Merge tag 'rproc-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/…
…git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This introduces support for controlling the TI PRU, adds hooks for remoteproc drivers to override the default ELF based coredump format, introduces a library function for coredumps using named sections (aka the Qualcomm "minidump" format). It also fixes a problem with inconsistent notifications sent by the Qualcomm sysmon driver to the remote processors and it migrates the Qualcomm MSS driver to use power-domains for resources that aren't actually regulators. Lastly it contains a number of fixes for minor bugs and build warnings throughout the drivers" * tag 'rproc-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (47 commits) remoteproc/mediatek: read IPI buffer offset from FW remoteproc/mediatek: unprepare clk if scp_before_load fails remoteproc: qcom: Fix potential NULL dereference in adsp_init_mmio() remoteproc/mediatek: Fix kernel test robot warning remoteproc: k3-dsp: Fix return value check in k3_dsp_rproc_of_get_memories() remoteproc: qcom: pas: fix error handling in adsp_pds_enable remoteproc: qcom: fix reference leak in adsp_start remoteproc: q6v5-mss: fix error handling in q6v5_pds_enable remoteproc/mtk_scp: surround DT device IDs with CONFIG_OF remoteproc: qcom: Add minidump id for sm8150 modem remoteproc: qcom: Add capability to collect minidumps remoteproc: coredump: Add minidump functionality remoteproc: core: Add ops to enable custom coredump functionality remoteproc/mediatek: change MT8192 CFG register base remoteproc: pru: Add support for various PRU cores on K3 J721E SoCs remoteproc: pru: Add support for various PRU cores on K3 AM65x SoCs remoteproc: pru: Add pru-specific debugfs support remoteproc: pru: Add support for PRU specific interrupt configuration remoteproc: pru: Add a PRU remoteproc driver dt-bindings: remoteproc: Add binding doc for PRU cores in the PRU-ICSS ...

| title: TI Programmable Realtime Unit (PRU) cores | ||
|

||
| description: | | ||
| Each Programmable Real-Time Unit and Industrial Communication Subsystem | ||
| (PRU-ICSS or PRUSS) has two 32-bit load/store RISC CPU cores called | ||
| Programmable Real-Time Units (PRUs), each represented by a node. Each PRU | ||
| core has a dedicated Instruction RAM, Control and Debug register sets, and | ||
| use the Data RAMs present within the PRU-ICSS for code execution. | ||
| The K3 SoCs containing ICSSG v1.0 (eg: AM65x SR1.0) also have two Auxiliary | ||
| PRU cores called RTUs with slightly different IP integration. The K3 SoCs | ||
| containing the revised ICSSG v1.1 (eg: J721E, AM65x SR2.0) have an extra two | ||
| auxiliary Transmit PRU cores called Tx_PRUs that augment the PRUs. Each RTU | ||
| or Tx_PRU core can also be used independently like a PRU, or alongside a | ||
| corresponding PRU core to provide/implement auxiliary functionality/support. | ||
| Each PRU, RTU or Tx_PRU core node should be defined as a child node of the | ||
| corresponding PRU-ICSS node. Each node can optionally be rendered inactive by | ||
| using the standard DT string property, "status". | ||
| Please see the overall PRU-ICSS bindings document for additional details | ||
| including a complete example, | ||
