The only other platforms with devicetree fixes are at91 with a fixup for SD/MMC and a change to enable all the available UARTS on the Axiado reference board. Also on the at91 platform, a Kconfig change addresses a regression that stopped the DMA engine from working in 6.17-rc.

2025-09-03Revert "drm/nouveau: Remove waitque for sched teardown"Philipp Stanner
This reverts: commit bead88002227 ("drm/nouveau: Remove waitque for sched teardown") commit 5f46f5c7af8c ("drm/nouveau: Add new callback for scheduler teardown") from the drm/sched teardown leak fix series: https://lore.kernel.org/dri-devel/20250710125412.128476-2-phasta@kernel.org/ The aforementioned series removed a blocking waitqueue from nouveau_sched_fini(). It was mistakenly assumed that this waitqueue only prevents jobs from leaking, which the series fixed. The waitqueue, however, also guarantees that all VM_BIND related jobs are finished in order, cleaning up mappings in the GPU's MMU. These jobs must be executed sequentially. Without the waitqueue, this is no longer guaranteed, because entity and scheduler teardown can race with each other. Revert all patches related to the waitqueue removal.

2025-09-03spi: spi-fsl-dspi: Target mode improvementsMark Brown
Merge series from James Clark <james.clark@linaro.org>: Improve usability of target mode by reporting FIFO errors and increasing the buffer size when DMA is used. While we're touching DMA stuff also switch to non-coherent memory, although this is unrelated to target mode. With the combination of the commit to increase the DMA buffer size and the commit to use non-coherent memory, the host mode performance figures are as follows on S32G3: # spidev_test --device /dev/spidev1.0 --bpw 8 --size <test_size> --cpha --iter 10000000 --speed 10000000 Coherent (4096 byte transfers): 6534 kbps Non-coherent: 7347 kbps Coherent (16 byte transfers): 447 kbps Non-coherent: 448 kbps Just for comparison running the same test in XSPI mode: 4096 byte transfers: 2143 kbps 16 byte transfers: 637 kbps These tests required hacking S32G3 to use DMA in host mode, although the figures should be representative of target mode too where DMA is used. And the other devices that use DMA in host mode should see similar improvements.

Currently ethtool shows lbrx_packets and lbrx_bytes (Good RX Packets/Octets loopback Count), but doesn't show the TX-side equivalents (lbtx_packets and lbtx_bytes). Add visibility of those missing statistics by adding them to ethtool statistics. In addition, the order of lbrx_bytes and lbrx_packets is not consistent with non-loopback statistics (rx_packets, rx_bytes).

2025-09-03ixgbe: reduce number of reads when getting OROM dataJedrzej Jagielski
Currently, during locating the CIVD section, the ixgbe driver loops over the OROM area and at each iteration reads only OROM-datastruct-size amount of data. This results in many small reads and is inefficient. Optimize this by reading the entire OROM bank into memory once before entering the loop. This significantly reduces the probing time. Without this patch probing time may exceed over 25s, whereas with this patch applied average time of probe is not greater than 5s. without the patch: [14:12:22] ixgbe: Copyright (c) 1999-2016 Intel Corporation.

2025-09-03efistub/x86: Remap inittext read-execute when neededArd Biesheuvel
Recent EFI x86 systems are more strict when it comes to mapping boot images, and require that mappings are either read-write or read-execute. Now that the boot code is being cleaned up and refactored, most of it is being moved into .init.text [where it arguably belongs] but that implies that when booting on such strict EFI firmware, we need to take care to map .init.text (and the .altinstr_aux section that follows it) read-execute as well.

2025-09-03drm: panel-backlight-quirks: Add Steam Deck brightness quirkAntheas Kapenekakis
On the SteamOS kernel, Valve universally makes minimum brightness 0 for all devices. SteamOS is (was?) meant for the Steam Deck, so enabling it universally is reasonable. However, it causes issues in certain devices. Therefore, introduce it just for the Steam Deck here. SteamOS kernel does not have a public mirror, but this replaces commit 806dd74bb225 ("amd/drm: override backlight min value from 12 -> 0") in the latest, as of this writing, SteamOS kernel (6.11.11-valve24).

2025-09-03drm: panel-backlight-quirks: Add brightness mask quirkAntheas Kapenekakis
Certain OLED devices malfunction on specific brightness levels. Specifically, when DP_SOURCE_BACKLIGHT_LEVEL is written to with the first byte being 0x00 and sometimes 0x01, the panel forcibly turns off until the device sleeps again. Below are some examples. This was found by iterating over brighness ranges while printing DP_SOURCE_BACKLIGHT_LEVEL. It was found that the screen would malfunction on specific values, and some of them were collected. Therefore, introduce a quirk where the minor byte of brightness is OR'd with 0x03 to avoid the range of invalid values. This quirk was tested by removing the workarounds and iterating from 0 to 50_000 value ranges with a cadence of 0.2s/it. The range of the panel is 1000...400_000, so the values were slightly interpolated during testing. The custom brightness curve added on 6.15 was disabled. 86016: 10101000000000000 86272: 10101000100000000 87808: 10101011100000000 251648: 111101011100000000 251649: 111101011100000001 86144: 10101000010000000 87809: 10101011100000001 251650: 111101011100000010 Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3803 Tested-by: Philip Müller <philm@manjaro.org> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Antheas Kapenekakis <lkml@antheas.dev> Link: https://lore.kernel.org/r/20250829145541.512671-5-lkml@antheas.dev Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Mario Limonciello (AMD) <superm1@kernel.org>
2025-09-03drm: panel-backlight-quirks: Add secondary DMI matchAntheas Kapenekakis
Using a single DMI match only allows matching per manufacturer. Introduce a second optional match to allow matching make/model. In addition, make DMI optional to allow matching only by EDID.

2025-09-03drm: panel-backlight-quirks: Convert brightness quirk to generic structureAntheas Kapenekakis
Currently, the brightness quirk is limited to minimum brightness only. Refactor it to a structure, so that more quirks can be added in the future. Reserve 0 value for "no quirk", and use u16 to allow minimum brightness up to 255.

2025-09-03drm: panel-backlight-quirks: Make EDID match optionalAntheas Kapenekakis
Currently, having a valid panel_id match is required to use the quirk system. For certain devices, we know that all SKUs need a certain quirk. Therefore, allow not specifying ident by only checking for a match if panel_id is non-zero.

2025-09-03Input: tsc2007 - prevent overflow in pressure calculationJohannes Kirchmair
The touch resistance calculation in the tsc2007 driver is prone to overflow if (z2 - z1) is large and also x is reasonably big. This overflow results in the driver emitting input events when very little touch pressure is applied. In these events the x and y coordinates can be substantially off. Avoid the overflow by using u64 when calculating resistance value.
