Enabling the GPU power domain requires that the GPU regulator is enabled. The regulator is enabled at boot time, but automatically gets disabled when there are no users. If the GPU driver is not probed at boot time or rebound while the system is running the system will try to enable the power domain before the regulator is enabled resulting in a failure hanging the whole system. Avoid this by adding an explicit dependency. Reported-by:

Some power domains require extra voltages to be applied. For example trying to enable the GPU power domain on RK3588 fails when the SoC does not have VDD GPU enabled. The same is expected to happen for the NPU, which also has a dedicated supply line. We get the regulator using devm_of_regulator_get(), so a missing dependency in the devicetree is handled gracefully by printing a warning and creating a dummy regulator. This is necessary, since existing DTs do not have the regulator described. They might still work if the regulator is marked as always-on. It is also working if the regulator is enabled at boot time and the GPU driver is probed before the kernel disables unused regulators. The regulator itself is not acquired at driver probe time, since that creates an unsolvable circular dependency. The power domain driver must be probed early, since SoC peripherals need it. Regulators on the other hand depend on SoC peripherals like SPI, I2C or GPIO. MediaTek does not run into this, since they have two power domain drivers. Tested-by:

Add optional support for a voltage supply required to enable a power domain. The binding follows the way it is handled by the Mediatek binding to keep things consistent. This will initially be used by the RK3588 GPU power domain, which fails to be enabled when the GPU regulator is not enabled. It is not limited to that platform, since older generations have similar requirements. They worked around this by marking the regulators as always-on instead of describing the dependency.

Rework the logic, so that the function exits early when the power domain state is already correct to reduce code indentation. No functional change intended. Reviewed-by:

Currently rockchip_do_pmu_set_power_domain prints a warning if there have been errors turning on the power domain, but it does not return any errors and rockchip_pd_power() tries to continue setting up the QOS registers. This usually results in accessing unpowered registers, which triggers an SError and a full system hang. This improves the error handling by forwarding the error to avoid kernel panics. Reviewed-by:

Use the cleanup infrastructure to handle the mutex, which slightly improve code readability for this function. Reviewed-by:

The Rockchip power-domain controller also plans to make use of per-domain regulators similar to the MediaTek power-domain controller. Since existing DTs are missing the regulator information, the kernel should fallback to the automatically created dummy regulator if necessary. Thus the version without the _optional suffix is needed. The Rockchip driver plans to use the managed version, but to be consistent with existing code the unmanaged version is added at the same time.

The bucket in use to upload artifacts to S3, mesa-lava, has an expiration period of a month. If there isn't a kernel uprev in a month, the build job should be retriggered to regenerate them. Meanwhile, some jobs can fail simply because the expired artifacts. A year is a time window that ensures a kernel uprev. Signed-off-by: -

These limits were always defined as 0, but that didn't cause any issue since the driver had hardcoded limits. In commit b4e13e1a ("scsi: ufs: qcom: Add multiple frequency support for MAX_CORE_CLK_1US_CYCLES") the hardcoded limits were removed and the driver started reading them from DT, causing UFS to stop working on MSM8996. Add real UniPro clock limits to fix UFS. Signed-off-by:

Currently this is just set from the special qcom,adreno-smmu iommu. But we are not *yet* using that for a5xx. Meanwhile we still need the HUPCF bit set so iommu faults in CI do not take out the CP and cause a follow- on cascade of fail. On qcom systems, it is safe to set HUPCF everywhere so do that.
