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.
+
+- compatible:
+	Usage: required
+	Value type: <string>
+	Definition: must be "qcom,sdm845-aoss-qmp"
+
+- reg:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: the base address and size of the message RAM for this
+		    client's communication with the AOSS
+
+- interrupts:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: should specify the AOSS message IRQ for this client
+
+- mboxes:
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: reference to the mailbox representing the outgoing doorbell
+		    in APCS for this client, as described in mailbox/mailbox.txt
+
+- #clock-cells:
+	Usage: optional
+	Value type: <u32>
+	Definition: must be 0
+		    The single clock represents the QDSS clock.
+
+- #power-domain-cells:
+	Usage: optional
+	Value type: <u32>
+	Definition: must be 1
+		    The provided power-domains are:
+		    CDSP state (0), LPASS state (1), modem state (2), SLPI
+		    state (3), SPSS state (4) and Venus state (5).
+
+= SUBNODES
+The AOSS side channel also provides the controls for three cooling devices,
+these are expressed as subnodes of the QMP node. The name of the node is used
+to identify the resource and must therefor be "cx", "mx" or "ebi".
+
+- #cooling-cells:
