Linus Torvalds 5d5d353bed remoteproc updates for v5.20
This introduces support for the remoteproc on Mediatek MT8188, and
 enables caches for MT8186 SCP. It adds support for PRU cores found on
 the TI K3 AM62x SoCs.
 
 It moves the recovery work after a firmware crash to an unbound
 workqueue, to allow recovery to happen in parallel.
 
 A new DMA API is introduced to release dma_mem for a device.
 
 It adds support a panic handler for the Qualcomm modem remoteproc, with
 the goal of having caches flushed in memory dumps for post-mortem
 debugging and it introduces a mechanism to wait for the modem firmware
 on SM8450 to decrypt part of its memory for post-mortem debugging.
 
 Qualcomm sysmon is restricted to only inform remote processors about
 peers that are actually running, to avoid a race where Linux tries to
 notify a recovering remote processor about its peers new state. A
 mechanism for waiting for the sysmon connection to be established is also
 introduced, to avoid out-of-sync updates for rapidly restarting remote
 processors.
 
 A number of Devicetree binding cleanups and conversions to YAML are
 introduced, to facilitate Devicetree validation. Lastly it introduces a
 number of smaller fixes and cleanups in the core and a few different
 drivers.
