dt-bindings: mediatek: Replace Tinghan Shen in maintainers

2026-02-04T02:58:11+00:00

Emails to Tinghan Shen bounce permanently with "550 Relaying mail to tinghan.shen@mediatek.com is not allowed (in reply to RCPT TO command)", so switch to AngeloGioacchino Del Regno - Mediatek SoC platform maintainer.

Merge branch '20260105-kvmrprocv10-v10-0-022e96815380@oss.qualcomm.com' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into rproc-next

2026-01-14T03:44:18+00:00

Merge the support for loading and managing TustZone-based remote processors found in the Qualcomm Glymur platform from a shared topic branch, as it's a mix of qcom-soc and remoteproc patches.

dt-bindings: remoteproc: qcom,pas: Add iommus property

2026-01-13T18:14:33+00:00

On most Qualcomm platforms, the Qualcomm Hypervisor Execution Environment (QHEE) is either used as a standalone hypervisor or co-exists as a module with the Gunyah hypervisor. When QHEE is present, it configures firmware streams for remote processors. If QHEE is not available, the operating system must perform these configurations instead and for that remote processor firmware stream should be presented to the operating system. To support this, add the iommus property as an optional property for PAS-supported devices.

dt-bindings: remoteproc: Add HSM M4F core on TI K3 SoCs

2026-01-07T15:32:04+00:00

Some of the TI K3 family of SoCs have a HSM (High Security Module) M4F core in the Wakeup Voltage Domain which could be used to run secure services like Authentication. Add the device tree bindings document for this HSM M4F core. The added example illustrates the DT node for the HSM core present on K3 J722S SoC.

dt-bindings: remoteproc: qcom,sm8550-pas: Drop SM8750 ADSP from if-branch

2026-01-03T15:59:53+00:00

The binding for SM8750 ADSP PAS uses SM8550 ADSP as fallback, thus "if:then:" block with "contains:" and the fallback does not need to mention qcom,sm8750-adsp-pas.

dt-bindings: remoteproc: qcom,adsp: Allow cx-supply on qcom,sdm845-slpi-pas

2026-01-03T15:20:28+00:00

One SDM845 board uses cx-supply, which is not allowed by the bindings, as reported by dtbs_check: sdm845-samsung-starqltechn.dtb: remoteproc@5c00000 (qcom,sdm845-slpi-pas): Unevaluated properties are not allowed ('cx-supply' was unexpected) The SDM845 SLPI binding already allows lcx and lmx domains, thus the cx-supply seems like a fake name for something else, e.g. some enable pin. The qcom_q6v5_pas.c driver parses cx-supply, so it is an established ABI, therefore document it for this device only.
