[PATCH v3 0/3] arm64: dts: qcom: eliza: Add ADSP and USB support

[Abel Vesa]

This series adds the ADSP and USB related description for the Qualcomm
Eliza platform.

The SoC dtsi gains the ADSP remoteproc node and its communication
dependencies, including IPCC, SMP2P and the AOSS QMP channel. It also
describes the USB controller, the SNPS eUSB2 PHY and the USB3/DP QMP
combo PHY.

The board dts then enables the ADSP and USB stack on the Eliza MTP,
including the Type-C connector graph, PMIC GLINK integration and the
PM7550BA eUSB2 repeater.

The following patchsets document all necessary bindings:

Changes in v3:
- Rebased on next-20260508.
- Picked up Konrad's and Krzysztof's R-b and T-b tags which I forgot
  to fetch from v1 thread.
- Link to v2: https://patch.msgid.link/20260504-eliza-adsp-usb-v2-0-18e0b0b0407f@oss.qualcomm.com

Changes in v2:
- Rebased on next-20260430.
- Changed the HS PHY ref clock to TCSR_USB2_CLKREF_EN, as suggested by
  Konrad.
- Changed the HS PHY VDD supply to L7K instead of L2B.
- Dropped the dr_mode property from the controller for MTP board, as
  suggested by Konrad.
- Re-worded the cover with more info and updated the bindings required
  patchsets list.
- Link to v1: https://patch.msgid.link/20260331-eliza-adsp-usb-v1-0-d8a251be20c3@oss.qualcomm.com

[PATCH v3 1/3] arm64: dts: qcom: eliza: Describe the ADSP and USB related nodes

[Abel Vesa]

Describe the ADSP remoteproc node along with its dependencies, including
the IPCC mailbox, AOSS QMP and SMP2P links used for communication.

The Eliza SoC features a USB 3.1 Gen 2 controller connected to a QMP
combo PHY and an SNPS eUSB2 PHY. Describe them.

[PATCH v3 2/3] arm64: dts: qcom: Add Eliza-specific PM7750BA dtsi

[Abel Vesa]

On Eliza, the SPMI arbiter supports multiple bus masters, requiring
explicit selection of the master for each PMIC.

The existing PM7750BA dtsi does not provide a way to describe this,
so introduce an Eliza-specific variant with the appropriate bus
configuration.

This duplication is required due to hardware differences in how the
SPMI bus is exposed on this platform.

Was wondering if it might be easier to do something like this instead?

eliza-mtp.dts:
```
#define PM7550BA_SPMI_BUS &spmi_bus0
```

pm7550ba.dtsi:
```
PM7550BA_SPMI_BUS {
    pm7550ba: pmic@7 {
...
    };

That way you wouldn't have to duplicate entire file, but don't know if this has
already been discussed previously.

The suggestion for duplication came from here:

[PATCH v3 3/3] arm64: dts: qcom: eliza-mtp: Enable USB and ADSP support

[Abel Vesa]

The Eliza MTP features a single USB Type-C port. Its USB 2.0 lines are
routed through an eUSB2 repeater provided by the PM7750BA PMIC.

Describe the port and repeater, and enable the USB controller and PHYs.

Also specify the ADSP firmware and enable the remoteproc.

Why mention something that is part of a different support ?

In fact, there is no repeater, there is only an SBU MUX.

Which will only be brought in along with DP audio, IIUC.

Repeaters are a part of the USB chain as they also affect USB signals.

Great, then there is no need to mention anything.
