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 ...

mei: expose device state in sysfs

2019-04-25T17:33:34+00:00

Expose mei device state to user-space through sysfs. This gives indication to applications that driver is in transition, usefully mostly to detect link reset state. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: hdcp: use own Kconfig file

2019-04-25T17:33:34+00:00

The mei/hdcp module have its own Makefile so naturally it should have associated Kconfig in the same directory. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

drivers: Remove explicit invocations of mmiowb()

2019-04-08T11:01:02+00:00

mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

mei: bus: move hw module get/put to probe/release

2019-02-26T10:53:56+00:00

Fix unbalanced module reference counting during internal reset, which prevents the drivers unloading. Tracking mei_me/txe modules on mei client bus via mei_cldev_enable/disable is error prone due to possible internal reset flow, where clients are disconnected underneath. Moving reference counting to probe and release of mei bus client driver solves this issue in simplest way, as each client provides only a single connection to a client bus driver.
