Merge tag 'char-misc-5.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc into master
Pull char/misc driver fixes from Greg KH: "Here are a few small driver fixes for 5.8-rc7 They include: - habanalabs fixes - tiny fpga driver fixes - /dev/mem fixup from previous changes - interconnect driver fixes - binder fix All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-5.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: interconnect: msm8916: Fix buswidth of pcnoc_s nodes interconnect: Do not skip aggregation for disabled paths /dev/mem: Add missing memory barriers for devmem_inode binder: Don't use mmput() from shrinker function. habanalabs: prevent possible out-of-bounds array access fpga: dfl: fix bug in port reset handshake fpga: dfl: pci: reduce the scope of variable 'ret' habanalabs: set 4s timeout for message to device CPU habanalabs: set clock gating per engine habanalabs: block WREG_BULK packet on PDMA

gating mechanism in Gaudi. Due to how Gaudi is built, the
clock gating needs to be disabled in order to access the
registers of the TPC and MME engines. This is sometimes needed
- during debug by the user and hence the user needs this option
+ during debug by the user and hence the user needs this option.
+ The user can supply a bitmask value, each bit represents
+ a different engine to disable/enable its clock gating feature.
+ The bitmask is composed of 20 bits:
+ 0 - 7 : DMA channels
+ 8 - 11 : MME engines
+ 12 - 19 : TPC engines
+ The bit's location of a specific engine can be determined
+ using (1 << GAUDI_ENGINE_ID_*). GAUDI_ENGINE_ID_* values
+ are defined in uapi habanalabs.h file in enum gaudi_engine_id
