Pull remoteproc updates from Bjorn Andersson: "rproc-virtio device names are now auto generated, to avoid conflicts between remoteproc instances. The imx_rproc driver is extended with support for communicating with and attaching to a running M4 on i.MX8QXP, as well as support for attaching to the M4 after self-recovering from a crash. Support is added for i.MX8QM and mailbox channels are reconnected during the recovery process, in order to avoid data corruption. The Xilinx Zynqmp firmware interface is extended and support for the Xilinx R5 RPU is introduced. Various resources leaks, primarily in error paths, throughout the Qualcomm drivers are corrected. Lastly a fix to ensure that pm_relax is invoked even if the remoteproc instance is stopped between a crash is being reported and the recovery handler is scheduled" * tag 'rproc-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (25 commits) remoteproc: core: Do pm_relax when in RPROC_OFFLINE state remoteproc: qcom: q6v5: Fix missing clk_disable_unprepare() in q6v5_wcss_qcs404_power_on() remoteproc: qcom_q6v5_pas: Fix missing of_node_put() in adsp_alloc_memory_region() remoteproc: qcom_q6v5_pas: detach power domains on remove remoteproc: qcom_q6v5_pas: disable wakeup on probe fail or remove remoteproc: qcom: q6v5: Fix potential null-ptr-deref in q6v5_wcss_init_mmio() remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev() remoteproc: sysmon: Make QMI message rules const drivers: remoteproc: Add Xilinx r5 remoteproc driver firmware: xilinx: Add RPU configuration APIs firmware: xilinx: Add shutdown/wakeup APIs firmware: xilinx: Add ZynqMP firmware ioctl enums for RPU configuration. arm64: dts: xilinx: zynqmp: Add RPU subsystem device node dt-bindings: remoteproc: Add Xilinx RPU subsystem bindings remoteproc: core: Use device_match_of_node() remoteproc: imx_rproc: Correct i.MX93 DRAM mapping remoteproc: imx_rproc: Enable attach recovery for i.MX8QM/QXP remoteproc: imx_rproc: Request mbox channel later remoteproc: imx_rproc: Support i.MX8QM remoteproc: imx_rproc: Support kicking Mcore from Linux for i.MX8QXP ...
