* [PATCH] phy: qualcomm: qmp-combo: update DP PHY PLL programming on Glymur

Mahadevan P
The existing DP PHY PLL and AUX configuration for the Glymur platform
does not fully follow the Hardware Programming Guide requirements for
DP over Type-C, which results in DP link bring-up failures.
Update the DP PHY programming sequence and PLL-related register
settings to align with the latest HPG recommendations. With this
change, DP link training completes successfully on Glymur-based
platforms.
Fixes: d10736db98d2 ("phy: qualcomm: qmp-combo: Add DP offsets and settings for Glymur platforms")

Tested on a Glymur CRD platform with two DisplayPorts over USB Type-C:
- Link training completes successfully
- Display comes up at expected resolutions

OK, that's what I wanted to hear. And that's what should not be done,
You should not have a separate node for the same hardware. First, DTC
will give you a W=1 warning, although warning itself should be moved to
W=2.
Second, the warning tells important story - same hardware is described
twice.
You only need phy_3a and phy_3b, so only two in total.
phy_3a could have resources of phy_3b OR could have a phandle to
companion (follower) phy to fetch resources from it. I don't know yet
which choice is better, though.
Best regards,
Krzysztof

I guess this was missed for Linux v7.1. If you don't have any concerns
can you pick this up for v7.2 once v7.1-rc1 is out?

Neither this, nor try from 2011, nor any future try should be accepted,
because it creates impression IS_ERR_OR_NULL is somehow okay. No, it is
not okay, it is a discouraged pattern leading to less readable and
maintainable code. We should not have therefore any tools suggesting
usage of IS_ERR_OR_NULL, because people will be converting poor code
into that, instead of fixing that poor code.

IS_ERR_OR_NULL is simply discouraged, but beside of code preference, you
just added bug here. This is clearly not equivalent and you emit warn on
perfectly valid case!

SC8180X will need changes, but it's already incorrect so this

Obviously we cannot even keep order of nodes when creating a new DTSI
file from scratch.
But adding @f00000 after @1c10000 makes even less sense, regardless how
bad existing code is. Don't make it worse!

No, but don't add nodes randomly or following the previous broken order.

The existing PCIe/PHY nodes are not strictly ordered by address. Current
order is:
- pcie4: pci@1bf0000
- pcie4_phy: phy@1bf6000
- pcie5: pci@1b40000
- pcie5_phy: phy@1b50000
- pcie6: pci@1c00000
- pcie6_phy: phy@1c06000
- pcie3b: pci@1b80000
- pcie3a: pci@1c10000 (added in this patch)
- pcie3a_phy: phy@f00000 (added in this patch)

It is not the same as the 5x4 PHY. In DT, we model three PHY nodes:
phy_3a (1x4), phy_3b (1x4), and a separate phy_1x8 node for x8 mode.

Okay, I will focus on describing the required resources. Is the
description below clearer?
Glymur has two physical Gen5x4 PCIe PHY blocks: pcie3a phy and pcie3b phy.
Besides the independent 2x4 topology, Glymur also supports an x8 topology
that is described as a dedicated 1x8 PHY DT node. In this topology, the
x8 PHY uses resources from both PHY blocks: pcie3a (leader) and pcie3b
(follower) resources.
Add qcom,glymur-qmp-gen5x8-pcie-phy to describe this x8 PHY node and
document its extra required resources:
- pcie3b PHY aux clock (phy_b_aux)
- pcie3b PHY power domain
- pcie3b PHY BCR/NOCSR resets
The phy_b_aux clock is used as the 6th clock instead of pipediv2,
requiring the clock-names enum to be extended to support both
[phy_b_aux, pipediv2] options at index 5. This follows the existing
pattern used for [rchng, refgen] clocks at index 3.

Commit 81af9e40e2e4 ("phy: qcom: qmp-ufs: Fix SM8650 PCS table for Gear 4")
moved QPHY_V6_PCS_UFS_PLL_CNTL register configuration from the shared
sm8650_ufsphy_g5_pcs table to the SM8650-specific sm8650_ufsphy_pcs base
table to fix Gear 4 operation on SM8650.
However, this change inadvertently broke kaanapali and SM8750 SoCs
which also rely on the shared sm8650_ufsphy_g5_pcs table for Gear 5
configuration but use their own sm8750_ufsphy_pcs base table. After the
change, kaanapali PHYs are left without the required PLL_CNTL = 0x33
setting, causing the PHY PLL to remain at its hardware reset default
value, preventing PLL lock and resulting in DME_LINKSTARTUP timeouts.
Fix this by adding the missing QPHY_V6_PCS_UFS_PLL_CNTL = 0x33 entry
to the sm8750_ufsphy_pcs table, mirroring what the original commit
already did for sm8650_ufsphy_pcs.

I personally think this is the cleanest approach, at least from the dt-description
standpoint.
For combo mode..
I forgot what the conclusion was on the sensor-to-(CAMSS vs CSIPHY) connections
or whether there was one, but in any case, I think that data-lanes and bus-type
could be aggregated across each PHY instance and the final operating mode could
be chosen based on that, at runtime by the driver that managed all this (say,
via phy_configure())

Do you describe PCI3A or PCI3B or something combined PCI3?

That's the same device as 5x4, no? One device, one compatible and this
suggests you will have three PCI phys in the DT - two 5x4 and one 5x8?

And now I doubt that all the changes here are for duplicated node.
Maybe just the commit msg is confusing and instead of describing some
node which combines two other phys just say what device is here being
described.

Hi Vinod,
Just a gentle ping on this patch series.
Since you reviewed the previous version, I wanted to check if you might have
a chance to take a look at this one when time permits.
Any feedback would be appreciated.

... and valid uses of IS_ERR_OR_NULL are rare as hen teeth.
Most of those are "I'm not sure how this function returns an
error, let's use that just in case".
Please, do not introduce more of that crap.

* [PATCH v1] phy: eswin: Fix incorrect error check in probe()
From: Yulin Lu @ 2026-04-13 7:00 UTC (permalink / raw)
To: vkoul, neil.armstrong, linux-phy, linux-kernel
Cc: linmin, ningyu, Yulin Lu, Dan Carpenter
devm_ioremap() returns NULL on failure, not an ERR_PTR.
Using IS_ERR() to check the return value is incorrect.
Fix this by checking for NULL and returning -ENOMEM.
Fixes: 67ee9ccaa34a ("phy: eswin: Create eswin directory and add EIC7700 SATA PHY driver")
Reported-by: Dan Carpenter <error27@gmail.com>
Closes: https://lore.kernel.org/linux-phy/adjNbuWoc1B-3Ok1@stanley.mountain/
