  remoteproc: qcom_q6v5_mss: Create platform device for BAM-DMUX (2022-03-11 20:21:56 -0600)

----------------------------------------------------------------
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.
