[PATCH v2 0/3] Initial QMP USB PHY support for SM8475

[PATCH v2 0/3] Initial QMP USB PHY support for SM8475

[Esteban Urrutia via B4 Relay]

Based on the following patch:
[1] https://lore.kernel.org/all/20260711-sm8450-qol-qmp-v2-2-d14353bd6ff4@proton.me/

This series adds support for the QMP USB PHY found in the SM8475 SoC.
The initialization sequence varies noticeably when compared to the one used
in the SM8450 SoC, hence the need to add support for this PHY.

Changes in v2:
- Split series in subseries (pcie, usbss)
  - Sorry, it should have been like this from the start!
- Add notice about base commit
  - Reason why calibrate_dp_phy is not present
- Modify referenced swing and pre-emphasis tables
- Move v1 PLL tables to SM8475 support patch
  - Warnings are generated at build time otherwise
- Link to v1: https://patch.msgid.link/20260714-sm8475-bup-v1-0-b2871be2b4ec@proton.me

[PATCH v2 1/3] dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp-phy: Add SM8475 QMP PHY

[Esteban Urrutia via B4 Relay]

From: Esteban Urrutia <esteuwu@proton.me>

SM8450 init sequence for this PHY varies significantly and can't be used in
SM8475.
Add bindings for the PHY found in this SoC.

[PATCH v2 2/3] phy: qcom: qmp-combo: Specify PLL version in qmp_v6_dp_serdes_tbl structs

[Esteban Urrutia via B4 Relay]

From: Esteban Urrutia <esteuwu@proton.me>

Two versions of PLLs for v6 PHYs exist: v1 and v1.1.
These tables only cover v1.1 PLLs.
For serdes, the difference between v1 and v1.1 PLLs is the value written to
the BG_TIMER register.
This register is set to 0x0e for v1 PLLs and 0x0a for v1.1 PLLs.
As reference, SM8550 and SM8650 SoCs use v1.1 PLLs.
For RBR/HBR/HBR2/HBR3, most values change.
Make this distinction clear to avoid confusion when adding support for SoCs
making use of v1 PLLs.

[PATCH v2 3/3] phy: qcom: qmp-combo: Add SM8475 support

[Esteban Urrutia via B4 Relay]

From: Esteban Urrutia <esteuwu@proton.me>

Has been tested with the following capabilities:
- USB Type-C at 10Gb/s
- DP Alt Mode, using HBR2
- USB Type-C at 480Mb/s + DP Alt Mode, using HBR2

RX and PCS USB tables had to be added, while serdes, TX and PCS tables were
reused from other SoCs.
Since SM8475 uses a v1 PLL, add and use v1 PLL tables as well.

phy: qcom: qmp-combo: Add SM8475 support

This commit adds support for the SM8475 SoC to the QMP combo PHY driver,
including RX and PCS USB tables, and new v1 PLL tables.

[Severity: Medium]
Does this configuration intentionally omit the .calibrate_dp_phy callback?

Other DP configurations in this driver, such as sm8550_usb3dpphy_cfg, assign
this to qmp_v4_calibrate_dp_phy. Without it, when DP Alt Mode link training
fails, qmp_combo_dp_calibrate() will see a NULL callback and silently return 0.

This skips the DP AUX PHY calibration process which cycles through different
AUX configuration settings. Could this cause DisplayPort Alt Mode to fail
negotiating with some monitors or cables?
