Pull devicetree updates from Rob Herring:
"Bindings:
- Add spi-peripheral-props.yaml references to various SPI device
bindings
- Convert qcom,pm8916-wdt, ds1307, Qualcomm BAM DMA, is31fl319x,
skyworks,aat1290, Rockchip EMAC, gpio-ir-receiver, ahci-ceva, Arm
CCN PMU, rda,8810pl-intc, sil,sii9022, ps2-gpio, and
arm-firmware-suite bindings to DT schema format
- New bindings for Arm virtual platforms display, Qualcomm IMEM
memory region, Samsung S5PV210 ChipID, EM Microelectronic EM3027
RTC, and arm,cortex-a78ae
- Add vendor prefixes for asrock, bytedance, hxt, ingrasys, inventec,
quanta, and densitron
- Add missing MSI and IOMMU properties to host-generic-pci
- Remove bindings for removed EFM32 platform
- Remove old chosen.txt binding (replaced by schema)
- Treewide add missing type information for properties
- Treewide fixing of typos and its vs. it's in bindings. Its all good
now.
- Drop unnecessary quoting in power related schemas
- Several LED binding updates which didn't get picked up
- Move various bindings to proper directories
DT core code:
- Convert unittest GPIO related tests to use fwnode
- Check ima-kexec-buffer against memory bounds
- Print reserved-memory allocation/reservation failures as errors
- Cleanup early_init_dt_reserve_memory_arch()
- Simplify of_overlay_fdt_apply() tail"

title: 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 its 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.

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".
