Linus Torvalds 2c54e18406 remoteproc updates for v5.18
In the remoteproc core, it's now possible to mark the sysfs attributes
 read only on a per-instance basis, which is then used by the TI wkup M3
 driver. The rproc_shutdown() interface propagates errors to the caller
 and an array underflow is fixed in the debugfs interface. The
 rproc_da_to_va() API is moved to the public API to allow e.g. child
 rpmsg devices to acquire pointers to memory shared with the remote
 processor.
 
 The TI K3 R5F and DSP drivers gains support for attaching to instances
 already started by the bootloader, aka IPC-only mode.
 
 The Mediatek remoteproc driver gains support for the MT8186 SCP. The
 driver's probe function is reordered and moved to use the devres version
 of rproc_alloc() to save a few gotos. The driver's probe function is
 also transitioned to use dev_err_probe() to provide better debug
 support.
 
 Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is introduced.
 The Hexagon based remoteproc drivers gains support for voting for
 interconnect bandwidth during launch of the remote processor. The modem
 subsystem (MSS) driver gains support for probing the BAM-DMUX
 driver, which provides the network interface towards the modem on a set
 of older Qualcomm platforms.
 In addition a number a bug fixes are introduces in the Qualcomm drivers.
 
 Lastly Qualcomm ADSP DeviceTree binding is converted to YAML format, to
 allow validation of DeviceTree source files.
