The minimum frequency requirement is provided in the devide-tree node. Setting a minimum frequency for the CPUs is needed to ensure a quick handling of the interrupts between two sensor frames and avoid dropping half of them. version 7: - rebase on v5.8-rc3 - add reviewed and ack-by - fix test condition version 6: - come back to version 4 and follow Valentin's suggestions about notifier version 5: - add a mutex to protect dcmi_irq_notifier_notify() - register notifier a probe time version 4: - simplify irq affinity handling by using only dcmi_irq_notifier_notify() version 3: - add a cpumask field to track boosted CPUs - add irq_affinity_notify callback - protect cpumask field with a mutex Benjamin Gaignard (3): dt-bindings: media: stm32-dcmi: Add DCMI min frequency property media: stm32-dcmi: Set minimum cpufreq requirement ARM: dts: stm32: Set DCMI frequency requirement for stm32mp15x .../devicetree/bindings/media/st,stm32-dcmi.yaml | 8 ++ arch/arm/boot/dts/stm32mp151.dtsi | 1 + drivers/media/platform/stm32/stm32-dcmi.c | 138 +++++++++++++++++++-- 3 files changed, 139 insertions(+), 8 deletions(-) -- 2.15.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
