Qualcomm ARM Based Driver Updates for v5.3

* Add ACPI support to Qualcomm GENI SE
* Update Qualcomm Maintainers entry to remove David Brown as maintainer and
  fixup typos and incorrect DT file entry
* Fixup APR domain id usage and making callbacks in non-atomic context
* Add AOSS QMP driver and bindings
* Add power domains for MSM8998 and QCS404 in QCOM RPMPD
* Add corner macros, max state support, and fixups for setting performance state
  for Qcom RPMPD

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:

	Usage: optional

	Value type: <u32>

	Definition: must be 2



= EXAMPLE



The following example represents the AOSS side-channel message RAM and the

mechanism exposing the power-domains, as found in SDM845.



  aoss_qmp: qmp@c300000 {

	  compatible = "qcom,sdm845-aoss-qmp";
