[PATCH v3 3/5] arm64: dts: qcom: Add Shikra CQ2390M SoM platform
From: Komal Bajaj
Date: Fri May 22 2026 - 14:22:03 EST
Add device tree include for the CQ2390M variant of the Shikra
System-on-Module, a compact compute module integrating the Shikra SoC
and PMIC for IoT applications, designed to mount on carrier boards.
- shikra-cqm-som.dtsi: Retail SoM with modem (PM4125 and PM8005 PMIC)
The DTSI includes the common shikra.dtsi, adds PM4125 and PM8005 PMIC
regulator definitions specific to this variant.
