My comments here apply to the other dts patch (P3/3) as well since the
integration appears to be identical between the two SoCs.

There are two power domains on this GPU and the SoC exposes both of
them; no reason to fall back to the single-domain scheme here.

I know the sysc driver declares the dependency of _B on _A, but the dts
shouldn't rely on that, so can we have:

   power-domains = <&sysc R8A7796_PD_3DG_A>, <&sysc R8A7796_PD_3DG_B>;
   power-domain-names = "a", "b";

> +			resets = <&cpg 112>;

Is this a reset line? Is it a clock? I see this pattern used throughout
the Renesas dts, but I'm just thinking how this will interact with the
powervr driver. The reset line is optional since some hardware
integrations manage it for us during the power-up/down sequences, which
appears to be the case here with the MSTP control (from my brief dig
through the Renesas TRM).

Related, see my comments on the bindings patch (P1/3) about how clocks
are wired up in this SoC.

Cheers,
Matt

Both SoCs fixed in V2 , which I will post in a few days , thanks !

This is a reset line. The MSTP controls both clocks and resets, but this 
particular phandle describes reset control.

As far as I can tell, the pvr_power.c toggles the IP reset after the IP 
clock were already enabled, so the IP should be correctly reset. What 
kind of problem do you expect ?

I tried to reply to that one, hopefully it makes some sense.

I think I'm just being paranoid about the weirdness (to me at least) of
having one device be treated as both clock and reset line. Assuming this
is tested as working, I'm okay with it, especially as it seems to be the
norm for Renesas.

Looks like we've figured it out there, thanks for your comments!

The combined clock/reset IP is not limited to renesas SoCs, there are 
other SoCs which do the same thing (Allwinner "ccu", Marvell PXA 
"soc_clocks" , nVidia Tegra "car", Qualcomm "gcc", Rockchip "cru", to 
name a few). Usually the registers which control clock and resets are 
shared in the same IP, but they control different (possibly related) 
signals in the SoC.

Likewise, thank you for sharing the clocking details.

I think this can just be renesas,r8a7796-gpu; most of the devices in the
dts for these SoCs appear to use the same pattern and the GPU is the
same in both.

You also need to add img,img-gx6250 to the appropriate conditional
blocks below here for the number of power domains (in this case, 2) and
clocks (that's more complicated).

These older GPUs always require three clocks (core, mem and sys), but
it's not immediately clear from the Renesas TRM how these are hooked up.
I can see three "clocks" connected (fig 23.2 in my copy, clock details
from fig 8.1b):

 - Clock ZGφ: Appears to be a core clock for the GPU (3DGE). That would
   make it our "core" clock.
 - Clock S2D1φ: Appears to be a core clock used on the AXI bus, making
   it our "sys" clock.
 - MSTP ST112: Appears to be a whole module on/off control of some
   description, and definitely doesn't align with the missing "mem"
   clock.

Do you have any further insights as to how Renesas have wired things up?

Cheers,
Matt

Not really, the 77960 and 77961 are different SoCs, that is why they 
each have different specific compatible. Of course, most drivers match 
on fallback compatible, since the IPs are mostly identical, see this:

$ git grep compatible.*7796 arch/arm64/boot/dts/renesas/r8a77961.dtsi
arch/arm64/boot/dts/renesas/r8a77961.dtsi:      compatible = 
"renesas,r8a77961";
arch/arm64/boot/dts/renesas/r8a77961.dtsi: 
compatible = "renesas,r8a77961-wdt",
arch/arm64/boot/dts/renesas/r8a77961.dtsi: 
compatible = "renesas,gpio-r8a77961",
...

$  git grep compatible.*7796 arch/arm64/boot/dts/renesas/r8a77960.dtsi
arch/arm64/boot/dts/renesas/r8a77960.dtsi:      compatible = 
"renesas,r8a7796";
arch/arm64/boot/dts/renesas/r8a77960.dtsi: 
compatible = "renesas,r8a7796-wdt",
arch/arm64/boot/dts/renesas/r8a77960.dtsi: 
compatible = "renesas,gpio-r8a7796",
arch/arm64/boot/dts/renesas/r8a77960.dtsi: 
compatible = "renesas,gpio-r8a7796",

I can turn the first entry into renesas,r8a7796-gpu to be consistent 
with the legacy 7796 name for 77960.

Which revision of the RM is that ? There should be some Rev.M.NP at the 
bottom of each page.

This should be 600-700 MHz clock on M3-W , so that sounds like a GPU 
core clock.

This should be 400 MHz AXI clock, but wouldn't that make it "mem" clock 
? I think this might be the clock which drives the AXI bus, used by the 
GPU to access data in DRAM ?

Maybe this is the "sys" clock, since it toggles the register interface 
clock on/off ?

Please see above, maybe that helps a bit ?

Please use "renesas,r8a7796-gpu" for R-Car M3-W, and
"renesas,r8a77961-gpu" for R-Car M3-W+.

Probably.

Note that both ZGφ and S2D1φ are always-on.
MSTP ST112 is the only gateable clock, and it is controlled through
the PM Domain and Runtime PM.

Works for me. I mistook the non-0 version as a generic name for both,
not realising it was just a legacy thing. My bad!

Yes, this is probably correct. I got my AXI interfaces mixed up – we
have both a manager interface for accessing memory (using the mem clock)
and a subordinate interface to expose to our registers (using the sys
clock). Here's the summary table from our system integration document:

   +-------+-------------------------+------------------------+
   | Clock | Modules Clocked         | Dependencies           |
   +-------+-------------------------+------------------------+
   | mem   | SLC / AXI Manager       | Run for all operations |
   | sys   | SOCIF / AXI Subordinate | Run for all operations |
   | core  | All                     | Run for all operations |
   +-------+-------------------------+------------------------+

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-20251013 (exact match)
 Base: tags/next-20251013 (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
