[PATCH 0/6] Add PPE device tree node for Qualcomm IPQ SoC

[PATCH 0/6] Add PPE device tree node for Qualcomm IPQ SoC

[Luo Jie]

The PPE(packet process engine) hardware block is supported by Qualcomm
IPQ platforms, such as IPQ9574 and IPQ5332. The PPE includes the various
packet processing modules such as the routing and bridging flow engines,
L2 switch capability, VLAN and tunnels. Also included are integrated
ethernet MAC and PCS(uniphy), which is used to connect with the external
PHY devices by PCS.

This patch series enables support for the following DTSI functionality
for Qualcomm IPQ9574 and IPQ5332 chipsets. 

1. Add PPE (Packet Processing Engine) HW support

2. Add IPQ9574 RDP433 board support, where the PPE is connected
   with qca8075 PHY and AQ PHY.

3. Add IPQ5332 RDP441 board support, where the PPE is connected
   with qca8386 and SFP

PPE DTS depends on the NSSCC clock driver below, which provides the
clocks for the PPE driver.

[PATCH 1/6] arm64: dts: qcom: ipq9574: Add PPE device tree node

[Luo Jie]

The PPE device tree node includes the PPE initialization configurations
and UNIPHY instance configuration.

Ther are 3 UNIPHYs(PCS) on the platform ipq9574, which register the
clock provider to output the clock for PPE port to work on the different
link speed.

[PATCH 2/6] arm64: dts: qcom: ipq5332: Add PPE device tree node

[Luo Jie]

The PPE device tree node includes the PPE initialization configurations
and the UNIPHY(PCS) instance configurations.

There are two UNIPHYs in ipq5332 platform, which provide the root clock
to the PPE port to work on the different link speed.

None of these describe (or even use) the compatible in the first
patch of this series ("qcom,ipq9574-ppe"). I didn't check the
subsequent ones, as I assume it's the same situtation, so this
is a NAK.

qcom is definitely not a generic name.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation


> +			compatible = "qcom,ipq9574-ppe";

I don't see this documented. I don't see reference to posted bindings.

Please run scripts/checkpatch.pl and fix reported warnings. Some
warnings can be ignored, but the code here looks like it needs a fix.
Feel free to get in touch if the warning is not clear.

Ignoring this warning is a sign you don't really check your patches
before sending.

Put after reg.

> +			status = "okay";

Drop

All of above comments apply to your entire patchset and all places.

Looking at code further, it does not look like suitable for mainline,
but copy of downstream code. That's not what we expect upstream. Please
go back to your bindings first. Also, I really insist you reaching out
to other folks to help you in this process.

Best regards,
Krzysztof

Subject: drop "device tree", it is obvious. Commit msg: say something
more instead of copying the subject. Or better squash the entire patch.

This wasn't tested...

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/

Nope, DTS does not define soc nodes.

Why is this soc? Where is the MMIO address?

Eh... We talk now about basics: please don't post downstream code, but
first clean it up from all the junk. All the basic issues which you have
in downstream and which we do not accept upstream.

I do not believe that this code passed internal review.

NAK.

DTS cannot depend on clock drivers. Maybe you meant that it depends on
NSSCC clock controller DTS changes, which would be fine. However
depending on drivers is neither necessary nor allowed.

I don't know why i'm asking this, because i don't really expect a
usable answer. What sort of MUX is this? Should you be using one of
the muxes in drivers/net/mdio/mdio-mux-* or something similar?

Ok, will update to use a generic name in the link, Thanks for the

The DT bindings patch was part of the driver series as below. This
property was documented in the DT bindings patch. Attaching it to DTSI 
series should make it more clear. If this is fine, I will update the 
DTSI series with the DT bindings patch.

We have run the checkpatch.pl on the whole patch series including this
device tree patch set together with PPE driver patch set.
As mentioned above, I will add the DT bindings patch into the DTS
series. This should help with the checkpatch issue.

Sorry for the confusion, the pin nodes are for the MDIO and MDC, these
PINs are used by the dedicated hardware MDIO block in the SoC. I will 
update the node name from mux_0 to MDC, mux_1 to MDIO, to make it clear. 
The driver for this node is drivers/net/mdio/mdio-ipq4019.c, it is not 
related to the mdio-mux-* code.

This will cause even more confusion, as there will be two instances of
the dt-bindings patch. One in the driver patchset, another one in the
DT changes. You just have to specify the dependencies in the cover
letter. Another option is to wait for the bindings + driver to be
accepted, then send the DTSI changes (and again, specify the
dependency).

From the first glance, the bindings do not follow upstream principles.
You have all the settings (tdm, port config, etc) in the DT, while
they should instead go to the driver. Well, unless you expect that the
board might need to override them.

Have you read Documentation/devicetree/bindings/pinctrl/qcom,ipq5332-tlmm.yaml
? Have you validated your DTSI files against DT schema? How many
warnings will you observe if you rename the mux_0 node to MDC?

So these is all about pinmux.

When you say:
> PINs are used by the dedicated hardware MDIO block in the SoC

do you actually mean:

PINs are used by the two dedicated hardware MDIO blocks in the SoC.

You have two sets of mdio/mdc configurations here, so i assume there
are two MDIO hardware blocks, each being an MDIO bus master.

NAK. Run dtbs_check tests on your DTS first.

Thanks Dmitry for the suggestions.


As per the ongoing discussion on this series, we will hold off this DTS 
patch series for some time. We will update the cover letter of the DTSI 
series to point to the below driver series as a dependency, when we 
resume the series.

Hi Dmitry,
The TDM configuration varies per SoC type, since the ethernet port 
capabilities of the SoCs vary. So we will have two different TDM 
configurations for IPQ5332 and IPQ9574 SoC. The driver also will
need to support future SoC, so we choose to configure this from the 
DTSI. The same reason applies to the port scheduler config as well.

Thanks for review comments.

Your statements here confirm Dmitry suggestion, so these are not board
specific and should go to the driver. Please read again Dmitry's sentences.

The DT binding file was included in the PPE driver series, which
documents the compatible string.

https://lore.kernel.org/netdev/20240110142428.52026d9e@kernel.org/

I will hold off this DTSI patch series for now as per discussion in the
series. When the series is resumed later, I will mention the link of PPE 
driver patch series in the cover letter, when updating this DTS patch 
series. Sorry for this confusion caused.

These two patches are for adding the PPE port related configuration 
nodes (such as port speed, interface mode and MDIO address) which are 
board specific. RDP441 and RDP433 are two different board types. Perhaps
the title of the patches are not clear enough. I will update the title
to make it clear when the patch series resumes.

Yes, this DTSI series depends on the NSSCC clock controller DTS patches 
which are referred to in the cover letter. I will rectify the cover

If it differs from SoC to SoC only, it goes to the driver. Point. No other options. Thank you.

This part looks extremely wrong to me. If the reg is 16, then it should be @16 as well. You should have got a warning here.

Sorry for this error, we will follow the DTSI validation process and

There are two MDIO hardware blocks on IPQ5332 SoC. One is
for the MDIO bus master(gpio27, 28), which is for accessing the MDIO
slave devices(like PHY device). The mdio-ipq4019.c driver enables
this MDIO bus master.

Another one is the MDIO slave(gpio25, 26), which is dedicated
for receiving the back pressure signal from the connected Ethernet 
switch device QCA8386.

There is a MDIO master block integrated in QCA8386 switch device, this
integrated MDIO master is dedicated for generating the back
pressure signal to IPQ5332 SoC.

This MDIO slave block of IPQ5322 just needs to configure these PIN
mux for MDC and MDIO PINs. No additional driver is needed for this MDIO
slave block of IPQ5332.

So there is a proprietary protocol running over the MDIO bus? And its
completely implemented in hardware in the slave block? Is this even
MDIO? Does it use c22 or c45 bus transactions? How is the slave
address configured, or is that also hard coded?

Hi Andrew,
Yes, this is a custom HW mechanism using the MDIO C22 frame, to enable 
back pressure from the QCA8386 switch to the IPQ5332 SoC. The slave 
block in the IPQ5332 SoC implements the back pressure function. There is 
no configuration for the MDIO slave address of IPQ5332 required, since 
the connection is one to one between slave and master.

However upon further review, we believe this node definition belongs to
the board DTS file, since the switch configuration is a board property.
We will move out this MDIO slave config from the patch series to
avoid the confusion. We will also rename the node from 'mdio0-state' to 
'backpressure-state' to make this clear.

Thanks.

OK, I will remove the soc node in the DTS file. SFP node should not be

Sure, SoC node should not be required. I will remove the soc node.

Sure, we will update the driver to configure the TDM depending on the 
SoC need.
