with no cover letter etc sent to it.

Given we have a mixture of required an unrequired elements in this structure
it might be a good idea to add some documentation. Kernel-doc for the whole
structure preferred. Note this isn't necessarily something that needs to be
in this patch given the lack of docs predates this and with the change to make
adc_isr() required that I suggest below things aren't made worse by this patch.

Shouldn't need the cast as cast from void * to another pointer
is always valid in C without the explicit cast.

Don't need this currently as v3_isr() is always matched
with clear_isr() being provided. Having the check implies
otherwise which is probably not a good thing to do until some future
device support (maybe) needs it.

I'd rather see the slightly larger change of providing adc_isr for existing
parts and the conditional part here going away.

Given we have a mixture of required an unrequired elements in this structure
it might be a good idea to add some documentation. Kernel-doc for the whole
structure preferred. Note this isn't necessarily something that needs to be
in this patch given the lack of docs predates this and with the change to make
adc_isr() required that I suggest below things aren't made worse by this patch.

Shouldn't need the cast as cast from void * to another pointer
is always valid in C without the explicit cast.

Don't need this currently as v3_isr() is always matched
with clear_isr() being provided. Having the check implies
otherwise which is probably not a good thing to do until some future
device support (maybe) needs it.

I'd rather see the slightly larger change of providing adc_isr for existing
parts and the conditional part here going away.

I think this should be variable, based on SoC compatible. The mistake
was done already when adding Exynos5420 support by Linaro/Samsung, but
at least let's correct it now.
Older MCTs/SoCs do not support 12 local interrupts, so they do not need
and should not register so many interrupts.
Best regards,
Krzysztof

Does FSD have some version number? The FDS, especially in compatibles,
looks quite generic, so what will happen if a newer SoC comes later? You
would have:
- tesla,fsd-pinctrl
- tesla,fsd-xxxx-pinctrl (where xxxx could be some new version)
This will be extra confusing, because fsd-pinctrl looks like the generic
one, while it is specific...
Best regards,
Krzysztof

The public sources from Tesla on github uses "turbo,trav" here, but
that's also not a versioned name. The platform itself (hw3/hw31 -- 3.1
I presume?) has numbering, but that's system and not SoC:
https://github.com/teslamotors/linux/tree/tesla-4.14-hw3/arch/arm64/boot/dts/turbo
It would be easy to do "fsd2" for naming/numbering if needed for
future versions, for example. I'm not so worried about this,
especially if there's no corresponding internal version numbering that
this would map naturally to.

AFAIK, there is no version for FSD SoC (like we see on Exynos or any other SoC)
In case something comes in future, may be just adopt as Olof suggested in the other thread like fsd2 etc..

The naming is still confusing. The SoC is FSD, compatible is "fsd" but
entire sub-architecture is also FSD called. Therefore it looks like
creating entire sub-architecture for only one SoC, which actually in
multiple pieces is or looks like Samsung Exynos (designed by Samsung,
using several blocks from Exynos SoC).

Krzysztof

I'm not thrilled by their naming. Intel does not produce "Intel
Fastest in world SoC", and this chip is not actually suitable for
autonomous driving :-(.

And AMD's Infinity Fabric isn't.... infinite. Things have names.
That discussion seems off-topic for this patchset. It references a
marketing name used by the company, and as such it makes sense to be
able to cross-reference:
https://www.tesla.com/support/full-self-driving-computer
Tesla seems to have moved away from the initial "Hardware 3" naming
scheme, so using this naming seems as good as any.

I'd prefer to call it Tesla HW3. Even wikipedia has that name, no need
to do false advertising for Tesla, and we'll have good names for
HW2.5 and HW4 if it comes out. We normally use codenames, not
marketing names.
