2025-08-25drm/nouveau: remove unused increment in gm200_flcn_pio_imem_wrTimur Tabi
The 'tag' parameter is passed by value and is not actually used after being incremented, so remove the increment. It's the function that calls gm200_flcn_pio_imem_wr that is supposed to (and does) increment 'tag'.

2025-08-25ACPI: PM: Add HP EliteBook 855 G7 WWAN modem power resource quirkMaciej S. Szmigiero
This laptop (and possibly similar models too) has power resource called "GP12.PXP_" for its Intel XMM7360 WWAN modem. For this power resource to turn ON power for the modem it needs certain internal flag called "ONEN" to be set: Method (_ON, 0, NotSerialized) // _ON_: Power On { If (^^^LPCB.EC0.ECRG) { If ((ONEN == Zero)) { Return (Zero) } (..) } } This flag only gets set from this power resource _OFF method, while the actual modem power gets turned off during suspend by "GP12.PTS" method called from the global _PTS (Prepare To Sleep) method. In fact, this power resource _OFF method implementation just sets the aforementioned flag: Method (_OFF, 0, NotSerialized) // _OFF: Power Off { OFEN = Zero ONEN = One } Upon hibernation finish, the kernel tries to set this power resource back ON since its _STA method returns 0 and the resource is still considered in use as it is declared as required for D0 for both the modem ACPI device (GP12.PWAN) and its parent PCIe port ACPI device object (GP12). But the _ON method won't do anything since that "ONEN" flag is not set. Overall, this means the modem is dead after hibernation finish until the laptop is rebooted since the modem power has been cut by _PTS and its PCI configuration was lost and not able to be restored. The easiest way to workaround this issue is to call this power resource _OFF method before calling the _ON method to make sure the "ONEN" flag gets properly set. This makes the modem alive once again after hibernation finish - with properly restored PCI configuration space. Since this platform does *not* support S3 the fact that acpi_resume_power_resources() is also called during resume from S3 is not a problem there. Do the DMI based quirk matching and quirk flag initialization just once - in acpi_power_resources_init() function. This way the whole resume path overhead of this change on other systems amounts to simple hp_eb_gp12pxp_quirk flag comparison. Signed-off-by: Maciej S.

2025-08-25ACPI: PM: Add power resource init functionMaciej S. Szmigiero
This way DMI based quirk matching and quirk flag initialization can be done just once - in the newly introduced acpi_power_resources_init() function, which is similar to existing acpi_*_init() functions. Convert the single already existing DMI match-based quirk in this ACPI power resource handler ("leave unused power resources on" quirk) to such one-time initialization in acpi_power_resources_init() function instead of re-running that DMI match each time acpi_turn_off_unused_power_resources() gets called.

2025-08-25rpmsg: char: Export alias for RPMSG ID rpmsg-raw from tableAndrew Davis
Module aliases are used by userspace to identify the correct module to load for a detected hardware. The currently supported RPMSG device IDs for this module include "rpmsg-raw", but the module alias is "rpmsg_chrdev". Use the helper macro MODULE_DEVICE_TABLE(rpmsg) to export the correct supported IDs. And while here, to keep backwards compatibility we also add the other ID "rpmsg_chrdev" so that it is also still exported as an alias. This has the side benefit of adding support for some legacy firmware which still uses the original "rpmsg_chrdev" ID. This was the ID used for this driver before it was upstreamed (as reflected by the module alias).

SoC slider value is set by the user (or the default when user has not modified it). To enhance power efficiency dynamically, the firmware can optionally auto-adjust the slider value based on the current workload. This adjustment is governed by an additional parameter known as the "slider offset". This offset permits the firmware to increase the slider value up to and including "SoC slider + slider offset". Add a module parameter to specify this "slier offset" value. By default, the SoC slider offset is set to 0. This means that SoC is not allowed to switch slider position.

2025-08-25media: mc: Fix MUST_CONNECT handling for pads with no linksLaurent Pinchart
Commit b3decc5ce7d7 ("media: mc: Expand MUST_CONNECT flag to always require an enabled link") expanded the meaning of the MUST_CONNECT flag to require an enabled link in all cases. To do so, the link exploration code was expanded to cover unconnected pads, in order to reject those that have the MUST_CONNECT flag set. The implementation was however incorrect, ignoring unconnected pads instead of ignoring connected pads. Fix it.

Multiple Sony IMX sensor drivers have mixed up logical and line level for XCLR signal.

2025-08-25media: ti: j721e-csi2rx: Support multiple pixels per clockJai Luthra
Add support for negotiating the highest possible pixel mode (from single, dual, quad) with the Cadence CSI2RX bridge. This is required to drain the Cadence stream FIFOs without overflowing when the source is operating at a high link-frequency [1]. Also, update the Kconfig as this introduces a hard build-time dependency on the Cadence CSI2RX driver, even for a COMPILE_TEST.

2025-08-25media: cadence: cdns-csi2rx: Support multiple pixels per clock cycleJai Luthra
The output pixel interface is a parallel bus (32 bits), which supports sending multiple pixels (1, 2 or 4) per clock cycle for smaller pixel widths like RAW8-RAW16. Dual-pixel and Quad-pixel modes can be a requirement if the export rate of the Cadence IP in Single-pixel mode maxes out before the maximum supported DPHY-RX frequency, which is the case with TI's integration of this IP [1]. So, we export a function that lets the downstream hardware block request a higher pixel-per-clock on a particular output pad. We check if we can support the requested pixels per clock given the known maximum for the currently configured format. If not, we set it to the highest feasible value and return this value to the caller.

2025-08-25media: ti: j721e-csi2rx: Fix source subdev link creationJai Luthra
We don't use OF ports and remote-endpoints to connect the CSI2RX bridge and this device in the device tree, thus it is wrong to use v4l2_create_fwnode_links_to_pad() to create the media graph link between the two. It works out on accident, as neither the source nor the sink implement the .get_fwnode_pad() callback, and the framework helper falls back on using the first source and sink pads to create the link between them. Instead, manually create the media link from the first source pad of the bridge to the first sink pad of the J721E CSI2RX.
