Qualcomm SM8650 audio, compute and modem remoteproc are added. Qualcomm X1 Elite audio and compute remoteprocs are added, after support for shutting down the bootloader-loaded firmware loaded into the audio DSP.. A dozen drivers in the subsystem are transitioned to use devres helpers for remoteproc and memory allocations. It makes it possible to acquire in-kernel handle to individual remoteproc instances in a cluster. The release of DMA memory for remoteproc virtio is corrected to ensure that restarting due to a watchdog bite doesn't attempt to allocate the memory again without first freeing it. Last, but not least, a couple of DeviceTree binding cleanups. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmX3oxcVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FargP/1kVpsEZbzaqc3v0OJBShG45gpQR O9wIfP0T9KrZGDSayAGX7/c80cvLl3y/ukkwY6ehGLrV2iOQ2+7fhV9vLDe09a95 mMkcE3d3WFrlDPGPjquTRlCFjkBcK/WloQWBQZZ+ZtCxjfUjwKxtPutB7XPCQC4r Ky3qUUhkxhXSD2R8Vr8PSDtdMxwj991A7Ejo+wRYEzv40atiJ0M3v9/hjNeIinVz zui6EOB0p9s4geDfD7uAbbDfwi7CxvlprC3AcAYz4KWV1q5Dh8NhYI0KqcF03G8q pCpJHuHYBBiarAvflKe99KLSiVz7+GOtcz2a4d4YBSbePliW+HafPXugUqBG/RtC TzH1H4NuS+07JyYlklz/lC3Do284LimSrGlGMR+uypY8sLWRVSHBazTJypGHOUZd ei/E3Nf7hbEkBh31o4lTMVrVT/zTXKe2gdzAM7dgom6euav8OiUEgpVdc2ye3oHf 0Xmeb8UXAVTCZEfHqgKr3QO3v3wAbarbJ/UZiPHeN/5kFUxbTxpRAmpTeI4ViKk3 KDbqibnx6YI8UHkAPgQalf1x37z2f1b/DEfi3nulzwLsZ0UgvoZy5Zim7RSS/R5K JFqMNKPj0m2J6LF+2YTjZL6Af989mWmLOLPTM6szpWvEil/ndRTqWaAKOilWeGJu wqVp6JrREfPhHsWY =na/C -----END PGP SIGNATURE----- Merge tag 'rproc-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "Qualcomm SM8650 audio, compute and modem remoteproc are added.
