Pull arm64 perf updates from Will Deacon:
"The main addition here is support for Broadcom's Vulcan core using the
architected ID registers for discovering supported events.
- Support for the PMU in Broadcom's Vulcan CPU
- Dynamic event detection using the PMCEIDn_EL0 ID registers"
* tag 'arm64-perf' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: perf: don't expose CHAIN event in sysfs
arm64/perf: Add Broadcom Vulcan PMU support
arm64/perf: Filter common events based on PMCEIDn_EL0
arm64/perf: Access pmu register using <read/write>_sys_reg
arm64/perf: Define complete ARMv8 recommended implementation defined events
arm64/perf: Changed events naming as per the ARM ARM
arm64: dts: Add Broadcom Vulcan PMU in dts
Documentation: arm64: pmu: Add Broadcom Vulcan PMU binding
The PCI memory windows available in vulcan.dtsi are limited to 128MB
for 32-bit BARs, and 4GB for 64-bit BARs. Given the memory mapped IO
space available in arm64, these windows can be increased substantially
to support more use cases.
The change increases the 32-bit window to 256MB and the 64-bit window
to 128 GB. The firmware on vulcan boards will use these ranges as well.
PCI IO windows are not supported on Vulcan, so remove them instead of
keeping an unused value.

Add a configuration option and a device tree for Broadcom's Vulcan
ARM64 processor. vulcan.dtsi has the on-chip blocks like the PCIe
controller, GICv3 with ITS, PMU, system timer and the pl011 UART.
vulcan-eval.dts has definitions for a basic evaluation board.
Vulcan's processor cores support the ARMv8.1 instruction set and
will use "brcm,vulcan" as the compatible property. The firmware
has PSCI 0.2 support for cpu wakeup.
