Merge tag 'icc-5.10-rc1' of https://git.linaro.org/people/georgi.djakov/linux into char-misc-next
Georgi writes: interconnect changes for 5.10 Here are the interconnect changes for the 5.10-rc1 merge window consisting of core changes, new drivers and cleanups. Core changes: - New bulk API helpers for managing multiple interconnect paths. - New xlate_extended() interface for parsing additional data from DT. - Support for sync_state(). Driver changes: - New drivers for SM8150 and SM8250 platforms. - New drivers for the Qualcomm OSM and EPSS hardware blocks. - Per-BCM scaling factor support. - Misc cleanups.
