Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC-related driver updates from Olof Johansson:
"Various driver updates for platforms and a couple of the small driver
subsystems we merge through our tree:
- A driver for SCU (system control) on NXP i.MX8QXP
- Qualcomm Always-on Subsystem messaging driver (AOSS QMP)
- Qualcomm PM support for MSM8998
- Support for a newer version of DRAM PHY driver for Broadcom (DPFE)
- Reset controller support for Bitmain BM1880
- TI SCI (System Control Interface) support for CPU control on AM654
processors
- More TI sysc refactoring and rework"
