[PATCH] arm64: dts: rockchip: Remove non-functioning CPU OPPs from RK3576

by Alexey Charkov

Drop the top-frequency OPPs from both the LITTLE and big CPU clusters on RK3576, as neither the opensource TF-A [1] nor the recent (after v1.08) binary BL31 images provided by Rockchip expose those. This fixes the problem [2] when the cpufreq governor tries to jump directly to the highest-frequency OPP, which results in a failed SCMI call leaving the system stuck at the previous OPP before the attempted change.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 3d3c4cd5c62f24bb3cb4511b7a95df707635e00a Mon Sep 17 00:00:00 2001 From: Oleksij Rempel <o.rempel(a)pengutronix.de> Date: Sun, 5 Oct 2025 10:12:03 +0200 Subject: [PATCH] net: usb: asix: hold PM usage ref to avoid PM/MDIO + RTNL deadlock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Prevent USB runtime PM (autosuspend) for AX88772* in bind. usbnet enables runtime PM (autosuspend) by default, so disabling it via the usb_driver flag is ineffective. On AX88772B, autosuspend shows no measurable power saving with current driver (no link partner, admin up/down). The ~0.453 W -> ~0.248 W drop on v6.1 comes from phylib powering the PHY off on admin-down, not from USB autosuspend. The real hazard is that with runtime PM enabled, ndo_open() (under RTNL) may synchronously trigger autoresume (usb_autopm_get_interface()) into asix_resume() while the USB PM lock is held. Resume paths then invoke phylink/phylib and MDIO, which also expect RTNL, leading to possible deadlocks or PM lock vs MDIO wake issues. To avoid this, keep the device runtime-PM active by taking a usage reference in ax88772_bind() and dropping it in unbind(). A non-zero PM usage count blocks runtime suspend regardless of userspace policy (.../power/control - pm_runtime_allow/forbid), making this approach robust against sysfs overrides. Holding a runtime-PM usage ref does not affect system-wide suspend; system sleep/resume callbacks continue to run as before.

[PATCH v4] dmaengine: fsl-edma: Fix clk leak on alloc_chan_resources failure

by Zhen Ni

When fsl_edma_alloc_chan_resources() fails after clk_prepare_enable(), the error paths only free IRQs and destroy the TCD pool, but forget to call clk_disable_unprepare(). This causes the channel clock to remain enabled, leaking power and resources. Fix it by disabling the channel clock in the error unwind path.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 8b5b456222fd604079b5cf2af1f25ad690f54a25 Mon Sep 17 00:00:00 2001 From: Ling Xu <quic_lxu5(a)quicinc.com> Date: Fri, 12 Sep 2025 14:12:33 +0100 Subject: [PATCH] misc: fastrpc: Save actual DMA size in fastrpc_map structure For user passed fd buffer, map is created using DMA calls. The map related information is stored in fastrpc_map structure. The actual DMA size is not stored in the structure. Store the actual size of buffer and check it against the user passed size.
