There is a newer version of this series
[PATCH v3 3/4] arm64: dts: qcom: Add PURWA-IOT-SOM platform
Posted by YijieYang 3 weeks, 6 days ago 
From: Yijie Yang <yijie.yang@oss.qualcomm.com>

The PURWA-IOT-SOM is a compact computing module that integrates a System
on Chip (SoC) — specifically the x1p42100 — along with essential
components optimized for IoT applications. It is designed to be mounted on
carrier boards, enabling the development of complete embedded systems.

Make the following peripherals on the SOM enabled:
- Regulators on the SOM
- Reserved memory regions
- PCIe3, PCIe4, PCIe5, PCIe6a
- USB0 through USB6 and their PHYs
- ADSP, CDSP
- Graphic

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?

video should leverage most from hamoa, infact Wangao have validated iris 
on purwa very recently.

+Wangao to list the changes he made to bring it up
