Pull power management updates from Rafael Wysocki: "As is tradition, cpufreq is the part with the largest number of updates that include core fixes and cleanups as well as updates of several assorted drivers, but there are also quite a few updates related to system sleep, mostly focused on asynchronous suspend and resume of devices and on making the integration of system suspend and resume with runtime PM easier. Runtime PM is also updated to allow some code duplication in drivers to be eliminated going forward and to work more consistently overall in some cases.

drm/dp: Change AUX DPCD probe address from LANE0_1_STATUS to TRAINING_PATTERN_SET

2025-07-15T13:37:57Z

Commit a3ef3c2da675 ("drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS") stopped using the DPCD_REV register for DPCD probing, since this results in link training failures at least when using an Intel Barlow Ridge TBT hub at UHBR link rates (the DP_INTRA_HOP_AUX_REPLY_INDICATION never getting cleared after the failed link training). Since accessing DPCD_REV during link training is prohibited by the DP Standard, LANE0_1_STATUS (0x202) was used instead, as it falls within the Standard's valid register address range (0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) and it fixed the link training on the above TBT hub. However, reading the LANE0_1_STATUS register also has a side-effect at least on a Novatek eDP panel, as reported on the Closes: link below, resulting in screen flickering on that panel. One clear side-effect when doing the 1-byte probe reads from LANE0_1_STATUS during link training before reading out the full 6 byte link status starting at the same address is that the panel will report the link training as completed with voltage swing 0. This is different from the normal, flicker-free scenario when no DPCD probing is done, the panel reporting the link training complete with voltage swing 2. Using the TRAINING_PATTERN_SET register for DPCD probing doesn't have the above side-effect, the panel will link train with voltage swing 2 as expected and it will stay flicker-free. This register is also in the above valid register range and is unlikely to have a side-effect as that of LANE0_1_STATUS: Reading LANE0_1_STATUS is part of the link training CR/EQ sequences and so it may cause a state change in the sink - even if inadvertently as I suspect in the case of the above Novatek panel. As opposed to this, reading TRAINING_PATTERN_SET is not part of the link training sequence (it must be only written once at the beginning of the CR/EQ sequences), so it's unlikely to cause any state change in the sink. As a side-note, this Novatek panel also lacks support for TPS3, while claiming support for HBR2, which violates the DP Standard (the Standard mandating TPS3 for HBR2). Besides the Novatek panel (PSR 1), which this change fixes, I also verified the change on a Samsung (PSR 1) and an Analogix (PSR 2) eDP panel as well as on the Intel Barlow Ridge TBT hub. Note that in the drm-tip tree (targeting the v6.17 kernel version) the i915 and xe drivers keep DPCD probing enabled only for the panel known to require this (HP ZR24w), hence those drivers in drm-tip are not affected by the above problem.

drm/bridge: Pass down connector to drm bridge detect hook

2025-07-14T15:23:18Z

In some application scenarios, we hope to get the corresponding connector when the bridge's detect hook is invoked. In most cases, we can get the connector by drm_atomic_get_connector_for_encoder if the encoder attached to the bridge is enabled, however there will still be some scenarios where the detect hook of the bridge is called but the corresponding encoder has not been enabled yet. For instance, this occurs when the device is hot plug in for the first time. Since the call to bridge's detect is initiated by the connector, passing down the corresponding connector directly will make things simpler.

PM: domains: Add flags to specify power on attach/detach

2025-07-07T18:41:20Z

Calling dev_pm_domain_attach()/dev_pm_domain_detach() in bus driver probe/remove functions can affect system behavior when the drivers attached to the bus use devres-managed resources. Since devres actions may need to access device registers, calling dev_pm_domain_detach() too early, i.e., before these actions complete, can cause failures on some systems. One such example is Renesas RZ/G3S SoC-based platforms. If the device clocks are managed via PM domains, invoking dev_pm_domain_detach() in the bus driver's remove function removes the device's clocks from the PM domain, preventing any subsequent pm_runtime_resume*() calls from enabling those clocks. The second argument of dev_pm_domain_attach() specifies whether the PM domain should be powered on during attachment. Likewise, the second argument of dev_pm_domain_detach() indicates whether the domain should be powered off during detachment. Upcoming changes address the issue described above (initially for the platform bus only) by deferring the call to dev_pm_domain_detach() until after devres_release_all() in device_unbind_cleanup(). The detach_power_off field in struct dev_pm_info stores the detach power off info from the second argument of dev_pm_domain_attach(). Because there are cases where the device's PM domain power-on/off behavior must be conditional (e.g., in i2c_device_probe()), the patch introduces PD_FLAG_ATTACH_POWER_ON and PD_FLAG_DETACH_POWER_OFF flags to be passed to dev_pm_domain_attach(). Finally, dev_pm_domain_attach() and its users are updated to use the newly introduced PD_FLAG_ATTACH_POWER_ON and PD_FLAG_DETACH_POWER_OFF macros. This change is preparatory.
