Merge tag 'icc-5.20-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/djakov/icc into char-misc-next
Georgi writes: interconnect changes for 5.20 Here are the interconnect changes for the 5.20-rc1 merge window consisting of two new drivers, misc driver improvements and new device managed API. Core change: - Add device managed bulk API Driver changes: - New driver for NXP i.MX8MP platforms - New driver for Qualcomm SM6350 platforms - Multiple bucket support for Qualcomm RPM-based drivers.

+ able to communicate with the BCM through the Resource State Coordinator (RSC)
+ associated with each execution environment. Provider nodes must point to at

+ can map to multiple RPMh resources.
