2025-05-05pinctrl: renesas: rzg2l: Add support for RZ/V2N SoCLad Prabhakar
Add pinctrl support for the Renesas RZ/V2N SoC by reusing the existing RZ/V2H(P) pin configuration data. The PFC block is nearly identical, with the only difference being the absence of `PCIE1_RSTOUTB` on RZ/V2N. To handle this, the rzv2h_dedicated_pins array is refactored into a common and pcie1 subset. This enables reuse of the common portion across both SoCs, while excluding PCIE1_RSTOUTB for RZ/V2N. This change allows the pinctrl-rzg2l driver to support RZ/V2N without duplicating large parts of the RZ/V2H configuration.

The "media: atomisp: Add support for sensors with a separate ISP v4l2_subdev" combined with some pending drivers/media/i2c/mt9m114.c changes makes the atomisp work nicely with the standard V4L2 mt9m114.c driver, avoiding the need for the atomisp specific atomisp-mt9m114 driver. The normal driver actually works better since the atomisp-mt9m114 driver does not have working exposure control, leading to a much too dark image.

Some sensors have an ISP inside the sensor which the sensor driver models as a separate v4l2-subdev, like the mt9m114 sensor-driver does. Since the atomisp driver emulates a standard /dev/video# v4l2-device without requiring the application to be aware of media-controller centric /dev/video# devices this requires some special handling in the driver.

2025-05-05media: atomisp: Avoid deadlock with sensor subdevs with state_lock setHans de Goede
When a (sensor) v4l2_subdev has its state_lock member set to non NULL, then all v4l2_subdev_state-s for the sensor share the same lock. atomisp_init_sensor() calls v4l2_subdev_lock_and_get_active_state() and then later on also tries to lock a separate v4l2_subdev_state used for try calls (rather then changing the active state), while still holding the active state lock. Since this try v4l2_subdev_state shares a lock with the active state this results in a deadlock. Skip locking try_sd_state when sensor->state_lock is set to avoid this.

atomisp_try_fmt() is limiting the width of the requested resolution to 1920 before calling the sensor's try_fmt() method. But it is not limiting the height. In case of the old mode-list based t4ka3 driver which has a mode list of: 736x496 896x736 1936x1096 3280x2464 This results in 3280x2464 being selected when try_fmt is called with a requested resolution of 3280x2464, which is not supported because its width > 1920 . Fix this by also limiting the height when in preview mode.

2025-05-05media: atomisp: gmin: Remove GPIO driven regulator supportHans de Goede
The GMIN code has support for sensors using external regulators enabled by GPIOS, rather then using regulators build into the PMIC. With the exception of the Trekstor ST70408-4 (1) tablet there are no known devices which actually use external regulators for the sensors and the code for this is using deprecated old style GPIO numbers support for which is going away. Remove the GPIO driven regulator support so that the gmin code no longer depends on deprecated GPIO APIs. 1) The GMIN support itself is also deprecated and all sensor drivers still using it are being moved over to use ACPI + runtime-pm and the ST70408-4 shipped with Android as factory OS and thus will have broken ACPI tables for the sensors, so like other Android factory OS tablets it will need a bespoke solution anyways.

But, for the impending enablement of MLO support, tweak the leaf functions to dynamically handle ROC link instance index.

2025-05-04soc: Add VIA/WonderMedia SoC identification driverAlexey Charkov
Add a small SOC bus driver to parse the chip ID and revision made available on VIA/WonderMedia SoCs via their system configuration controller's SCC_ID register. This is intended to select appropriate sets of on-chip device quirks at runtime, as it has been found that even within the same SoC version there can be register-incompatible differences, such as with the SDMMC controller on WM8505 rev. A0-A1 vs. rev. A2. The list of SoC versions is compiled from various vendor source dumps and not all of them have corresponding mainline driver support. Some of them also have been seen with varying on-chip markings while sharing the same hardware chip ID's (as is the case with e.g. WM8850 vs. WM8950). In such cases the selection of names to use here among those seen in various source dumps and chip markings was arbitrary. Suggested by Krzysztof at [1] - thanks a lot!

ACD a.k.a Adaptive Clock Distribution is a feature which helps to reduce the power consumption. In some chipsets, it is also a requirement to support higher GPU frequencies. This patch adds support for GPU ACD by sending necessary data to GMU and AOSS. The feature support for the chipset is detected based on devicetree data.

Really the only purpose of this was to limit the address space size to 4GB to avoid 32b rollover problems in 64b pointer math in older sqe fw. So replace the address_space_size with a quirk limiting the address space to 4GB.

2025-05-04drm/msm: Be more robust when HFI response times outConnor Abbott
If the GMU takes too long to respond to an HFI message, we may return early. If the GMU does eventually respond, and then we send a second message, we will see the response for the first, throw another error, and keep going. But we don't currently wait for the interrupt from the GMU again, so if the second response isn't there immediately we may prematurely return. This can cause a continuous cycle of missed HFI messages, and for reasons I don't quite understand the GMU does not shut down properly when this happens. Fix this by waiting for the GMU interrupt when we see an empty queue. If the GMU never responds then the queue really is empty and we quit. We can't wait for the interrupt when we see a wrong response seqnum because the GMU might have already queued both responses by the time we clear the interrupt the first time so we do need to check the queue before waiting on the interrupt again.

2025-05-04drm/msm/gpu: Fix crash when throttling GPU immediately during bootStephan Gerhold
There is a small chance that the GPU is already hot during boot. In that case, the call to of_devfreq_cooling_register() will immediately try to apply devfreq cooling, as seen in the following crash: Unable to handle kernel paging request at virtual address 0000000000014110 pc : a6xx_gpu_busy+0x1c/0x58 [msm] lr : msm_devfreq_get_dev_status+0xbc/0x140 [msm] Call trace: a6xx_gpu_busy+0x1c/0x58 [msm] (P) devfreq_simple_ondemand_func+0x3c/0x150 devfreq_update_target+0x44/0xd8 qos_max_notifier_call+0x30/0x84 blocking_notifier_call_chain+0x6c/0xa0 pm_qos_update_target+0xd0/0x110 freq_qos_apply+0x3c/0x74 apply_constraint+0x88/0x148 __dev_pm_qos_update_request+0x7c/0xcc dev_pm_qos_update_request+0x38/0x5c devfreq_cooling_set_cur_state+0x98/0xf0 __thermal_cdev_update+0x64/0xb4 thermal_cdev_update+0x4c/0x58 step_wise_manage+0x1f0/0x318 __thermal_zone_device_update+0x278/0x424 __thermal_cooling_device_register+0x2bc/0x308 thermal_of_cooling_device_register+0x10/0x1c of_devfreq_cooling_register_power+0x240/0x2bc of_devfreq_cooling_register+0x14/0x20 msm_devfreq_init+0xc4/0x1a0 [msm] msm_gpu_init+0x304/0x574 [msm] adreno_gpu_init+0x1c4/0x2e0 [msm] a6xx_gpu_init+0x5c8/0x9c8 [msm] adreno_bind+0x2a8/0x33c [msm] ... At this point we haven't initialized the GMU at all yet, so we cannot read the GMU registers inside a6xx_gpu_busy(). A similar issue was fixed before in commit 6694482a70e9 ("drm/msm: Avoid unclocked GMU register access in 6xx gpu_busy"): msm_devfreq_init() does call devfreq_suspend_device(), but unlike msm_devfreq_suspend(), it doesn't set the df->suspended flag accordingly. This means the df->suspended flag does not match the actual devfreq state after initialization and msm_devfreq_get_dev_status() will end up accessing GMU registers, causing the crash. Fix this by setting df->suspended correctly during initialization.

2025-05-04iio: adc: ad7606: fix raw read for 18-bit chipsDavid Lechner
Fix 18-bit raw read for 18-bit chips by applying a mask to the value we receive from the SPI controller. SPI controllers either return 1, 2 or 4 bytes per word depending on the bits_per_word. For 16-bit chips, there was no problem since they raw data fit exactly in the 2 bytes received from the SPI controller. But now that we have 18-bit chips and we are using bits_per_word = 18, we cannot assume that the extra bits in the 32-bit word are always zero. In fact, with the AXI SPI Engine controller, these bits are not always zero which caused the raw values to read 10s of 1000s of volts instead of the correct value. Therefore, we need to mask the value we receive from the SPI controller to ensure that only the 18 bits of real data are used.
