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"

+Qualcomm Always-On Subsystem side channel binding
+
+This binding describes the hardware component responsible for side channel
+requests to the always-on subsystem (AOSS), used for certain power management
+requests that is not handled by the standard RPMh interface. Each client in the
+SoC has it's own block of message RAM and IRQ for communication with the AOSS.
+The protocol used to communicate in the message RAM is known as Qualcomm
+Messaging Protocol (QMP)
+
+The AOSS side channel exposes control over a set of resources, used to control
+a set of debug related clocks and to affect the low power state of resources
+related to the secondary subsystems. These resources are exposed as a set of
+power-domains.
+

+- reg:
+	Usage: required

+= SUBNODES
+The AOSS side channel also provides the controls for three cooling devices,
