[PATCH v3 0/3] phy: qcom: edp: Add missing ref clock to x1e80100

by Abel Vesa

According to documentation, the DP PHY on x1e80100 has another clock called ref. The current X Elite devices supported upstream work fine without this clock, because the boot firmware leaves this clock enabled. But we should not rely on that. Also, when it comes to power management, this clock needs to be also disabled on suspend. So even though this change breaks the ABI, it is needed in order to make we disable this clock on runtime PM, when that is going to be enabled in the driver. So rework the driver to allow different number of clocks, fix the dt-bindings schema and add the clock to the DT node as well. Signed-off-by: Abel Vesa <abel.vesa(a)linaro.org> --- Changes in v3: - Use dev_err_probe() on clocks parsing failure. - Explain why the ABI break is necessary. - Drop the extra 'clk' suffix from the clock name. So ref instead of refclk. - Link to v2: https://lore.kernel.org/r/20250903-phy-qcom-edp-add-missing-refclk-v2-0-d88… Changes in v2: - Fix schema by adding the minItems, as suggested by Krzysztof. - Use devm_clk_bulk_get_all, as suggested by Konrad. - Rephrase the commit messages to reflect the flexible number of clocks. - Link to v1: https://lore.kernel.org/r/20250730-phy-qcom-edp-add-missing-refclk-v1-0-6f7… --- Abel Vesa (3): dt-bindings: phy: qcom-edp: Add missing clock for X Elite phy: qcom: edp: Make the number of clocks flexible arm64: dts: qcom: Add missing TCSR ref clock to the DP PHYs .../devicetree/bindings/phy/qcom,edp-phy.yaml | 28 +++++++++++++++++++++- arch/arm64/boot/dts/qcom/x1e80100.dtsi | 12 ++++++---- drivers/phy/qualcomm/phy-qcom-edp.c | 16 ++++++------- 3 files changed, 43 insertions(+), 13 deletions(-) --- base-commit: 65dd046ef55861190ecde44c6d9fcde54b9fb77d change-id: 20250730-phy-qcom-edp-add-missing-refclk-5ab82828f8e7 Best regards, -- Abel Vesa <abel.vesa(a)linaro.org>

[PATCH AUTOSEL 6.17-6.6] hwmon: (k10temp) Add device ID for Strix Halo

by Sasha Levin

From: Rong Zhang <i(a)rong.moe> [ Upstream commit e5d1e313d7b6272d6dfda983906d99f97ad9062b ] The device ID of Strix Halo Data Fabric Function 3 has been in the tree since commit 0e640f0a47d8 ("x86/amd_nb: Add new PCI IDs for AMD family 0x1a"), but is somehow missing from k10temp_id_table. Add it so that it works out of the box. Tested on Beelink GTR9 Pro Mini PC. Signed-off-by: Rong Zhang <i(a)rong.moe> Reviewed-by: Mario Limonciello <mario.limonciello(a)amd.com> Link: https://lore.kernel.org/r/20250823180443.85512-1-i@rong.moe Signed-off-by: Guenter Roeck <linux(a)roeck-us.net> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: YES – the added ID lets the existing k10temp driver bind to Strix Halo’s DF3 device so users get temperature readings on that platform. - `drivers/hwmon/k10temp.c:560` gains `PCI_DEVICE_ID_AMD_1AH_M70H_DF_F3`, fixing the current omission that prevents the module from attaching to Strix Halo’s Data Fabric function 3 and leaves its sensors unavailable. - The constant already exists in released kernels (`include/linux/pci_ids.h:587`) and is used by the AMD northbridge driver (`arch/x86/kernel/amd_nb.c:98`), so the new table entry simply connects existing infrastructure; no functional code paths change. - Scope is minimal (one ID entry, no new logic), making regression risk negligible; the patch has been verified on shipping hardware (Beelink GTR9 Pro). - For stable backports, this applies cleanly to branches ≥ v6.10 where the PCI ID is defined; older long-term trees would first need commit 0e640f0a47d8 (or an equivalent definition). Natural next step: backport to the relevant stable lines that already carry the Strix Halo PCI ID definition (6.10.y, upcoming 6.11.y, etc.). drivers/hwmon/k10temp.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/hwmon/k10temp.c b/drivers/hwmon/k10temp.c index 2f90a2e9ad496..b98d5ec72c4ff 100644 --- a/drivers/hwmon/k10temp.c +++ b/drivers/hwmon/k10temp.c @@ -565,6 +565,7 @@ static const struct pci_device_id k10temp_id_table[] = { { PCI_VDEVICE(AMD, PCI_DEVICE_ID_AMD_1AH_M20H_DF_F3) }, { PCI_VDEVICE(AMD, PCI_DEVICE_ID_AMD_1AH_M50H_DF_F3) }, { PCI_VDEVICE(AMD, PCI_DEVICE_ID_AMD_1AH_M60H_DF_F3) }, + { PCI_VDEVICE(AMD, PCI_DEVICE_ID_AMD_1AH_M70H_DF_F3) }, { PCI_VDEVICE(AMD, PCI_DEVICE_ID_AMD_1AH_M90H_DF_F3) }, { PCI_VDEVICE(HYGON, PCI_DEVICE_ID_AMD_17H_DF_F3) }, {} -- 2.51.0

[PATCH] drm/amd/display: Fix NULL deref in debugfs odm_combine_segments

[PATCH RESEND] perf: arm_cspmu: fix error handling in arm_cspmu_impl_unregister()

by Ma Ke

driver_find_device() calls get_device() to increment the reference count once a matching device is found. device_release_driver() releases the driver, but it does not decrease the reference count that was incremented by driver_find_device(). At the end of the loop, there is no put_device() to balance the reference count. To avoid reference count leakage, add put_device() to decrease the reference count. Found by code review.

[PATCH] drm/imagination: Optionally depend on POWER_SEQUENCING

by Matt Coster

When the change using pwrseq was added, I nixed the dependency on POWER_SEQUENCING since we didn't want it pulled in on platforms where it's not needed [1]. I hadn't, however, considered the link-time implications of this for configs with POWER_SEQUENCING=m.

[PATCH net v3 2/3] bpf,sockmap: disallow MPTCP sockets from sockmap

by Jiayuan Chen

MPTCP creates subflows for data transmission, and these sockets should not be added to sockmap because MPTCP sets specialized data_ready handlers that would be overridden by sockmap. Additionally, for the parent socket of MPTCP subflows (plain TCP socket), MPTCP sk requires specific protocol handling that conflicts with sockmap's operation(mptcp_prot). This patch adds proper checks to reject MPTCP subflows and their parent sockets from being added to sockmap, while preserving compatibility with reuseport functionality for listening MPTCP sockets. We cannot add this logic to sock_map_sk_state_allowed() because the sockops path doesn't execute this function, and the socket state coming from sockops might be in states like SYN_RECV. So moving sock_map_sk_state_allowed() to sock_{map,hash}_update_common() is not appropriate. Instead, we introduce a new function to handle MPTCP checks.

[PATCH net v3 1/3] net,mptcp: fix proto fallback detection with BPF sockmap

by Jiayuan Chen

When the server has MPTCP enabled but receives a non-MP-capable request from a client, it calls mptcp_fallback_tcp_ops(). Since non-MPTCP connections are allowed to use sockmap, which replaces sk->sk_prot, using sk->sk_prot to determine the IP version in mptcp_fallback_tcp_ops() becomes unreliable. This can lead to assigning incorrect ops to sk->sk_socket->ops. Additionally, when BPF Sockmap modifies the protocol handlers, the original WARN_ON_ONCE(sk->sk_prot != &tcp_prot) check would falsely trigger warnings. Fix this by using the more stable sk_family to distinguish between IPv4 and IPv6 connections, ensuring correct fallback protocol operations are selected even when BPF Sockmap has modified the socket protocol handlers.
