Date: Tue, 29 Sep 2026 06:32:15 +0000 [thread overview]
Message-ID: <20260929063215.AEB4D1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260929034510.2023173-15-praan@google.com>
> Enable PM runtime for SMMUs having a power-domain during smmu probe.
> Add a devlink between the clients and SMMU device. The absence of a
> power domain effectively disables runtime power management.
>
> Additionally, handle runtime PM teardown in arm_smmu_disable_action()
> and skip MMIO accesses during teardown and shutdown if the SMMU is
> already runtime suspended, as translation is already disabled and the
> hardware is in a low-power state.
