Pull remoteproc updates from Bjorn Andersson: "This introduces a new "detached" state for remote processors that are deemed to be running at the time Linux boots and the infrastructure for "attaching" to these. It then introduces the support for performing this operation for the STM32 platform. The coredump functionality is moved out from the core file and gains support for an optional mode where the recovery phase awaits the notification from devcoredump that the dump should be released. This allows userspace to grab the coredump in scenarios where vmalloc space is too low for creating a complete copy of the coredump before handing this to devcoredump. A new character device based interface is introduced to allow tying the stoppage of a remote processor to the termination of a user space process. This is useful in situations when such process provides crucial resources/operations for the firmware running on the remote processor. The Texas Instrument K3 driver gains support for the C66x and C71x DSPs. Qualcomm remoteprocs gains support for stashing relocation information in IMEM, to aid post mortem debugging and the crash notification mechanism is generalized to be reusable in cases where loosely coupled drivers needs to know about the status of a remote processor. One such example is the IPA hardware block, which is jointly owned with the modem and migrated to this improved interface. It also introduces a number of bug fixes and debug improvements for the Qualcomm modem remoteproc driver. And it cleans up the inconsistent interface for remoteproc drivers to implement power management" * tag 'rproc-v5.9' of git:// (56 commits) remoteproc: core: Register the character device interface remoteproc: Add remoteproc character device interface remoteproc: kill IPA notify code net: ipa: new notification infrastructure remoteproc: k3-dsp: Add support for C71x DSPs dt-bindings: remoteproc: k3-dsp: Update bindings for C71x DSPs remoteproc: k3-dsp: Add support for L2RAM loading on C66x DSPs remoteproc: k3-dsp: Add a remoteproc driver of K3 C66x DSPs dt-bindings: remoteproc: Add bindings for C66x DSPs on TI K3 SoCs remoteproc: k3: Add TI-SCI processor control helper functions remoteproc: Introduce rproc_of_parse_firmware() helper dt-bindings: arm: keystone: Add common TI SCI bindings remoteproc: qcom_q6v5_mss: Remove redundant running state remoteproc: qcom: q6v5: Update running state before requesting stop remoteproc: qcom_q6v5_mss: Add modem debug policy support remoteproc: qcom_q6v5_mss: Validate modem blob firmware size before load remoteproc: qcom_q6v5_mss: Validate MBA firmware size before load rpmsg: update documentation remoteproc: qcom_q6v5_mss: Add MBA log extraction support remoteproc: Add coredump debugfs entry ...
