Pull asm-generic updates from Arnd Bergmann:
 "There are three independent sets of changes:

   - Sai Prakash Ranjan adds tracing support to the asm-generic version
     of the MMIO accessors, which is intended to help understand
     problems with device drivers and has been part of Qualcomm's vendor
     kernels for many years

   - A patch from Sebastian Siewior to rework the handling of IRQ stacks
     in softirqs across architectures, which is needed for enabling
     PREEMPT_RT

   - The last patch to remove the CONFIG_VIRT_TO_BUS option and some of
     the code behind that, after the last users of this old interface
     made it in through the netdev, scsi, media and staging trees"

Pull ARM SoC drivers from Arnd Bergmann:
 "The SoC driver updates contain changes to improve support for
  additional SoC variants, as well as cleanups an minor bugfixes
  in a number of existing drivers.

  Notable updates this time include:

   - Support for Qualcomm MSM8909 (Snapdragon 210) in various drivers

   - Updates for interconnect drivers on Qualcomm Snapdragon

   - A new driver support for NMI interrupts on Fujitsu A64fx

   - A rework of Broadcom BCMBCA Kconfig dependencies

   - Improved support for BCM2711 (Raspberry Pi 4) power management to
     allow the use of the V3D GPU

   - Cleanups to the NXP guts driver

   - Arm SCMI firmware driver updates to add tracing support, and use
     the firmware interfaces for system power control and for power
     capping"

soc: qcom: spm: Add CPU data for MSM8909

2022-07-18T23:05:07+00:00

Given the lack of public documentation for the SPM, the configuration
data is taken without modification from Qualcomm's msm-3.10 release [1].
It is pretty much identical to the one for MSM8916, except that 0x3B is
missing in the sequence for standalone power collapse for some reason.

MSM8909 has the same power domains as MSM8916, so just define another
compatible for the existing definition.

Add the new "qcom,rpm-msm8909" compatible to the driver so the interface
to the Resource Power Manager (RPM) is initialized correctly on MSM8909.

QCOM_RPMPD requires PM_GENERIC_DOMAINS/_OF, which in turns requires
CONFIG_PM. I forgot about the latter in my earlier patch (it's still
in -next as of the time of committing, hence no Fixes: tag). Fix it.

soc: qcom: icc-bwmon: Add bandwidth monitoring driver

2022-07-06T20:57:51+00:00

Bandwidth monitoring (BWMON) sits between various subsytems like CPU,
GPU, Last Level caches and memory subsystem.  The BWMON can be
configured to monitor the data throuhput between memory and other
subsytems.  The throughput is measured within specified sampling window
and is used to vote for corresponding interconnect bandwidth.

Current implementation brings support for BWMON v4, used for example on
SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level
Cache (memnoc).  Usage of this BWMON allows to remove fixed bandwidth
votes from cpufreq (CPU nodes) thus achieve high memory throughput even
with lower CPU frequencies.

The driver was tested on SDM845.

soc/qcom: Make QCOM_RPMPD select PM_GENERIC_DOMAINS/_OF

2022-07-05T16:16:46+00:00

The driver uses generic genpd OF APIs and with a very minimal config
where nothing else selects them, this driver will not probe, as
of_genpd_add_provider_onecell will return -EOPNOTSUPP.

Make sure to select these in Kconfig to prevent that.
