In the 'mdt_loader.h' header, both the prototype and the inline version of the qcom_mdt_load() function uses 'fw_name' as name for the firmware name parameter. Additionally, the other qcom_mdt_* functions are using that as well. For consistency, rename the 'firmware' parameter in the implementation of the qcom_mdt_load() to 'fw_name' and update the function accordingly. No functional changes.

The qcom_mdt_load_no_init() function is just a simple wrapper around of __qcom_mdt_load(). Since commit 0daf35da397b ("soc: qcom: mdt_loader: Remove pas id parameter") both functions are using the same type of parameters and providing the same functionality. Keeping two functions for the same purpose is superfluous, so rename the __qcom_mdt_load() function to qcom_mdt_load_no_init() and remove the wrapper. No functional changes.

2025-11-01soc: qcom: smem: better track SMEM uninitialized stateChristian Marangi
There is currently a problem where, in the specific case of SMEM not initialized by SBL, any SMEM API wrongly returns PROBE_DEFER communicating wrong info to any user of this API. A better way to handle this would be to track the SMEM state and return a different kind of error than PROBE_DEFER. Rework the __smem handle to always init it to the error pointer -EPROBE_DEFER following what is already done by the SMEM API. If we detect that the SBL didn't initialized SMEM, set the __smem handle to the error pointer -ENODEV. Also rework the SMEM API to handle the __smem handle to be an error pointer and return it appropriately. This way user of the API can react and return a proper error or use fallback way for the failing API. While at it, change the return error when SMEM is not initialized by SBL also to -ENODEV to make it consistent with the __smem handle and use dev_err_probe() helper to return the message.

In the commit referenced by the Fixes tag, devm_clk_get_enabled() was introduced to replace devm_clk_get() and clk_prepare_enable(). While the clk_disable_unprepare() call in the error path was correctly removed, the one in the remove function was overlooked, leading to a double disable issue. Remove the redundant clk_disable_unprepare() call from gsbi_remove() to fix this issue. Since all resources are now managed by devres and will be automatically released, the remove function serves no purpose and can be deleted entirely.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC fixes from Arnd Bergmann: "These are mainly devicetree fixes for the rockchip and nxp platforms on arm64, addressing mistakes in the board and soc specific descriptions. In particular the newly added Rock 5T board required multiple bugfixes for PCIe and USB, while on the i.MX platform there are a number of regulator related fixes. 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. Three drivers each have a simple bugfix, stopping incorrect behavior in op-tee firmware, the tee subsystem and the qualcomm mdt_loader. Two trivial MAINTAINERS file changes are needed to make sure that patches reach the correct maintainer, but don't change the actual responsibilities" * tag 'soc-fixes-6.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (27 commits) ARM: dts: microchip: sama7d65: Force SDMMC Legacy mode ARM: at91: select ARCH_MICROCHIP arm64: dts: rockchip: fix second M.2 slot on ROCK 5T arm64: dts: rockchip: fix USB on RADXA ROCK 5T MAINTAINERS: exclude defconfig from ARM64 PORT arm64: dts: axiado: Add missing UART aliases MAINTAINERS: Update Nobuhiro Iwamatsu's email address arm64: dts: rockchip: Add vcc-supply to SPI flash on Pinephone Pro arm64: dts: rockchip: fix es8388 address on rk3588s-roc-pc arm64: dts: rockchip: Fix Bluetooth interrupts flag on Neardi LBA3368 arm64: dts: rockchip: correct network description on Sige5 arm64: dts: rockchip: Minor whitespace cleanup ARM: dts: rockchip: Minor whitespace cleanup arm64: dts: rockchip: Add supplies for eMMC on rk3588-orangepi-5 arm64: dts: rockchip: Fix the headphone detection on the orangepi 5 plus arm64: dts: imx95: Fix JPEG encoder node assigned clock arm64: dts: imx95-19x19-evk: correct the phy setting for flexcan1/2 arm64: dts: imx8mp: Fix missing microSD slot vqmmc on Data Modul i.MX8M Plus eDM SBC arm64: dts: imx8mp: Fix missing microSD slot vqmmc on DH electronics i.MX8M Plus DHCOM arm64: dts: imx8mp-tqma8mpql: remove virtual 3.3V regulator ...

2025-08-27soc: qcom: rpmh-rsc: Unconditionally clear _TRIGGER bit for TCSSneh Mankad
Unconditionally clear the TCS_AMC_MODE_TRIGGER bit when a transaction completes. Previously this bit was only cleared when a wake TCS was borrowed as an AMC TCS but not for dedicated AMC TCS. Leaving this bit set for AMC TCS and entering deeper low power modes can generate a false completion IRQ. Prevent this scenario by always clearing the TCS_AMC_MODE_TRIGGER bit upon receiving a completion IRQ.

2025-08-18soc: qcom: icc-bwmon: Fix handling dev_pm_opp_find_bw_*() errorsKrzysztof Kozlowski
The ISR calls dev_pm_opp_find_bw_ceil(), which can return EINVAL, ERANGE or ENODEV, and if that one fails with ERANGE, then it tries again with floor dev_pm_opp_find_bw_floor(). In theory, following error paths are possible: 1. First dev_pm_opp_find_bw_ceil() failed with an error different than ERANGE, 2. Any error from second dev_pm_opp_find_bw_floor(). However in practice this would mean that there are no suitable OPPs at all, which is already being checked in the drivers probe() function. This is impossible condition. Relying however in the interrupt handler bwmon_intr_thread() on preconditions checked in probe() is not easy to follow from code readability and is very difficult to handle in static analysis, thus let's make the code just obvious to silence warning reported by Smatch: icc-bwmon.c:693 bwmon_intr_thread() error: 'target_opp' dereferencing possible ERR_PTR() Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Closes: https://lore.kernel.org/r/aJTNEQsRFjrFknG9@stanley.mountain/ Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20250818123851.111326-2-krzysztof.kozlowski@linaro.org Signed-off-by: Bjorn Andersson <andersson@kernel.org>
