Pull devicetree updates from Rob Herring:
"DT core:
- Fix node refcounting in of_find_last_cache_level()
- Constify device_node in of_device_compatible_match()
- Fix 'dma-ranges' handling in bus controller nodes
- Fix handling of initrd start > end
- Improve error reporting in of_irq_init()
- Taint kernel on DT unittest running
- Use strscpy instead of strlcpy
- Add a build target, dt_compatible_check, to check for compatible
strings used in kernel sources against compatible strings in DT
schemas.
- Handle DT_SCHEMA_FILES changes when rebuilding
DT bindings:
- LED bindings for MT6370 PMIC
- Convert Mediatek mtk-gce mailbox, MIPS CPU interrupt controller,
mt7621 I2C, virtio,pci-iommu, nxp,tda998x, QCom fastrpc, qcom,pdc,
and arm,versatile-sysreg to DT schema format
- Add nvmem cells to u-boot,env schema
- Add more LED_COLOR_ID definitions
- Require 'opp-table' uses to be a node
- Various schema fixes to match QEMU 'virt' DT usage
- Tree wide dropping of redundant 'Device Tree Binding' in schema
titles
- More (unevaluated|additional)Properties fixes in schema child nodes
- Drop various redundant minItems equal to maxItems"

Bandwidth Monitor measures current throughput on buses between various NoC
|
|
fabrics and provides information when it crosses configured thresholds.
|
|
|
|
Certain SoCs might have more than one Bandwidth Monitors, for example on SDM845::
|
|
- Measuring the bandwidth between CPUs and Last Level Cache Controller -
|
|
called just BWMON,
|
|
- Measuring the bandwidth between Last Level Cache Controller and memory
|
|
(DDR) - called LLCC BWMON.
