Merge tag 'rproc-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/…
…git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "The remoteproc repo is moved to a new path on git.kernel.org, to allow Mathieu push access to the branches. Support for the Mediatek MT8195 SCP was added, the related DeviceTree binding was converted to YAML and MT8192 SCP was documented as well. Amlogic Meson6, Meson8, Meson8b and Meson8m2 has an ARC core to aid in resuming the system after suspend, a new remoteproc driver for booting this core is introduced. A new driver to support the DSP processor found on NXP i.MX8QM, i.MX8QXP, i.MX8MP and i.MX8ULP is added. The Qualcomm modem and TrustZone based remoteproc drivers gains support for the modem in SC7280 and MSM8996 gains support for a missing power-domain. Throughout the Qualcomm drivers, the support for informing the always-on power coprocessor about the state of each remoteproc is reworked to avoid complications related to our use of genpd and the system suspend state. Lastly a number of small fixes are found throughout the drivers and framework" * tag 'rproc-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (39 commits) remoteproc: Remove vdev_to_rvdev and vdev_to_rproc from remoteproc API remoteproc: omap_remoteproc: simplify getting .driver_data remoteproc: qcom_q6v5_mss: Use devm_platform_ioremap_resource_byname() to simplify code remoteproc: Fix a memory leak in an error handling path in 'rproc_handle_vdev()' remoteproc: Fix spelling mistake "atleast" -> "at least" remoteproc: imx_dsp_rproc: mark PM functions as __maybe_unused remoteproc: imx_dsp_rproc: Correct the comment style of copyright dt-bindings: dsp: fsl: Update binding document for remote proc driver remoteproc: imx_dsp_rproc: Add remoteproc driver for DSP on i.MX remoteproc: imx_rproc: Add IMX_RPROC_SCU_API method remoteproc: imx_rproc: Move common structure to header file rpmsg: char: Remove useless include remoteproc: meson-mx-ao-arc: fix a bit test remoteproc: mss: q6v5-mss: Add modem support on SC7280 dt-bindings: remoteproc: qcom: Update Q6V5 Modem PIL binding remoteproc: qcom: pas: Add SC7280 Modem support dt-bindings: remoteproc: qcom: pas: Add SC7280 MPSS support remoteproc: qcom: pas: Use the same init resources for MSM8996 and MSM8998 MAINTAINERS: Update remoteproc repo url dt-bindings: remoteproc: k3-dsp: Cleanup SoC compatible from DT example ...

|
|
||
| description: | ||
| Amlogic Meson6, Meson8, Meson8b and Meson8m2 SoCs embed an ARC core | ||
| controller for always-on operations, typically used for managing | ||
| system suspend. Meson6 and older use a ARC core based on the ARCv1 | ||
| ISA, while Meson8, Meson8b and Meson8m2 use an ARC EM4 (ARCv2 ISA) | ||
| core. | ||
