Hi folks,

Thanks to everyone who reviewed the previous rounds. V5 incorporates
the review feedback received so far, and is rebased onto linux-next as
per Krzysztof request to incorporate all his dt-binding changes for
exynos.

As this series spans multiple subsytems the expectation is that Krzysztof
will apply the whole series through the Samsung SoC tree. If the relevant
subsystem maintainers can give a acked-by or reviewed-by on the relevant
patches that would be most appreciated!

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) phones. Currently DT is added for the gs101 SoC and Oriole.
As you can see from the patches the SoC is based on a Samsung Exynos SoC,
and therefore lots of the low level Exynos drivers can be re-used.

The support added in this series consists of:
* cpus
* pinctrl
* CCF implementation of cmu_top, cmu_misc & cmu_apm
* watchdog
* USI 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.

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

Note: Booting without a dtbo works with some versions of the bootloader
but crashes on others. Later versions aren't necessarily better. You can
get the bootloader version with `fastboot getvar version-bootloader`
Known good bootloader versions are: -
- slider-1.3-11000330
- slider-1.2-9152140
Known to crash without dtbo
- slider-1.3-10780582

kind regards,

Peter.

Except for my nitpicks below (very minor, can be ignored):

Not really needed for the particular example below, but I guess it's
ok to have it here for the reference.

Having 0x0 here doesn't match how it's done in gs101.dtsi in this
series. If you remove it, then above soc node and its properties can
be removed too.

As I understand, all those parts like IPCLKPORT, BLK, UID (RSTNSYNC
probably too) -- they don't really mean anything in the context of the
driver, just noise. And if you remove those -- there won't be any
conflicts with other names, because those bits are not the unique
parts. Following the TRM letter for letter in this case just makes
things extremely long without adding any value IMHO. For example, that
name above might be:

    CLK_CON_GAT_GOUT_APM_SS_DBGCORE_SS_DBGCORE_HCLK

or even

    CLK_CON_GAT_GOUT_APM_SS_DBGCORE_HCLK

would be fine.

In clk-exynos850 driver I removed all those parts, because they make
it pretty much impossible to read both the driver and dts. And yeah,
because those names consequenty lead to very long string names, dts
will be hard to read too, which is even worse. But again, that's only
my IMHO.

Just want to give you one more example for my rant above. Look how
much easier it is to understand this name (than above one):

    CLK_CON_GAT_MISC_OSCCLK_CLK

Which also turns this (public API!):

    "gout_misc_rstnsync_clk_misc_oscclk_ipclkport_clk"

into this:

    "gout_misc_oscclk_clk"

So if you want to be consistent, it should be
"gout_misc_misc_misc_....". My point is -- Samsung's naming in TRM is
insane. They wanted to stick to some very detailed and unified naming
schema (or just generated those names from some internal clock tree
data), granted. But I'm just not sure if it's the best idea to follow
it in driver's code.

I verified boot and that the pinctrl driver is probing. When I tested

  echo mem > /sys/power/state

I wasn't able to re-wake the device (not sure how to send an eint gpio on
a phone form factor). I tried with no_console_suspend but that hits a SError
Interrupt (likely due to a PMU secure register access). Let me know if there's
anything else I should test out.

Thanks,
Will

This whole function needs a refactoring. Do you think below code looks better?

The code below looks quite self-explanatory to. Maybe remove all
comments like this? If you don't think exynos_eint_flt_config() is
clear, maybe rename it to exynos_eint_set_filter().

It fits the previous line just fine, no need to break the line.

Also, if you use the refactored version of exynos_eint_flt_config() I
mentioned above, you can drop all 'if' conditions like this.

Suggest using BIT() macro. Btw, checkpatch with --strict option
suggests it too :)

the function declaration.

Isn't it "samsung,uart-fifosize"? Or it was intended this way?

Other than this, LGTM (my R-b tag is already present in this patch).

Nitpick: this empty line is not needed.

Still feels fishy to me that it was decided to have this file instead
of re-using existing Exynos constants. For example, in Exynos850 I
used common constants and it was ok, but it's not ok for this SoC,
althought they look *identical* in a sense of pinctrl. And all those
constants already exist, also identical. So I wonder why something
like this shouldn't be done for Exynos850 as well. But ok.

Please check commit f4324583cd4d ("arm64: dts: exynos: move aliases to
board in Exynos850"). At least for Exynos850 the serial alias was
moved to the board dts by Krzysztof.

Don't you already have real USI/UART clocks implemented in your clock driver?

Krzysztof, can you please advice which scheme is preferred right now:
sorting by name or by address? I saw your patch for dts style doc, but
just want to know the current state of affairs.

I can't see this compatible in USI driver. Does it make sense to add it there?

The same concern as above. I think I saw those clocks already
implemented in gs101 clock driver.

Doesn't CMU_APM take any clocks from CMU_TOP?

Just a suggestion: it might be relatively simple to add syscon-reboot
node in pmu_system_controller, and it might just work. One more
feature for free! :)

Thanks! If a v6 is required I will fixup these nitpicks as well.

Good spot! Seems I forgot to update the example when switching to
address-cells = <1>

Use coding style, so sorting by unit address in DTSI and by
label/phandle of overrides in DTS.

Coding style was not yet applied, but I don't see any objections to it
so it is just a matter of days.

The advantage of keeping the same name as in the data sheet is that then it's easy to
correlate between driver and hardware and future / other hardware.
By arbitrarily diverging from the TRM you make life much harder for yourself when you
have to look at this again in 12 months time after you've forgotten your name mangling
approach; you also make it harder for everybody to review the driver or to use the
driver as a reference in the future for other hardware, as nobody except you knows
what kind of name-mangling was applied and which register (or clock in this case) is
really meant.


Cheers,

EXYNOS9_FLTCON_DELAY and EXYNOS9_FLTCON_DIGITAL now so yes enum is no
longer required.

Hi Sam,

Thanks for your review. I've trimmed the non relevant parts of the
email a bit at Krzysztofs request.

Good spot! These two dividers with reserved lower bits should be fixed
factor clocks. I've fixed in v6.

I would like to keep the register names unmodified, as I mentioned
previously mangling them makes checking with the datasheet much
harder. As the name in the header and string are already mangled a bit
I'm OK with mangling that a bit more.

With that in mind I've done the following mangling in v6: -

Register name: CLK_CON_GAT_GOUT_BLK_APM_UID_APBIF_GPIO_ALIVE_IPCLKPORT_PCLK

Replace `CLK_CON_GAT_GOUT_BLK_<blockname>_UID_` with `CLK_GOUT_<blockname>_`
Replace ` _IPCLKPORT` with nothing
Replace `_RSTNSYNC` with nothing

So you end up with:

GATE(CLK_GOUT_APM_APBIF_GPIO_ALIVE_PCLK,
            "gout_apm_apbif_gpio_alive_pclk", "gout_apm_func",
             CLK_CON_GAT_GOUT_BLK_APM_UID_APBIF_GPIO_ALIVE_IPCLKPORT_PCLK,
             21, 0, 0),

That still enables cross referencing with the datasheet via the
unmodified register name, but the dt binding define and string are
slightly shorter like you wanted. The mangling described above the
vast majority of clock names look fine. There are a couple of
anomalies though like  `CLK_GOUT_MISC_MISC_CMU_MISC_PCLK` and
`CLK_GOUT_APM_APM_CMU_APM_PCLK`. I think it is a *really* bad idea to
do custom mangling on these specific names though.

Will fix. The order here should match the register offsets

CLK_CON_GAT_GOUT_BLK_APM_UID_APM_USI0_UART_IPCLKPORT_IPCLK,
CLK_CON_GAT_GOUT_BLK_APM_UID_APM_USI0_UART_IPCLKPORT_PCLK,

I've revisited the 6 clock gates described above to ensure they are in
register offset order.

In v6 this becomes

GATE(CLK_GOUT_MISC_CLK_MISC_OSCCLK_CLK,
     "gout_misc_clk_misc_oscclk_clk", "dout_misc_busp",
     CLK_CON_GAT_CLK_BLK_MISC_UID_RSTNSYNC_CLK_MISC_OSCCLK_IPCLKPORT_CLK,
     21, 0, 0),

With the naming described above it becomes
"gout_misc_misc_cmu_misc_pclk". Not ideal, and this is one of the
clocks I mentioned above. The overwhelming majority of the clock names
don't have such repetition in their name though. If we start doing
custom mangling on specific clocks it is going to become a nightmare
to track. As I mentioned previously there are thousands of clocks in
the SoC. Most upstream platforms only seem to implement a small subset
of clocks in each CMU which maybe makes it easier to track. Our goal
though is to have full functionality upstream.

No, not yet, hence the dummy clock.

It is not required at the moment, as it is compatible with
samsung,exynos850-usi. I don't want to keep adding more patches to
this series, and then having an endless cycle of nits.

No, these clocks have not been implemented yet, hence the dummy clock.
There is no support for cmu_peric0 bank yet in the clock driver.

Thanks for the suggestion. I tried that previously and it is not
included here deliberately because it relies on more than that to be
functional. Although the register offsets are the same, the PMU
registers are protected from the kernel and are only write accessible
via SMC call on this platform. I have patches ready to send out as a
RFC for that once this initial series is merged and we can discuss
that then.

regards,

Peter.
