[PATCH v4 0/5] arm64: dts: qcom: Add Kalambo SoC and CRD

From: Gopikrishna Garmidi

Date: Fri Jul 31 2026 - 02:18:06 EST


Qualcomm Kalambo SoC is derived from Mahua SoC with CPU cluster 0
removed,leaving only cluster 1 present.

This series documents the board compatibles and adds the SoC and
Compute Reference Device (CRD) device trees. It also adds the Kalambo
compatible to the UBWC configuration table and allowlists the Kalambo
CRD for QSEECOM to enable access to efivars.

Changes in v4:
- Split PDC range <108 619 22> into <108 619 1> and <111 622 19> to skip
unconnected pins 109 and 110 on Kalambo. All other PDC ranges match Glymur.
- Rebased on next-20260729.
- Link to v3: https://patch.msgid.link/20260727-b4-kalambo-crd-v3-0-25280faceece@xxxxxxxxxxxxxxxx

Changes in v3:
- Delete and redefine the whole cpu-map via the /cpus label.
- pdp0_mbox: one reg entry per line and use '0x0' instead of '0'.
- Rebased on next-20260726.
- Picked up R-b tags.
- Link to v2: https://patch.msgid.link/20260722-b4-kalambo-crd-v2-0-32d4addc1ac9@xxxxxxxxxxxxxxxx
