2025-02-13drm/i2c: tda998x: drop support for platform_dataDmitry Baryshkov
After the commit 0fb2970b4b6b ("drm/armada: remove non-component support") there are no remaining users of the struct tda998x_encoder_params. Drop the header and corresponding API from the TDA998x driver.

2025-02-12drm/v3d: Add clock handlingStefan Wahren
Since the initial commit 57692c94dcbe ("drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+") the struct v3d_dev reserved a pointer for an optional V3D clock. But there wasn't any code, which fetched it. So add the missing clock handling before accessing any V3D registers.

2025-02-12drm/sched: Use struct for drm_sched_init() paramsPhilipp Stanner
drm_sched_init() has a great many parameters and upcoming new functionality for the scheduler might add even more. Generally, the great number of parameters reduces readability and has already caused one missnaming, addressed in: commit 6f1cacf4eba7 ("drm/nouveau: Improve variable name in nouveau_sched_init()"). Introduce a new struct for the scheduler init parameters and port all users.

2025-02-12drm: zynqmp_dp: Use scope-based mutex helpersSean Anderson
Convert most mutex_(un)lock calls to use (scoped_)guard instead. This generally reduces line count and prevents bugs like forgetting to unlock the mutex. I've left traditional calls in a few places where scoped helpers would be more verbose. This mostly happens where debugfs_file_put needs to be called regardless. I looked into defining a CLASS for debugfs_file, but it seems like more effort than it's worth since debugfs_file_get can fail.

2025-02-11drm/edp-panel: Add panel used by T14s Gen6 SnapdragonSebastian Reichel
The Lenovo Thinkpad T14s Gen6 Snapdragon is currently sold with three different panel versions: OLED, Low Power IPS or IPS with Touchscreen. My Low Power IPS version had this panel and the kernel complained about not knowing any details.

2025-02-09PM: sleep: core: Restrict power.set_active propagationRafael J. Wysocki
Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of parents and children") exposed an issue related to simple_pm_bus_pm_ops that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as bus type PM callbacks for the noirq phases of system-wide suspend and resume. The problem is that pm_runtime_force_suspend() does not distinguish runtime-suspended devices from devices for which runtime PM has never been enabled, so if it sees a device with runtime PM status set to RPM_ACTIVE, it will assume that runtime PM is enabled for that device and so it will attempt to suspend it with the help of its runtime PM callbacks which may not be ready for that. As it turns out, this causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer dereference. Another problem related to the above commit and simple_pm_bus_pm_ops is that setting runtime PM status of a device handled by the latter to RPM_ACTIVE will actually prevent it from being resumed because pm_runtime_force_resume() only resumes devices with runtime PM status set to RPM_SUSPENDED. To mitigate these issues, do not allow power.set_active to propagate beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that will need to be resumed, which should be a sufficient stop-gap for the time being, but they will need to be properly addressed in the future because in general during system-wide resume it is necessary to resume all devices in a dependency chain in which at least one device is going to be resumed.
