Subject: [PATCH v2 0/4] qcom-cpufreq-hw LMH irq/hotplug interractions
Date:   Mon,  4 Jul 2022 13:27:35 +0200
Message-Id: <20220704112739.3020516-1-pierre.gondois@arm.com>

Precedence: bulk

v2:
- Rebased on v5.19-rc5
- Changed irq checks from '< 0' to '<= 0' to be aligned

The patch-set was tested on a rb5 with an old firmware version:
UEFI Ver    : 5.0.210817.BOOT.XF.3.2-00354-SM8250-1
Build Info  : 64b Aug 17 2021 23:35:39

commit ffd6cc92ab9c ("arm64: dts: qcom: sm8250: add description of dcvsh
interrupts")
enables DCVS (Dynamic Clock and Voltage Scaling) for sm8250 chips
(so rb5 included). As no LMH (Limits Management Hardware) interrupts
were seen, the firmware used for testing should not be able support
them.

This patch-set should still contain relevant modifications regarding
LMH interrupts and CPU hotplug. Still, it would be good to test
it on a platform which actually uses LMH interrupts.

Pierre Gondois (4):
  cpufreq: qcom-hw: Reset cancel_throttle when policy is re-enabled
  cpufreq: qcom-hw: Disable LMH irq when disabling policy
  cpufreq: qcom-hw: Remove deprecated irq_set_affinity_hint() call
  cpufreq: Change order of online() CB and policy->cpus modification
