[PATCH v3 0/4] Initial patch set for PURWA-IOT-EVK

[PATCH v3 0/4] Initial patch set for PURWA-IOT-EVK

[YijieYang]

From: Yijie Yang <yijie.yang@oss.qualcomm.com>

Introduce the device tree, DT bindings, and driver updates required to enable
the bring-up of the PURWA-IOT-EVK evaluation board. Focus is on two key
hardware components:

PURWA-IOT-SOM — A compact System-on-Module integrating the SoC, GPIOs, and
PMICs. Designed for modularity, it can pair with various carrier boards to
support diverse use cases.

PURWA-IOT-EVK — A carrier board tailored for IoT scenarios, providing
essential peripherals such as UART, on-board PMICs, and USB components.

Together, these components form a flexible and scalable platform. Initial
functionality is achieved through proper device tree configuration and driver
support.

The PURWA-IOT-EVK/SOM shares most of its hardware design with
HAMOA-IOT-EVK/SOM, differing primarily in the BOM. Consequently, the DTS files
are largely similar. Both platforms belong to Qualcomm’s IQ-X family. For more
details on the IQ-X series, see:
https://www.qualcomm.com/internet-of-things/products/iq-x-series

Hardware differences between HAMOA-IOT and PURWA-IOT:
- Display — PURWA uses a different number of clocks and frequency compared to
  HAMOA.
- GPU — PURWA integrates a different GPU.
- USB0 — PURWA uses a PS8833 retimer, while HAMOA employs an FSUSB42 as the
  SBU switch.

Features added and enabled:
- UART
- On-board regulators
- Regulators on the SOM
- PMIC GLINK
- USB0 through USB6 and their PHYs
- Embedded USB (eUSB) repeaters
- USB Type-C mux
- PCIe3, PCIe4, PCIe5, PCIe6a
- Reserved memory regions
- Pinctrl
- NVMe
- ADSP, CDSP
- WLAN, Bluetooth (M.2 interface)
- USB DisplayPort and eDP
- Graphics
- Audio

[PATCH v3 2/4] firmware: qcom: scm: Allow QSEECOM on PURWA-IOT-EVK

[YijieYang]

From: Yijie Yang <yijie.yang@oss.qualcomm.com>

Add the Purwa-IoT-EVK board to the list to enable access to EFI variables.

Guarantee that subsystems relying on SCM services can access secure-world
features. This change improves reliability and prevents missing
functionality or boot-time issues by making service availability explicit.

[PATCH v3 4/4] arm64: dts: qcom: Add base PURWA-IOT-EVK board

[YijieYang]

From: Yijie Yang <yijie.yang@oss.qualcomm.com>

The PURWA-IOT-EVK is an evaluation platform for IoT products, composed of
the Purwa IoT SoM and a carrier board. Together, they form a complete
embedded system capable of booting to UART.

PURWA-IOT-EVK uses the PS8833 as a retimer for USB0, unlike HAMOA-IOT-EVK.
Meanwhile, USB0 bypasses the SBU selector FSUSB42. As a result, the glink
topology differs from that of HAMOA-IOT-EVK.

Make the following peripherals on the carrier board enabled:
- UART
- On-board regulators
- USB Type-C mux
- Pinctrl
- Embedded USB (EUSB) repeaters
- NVMe
- pmic-glink
- USB DisplayPorts
- Bluetooth
- WLAN
- Audio
- PCIe ports for PCIe3 through PCIe6a

Purwa has a slightly different Iris hw version (8.1.2 on Hamoa, 8.1.11 on Purwa)
which I would assume is slighly weaker, plus there's probably a freqtbl change

Let's take this as-is and enable it later

+Vikash, Dikshita this seems like a really low-hanging fruit, could you take
a look at Purwa support in Iris?

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: 377054868ffa544991cc491ecc4016589fc58565 (use --merge-base to override)

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

New warnings running 'make CHECK_DTBS=y for arch/arm64/boot/dts/qcom/' for 20260113-purwa-v3-0-16eefacbdce9@oss.qualcomm.com:

What I’m referring to here is that the graph composed of glink nodes and

Then:

As a result, implement corresponding changes to OF graph connections
between USB-C connectors and USB host controllers.

Or just drop this phrase completely.
