2025-12-15dt-bindings: display: rockchip: dw-hdmi: Add compatible for RK3368 HDMIHeiko Stuebner1-0/+1
Define a new compatible for RK3368 HDMI. The RK3368 HDMI also uses a PHY internal to the controller, so works similar to other controllers, with the exception that the RK3368 only has one VOP, so there is no source selection needed.

2025-12-15fs: Remove internal old mount API codeEric Sandeen4-70/+5
Now that the last in-tree filesystem has been converted to the new mount API, remove all legacy mount API code designed to handle un-converted filesystems, and remove associated documentation as well. (The code to handle the legacy mount(2) syscall from userspace is still in place, of course.) Tested with an allmodconfig build on x86_64, and a sanity check of an old mount(2) syscall mount.

2025-12-15PM: sleep: Do not flag runtime PM workqueue as freezableRafael J. Wysocki1-4/+3
Till now, the runtime PM workqueue has been flagged as freezable, so it does not process work items during system-wide PM transitions like system suspend and resume. The original reason to do that was to reduce the likelihood of runtime PM getting in the way of system-wide PM processing, but now it is mostly an optimization because (1) runtime suspend of devices is prevented by bumping up their runtime PM usage counters in device_prepare() and (2) device drivers are expected to disable runtime PM for the devices handled by them before they embark on system-wide PM activities that may change the state of the hardware or otherwise interfere with runtime PM. However, it prevents asynchronous runtime resume of devices from working during system-wide PM transitions, which is confusing because synchronous runtime resume is not prevented at the same time, and it also sometimes turns out to be problematic. For example, it has been reported that blk_queue_enter() may deadlock during a system suspend transition because of the pm_request_resume() usage in it [1]. It may also deadlock during a system resume transition in a similar way. That happens because the asynchronous runtime resume of the given device is not processed due to the freezing of the runtime PM workqueue. While it may be better to address this particular issue in the block layer, the very presence of it means that similar problems may be expected to occur elsewhere. For this reason, remove the WQ_FREEZABLE flag from the runtime PM workqueue and make device_suspend_late() use the generic variant of pm_runtime_disable() that will carry out runtime PM of the device synchronously if there is pending resume work for it. Also update the comment before the pm_runtime_disable() call in device_suspend_late(), to document the fact that the runtime PM should not be expected to work for the device until the end of device_resume_early(), and update the related documentation. This change may, even though it is not expected to, uncover some latent issues related to queuing up asynchronous runtime resume work items during system suspend or hibernation. However, they should be limited to the interference between runtime resume and system-wide PM callbacks in the cases when device drivers start to handle system-wide PM before disabling runtime PM as described above.

Add a new libata.force parameter called max_sec. The parameter can take an arbitrary value using the format: libata.force=max_sec=<number of 512B sectors> e.g. libata.force=max_sec=8191 or libata.force=max_sec=2048 This will allow the user to set an arbitrary maximum command size (dev->max_sectors) using libata.force. We cannot remove the existing libata.force parameters "max_sec_128" and "max_sec_1024", as these are a part of the exising user facing API.
