[PATCH v2 1/2] platform/loongarch: laptop: Get brightness setting from EC on probe

by Yao Zi

Previously during probe, 1 is unconditionally taken as current brightness value and set to props.brightness, which will be considered as the brightness before suspend and restored to EC on resume. Since a brightness value of 1 almost never matches EC's state on coldboot (my laptop's EC defaults to 80), this causes surprising changes of screen brightness on the first time of resume after coldboot. Let's get brightness from EC and take it as the current brightness on probe of the laptop driver to avoid the surprising behavior. Tested on TongFang L860-T2 3A5000 laptop.

[PATCH v1 1/2] usb: xhci: Skip xhci_reset in xhci_resume if xhci is being removed

by Roy Luo

xhci_reset() currently returns -ENODEV if XHCI_STATE_REMOVING is set, without completing the xhci handshake, unless the reset completes exceptionally quickly. This behavior causes a regression on Synopsys DWC3 USB controllers with dual-role capabilities. Specifically, when a DWC3 controller exits host mode and removes xhci while a reset is still in progress, and then attempts to configure its hardware for device mode, the ongoing, incomplete reset leads to critical register access issues. All register reads return zero, not just within the xHCI register space (which might be expected during a reset), but across the entire DWC3 IP block. This patch addresses the issue by preventing xhci_reset() from being called in xhci_resume() and bailing out early in the reinit flow when XHCI_STATE_REMOVING is set.

Backports for 6.1 and older due to clang -Qunused-arguments change

by Nathan Chancellor

Hi Greg and Sasha, Please find attached backports for commit feb843a469fb ("kbuild: add $(CLANG_FLAGS) to KBUILD_CPPFLAGS") and its dependent changes, commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper flags and language target") and its dependent changes, and commit 7db038d9790e ("drm/amd/display: Do not add '-mhard-float' to dml_ccflags for clang") for 6.1 and earlier. The second listed change is already in 6.1 so that series is a little shorter. These changes are needed there due to an upstream LLVM change [1] that changes the behavior of -Qunused-arguments with unknown target options, which is only used in 6.1 and older since I removed it in commit 8d9acfce3332 ("kbuild: Stop using '-Qunused-arguments' with clang") in 6.3. Please let me know if there are any issues, I will try to pay attention for any issues that crop up in the stable review period from these changes but please ping me if you remember. Cheers, Nathan [1]: https://github.com/llvm/llvm-project/commit/a4b2f4a72aa9b4655ecc723838830e0…

[PATCH v2 1/4] arm64: dts: imx8mp-venice-gw71xx: fix TPM SPI frequency

by Tim Harvey

The IMX8MPDS Table 37 [1] shows that the max SPI master read frequency depends on the pins the interface is muxed behind with ECSPI2 muxed behind ECSPI2 supporting up to 25MHz.
