Merge tag 'char-misc-5.2-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc update part 2 from Greg KH: "Here is the "real" big set of char/misc driver patches for 5.2-rc1 Loads of different driver subsystem stuff in here, all over the places: - thunderbolt driver updates - habanalabs driver updates - nvmem driver updates - extcon driver updates - intel_th driver updates - mei driver updates - coresight driver updates - soundwire driver cleanups and updates - fastrpc driver updates - other minor driver updates - chardev minor fixups Feels like this tree is getting to be a dumping ground of "small driver subsystems" these days. Which is fine with me, if it makes things easier for those subsystem maintainers. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-5.2-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (255 commits) intel_th: msu: Add current window tracking intel_th: msu: Add a sysfs attribute to trigger window switch intel_th: msu: Correct the block wrap detection intel_th: Add switch triggering support intel_th: gth: Factor out trace start/stop intel_th: msu: Factor out pipeline draining intel_th: msu: Switch over to scatterlist intel_th: msu: Replace open-coded list_{first,last,next}_entry variants intel_th: Only report useful IRQs to subdevices intel_th: msu: Start handling IRQs intel_th: pci: Use MSI interrupt signalling intel_th: Communicate IRQ via resource intel_th: Add "rtit" source device intel_th: Skip subdevices if their MMIO is missing intel_th: Rework resource passing between glue layers and core intel_th: SPDX-ify the documentation intel_th: msu: Fix single mode with IOMMU coresight: funnel: Support static funnel dt-bindings: arm: coresight: Unify funnel DT binding coresight: replicator: Add new device id for static replicator ...
