2021-11-28fpga: mgr: Use standard dev_release for class driverRuss Weight15-231/+147
The FPGA manager class driver data structure is being treated as a managed resource instead of using the standard dev_release call-back function to release the class data structure. This change removes the managed resource code for the freeing of the class data structure and combines the create() and register() functions into a single register() or register_full() function. The register_full() function accepts an info data structure to provide flexibility in passing optional parameters. The register() function supports the current parameter list for users that don't require the use of optional parameters. The devm_fpga_mgr_register() function is retained, and the devm_fpga_mgr_register_full() function is added.

It's easier to use and understand, and to extend for EHT later, if we use the values here instead of the shifted values.

2021-11-28drm/msm/gpu: Respect PM QoS constraintsRob Clark2-51/+71
Re-work the boost and idle clamping to use PM QoS requests instead, so they get aggreggated with other requests (such as cooling device). This does have the minor side-effect that devfreq sysfs min_freq/ max_freq files now reflect the boost and idle clamping, as they show (despite what they are documented to show) the aggregated min/max freq. Fixing that in devfreq does not look straightforward after considering that OPPs can be dynamically added/removed. However writes to the sysfs files still behave as expected. v2: Use 64b math to avoid potential 32b overflow Signed-off-by: Rob Clark <robdclark@chromium.org> Link: https://lore.kernel.org/r/20211120200103.1051459-3-robdclark@gmail.com Signed-off-by: Rob Clark <robdclark@chromium.org>
2021-11-28drm/msm: Increase gpu boost intervalAkhil P Oommen1-1/+1
Currently, we boost gpu freq after 25ms of inactivity. This regresses some of the 30 fps usecases where the workload on gpu (at 33ms internval) is very small which it can finish at the lowest OPP before the deadline. Lets increase this inactivity threshold to 50ms (same as the current devfreq interval) to fix this.

But later was applied using 'cat nomodeset.mbox | dim apply-branch' on a machine with 'diff.noprefix false'. And command 'git am --scissors -3' as used by the dim tool doesn't handle that case well, since the 3-way merge wrongly resolves the path for new file drivers/gpu/drm/drm_nomodeset.c as gpu/drm/drm_nomodeset.c instead.

2021-11-27iio: expose shared parameter in IIO_ENUM_AVAILABLEAntoniu Miclaus20-36/+28
The shared parameter should be configurable based on its usage, and not constrained to IIO_SHARED_BY_TYPE. This patch aims to improve the flexibility in using the IIO_ENUM_AVAILABLE define and avoid redefining custom iio enums that expose the shared parameter. An example is the ad5766.c driver where IIO_ENUM_AVAILABLE_SHARED was defined in order to achieve `shared` parameter customization. The current state of the IIO_ENUM_AVAILABLE implementation will imply similar redefinitions each time a driver will require access to the `shared` parameter. An example would be admv1013 driver which will require custom device attribute for the frequency translation modes: Quadrature I/Q mode and Intermediate Frequency mode.

2021-11-27iio: adc: stm32: fix null pointer on defer_probe errorOlivier Moysan1-1/+1
dev_err_probe() calls __device_set_deferred_probe_reason() on -EPROBE_DEFER error. If device pointer to driver core private structure is not initialized, an null pointer error occurs. This pointer is set on iio_device_register() call for iio device. dev_err_probe() must be called with the device which is probing. Replace iio device by its parent device.

2021-11-27drm: Move nomodeset kernel parameter to the DRM subsystemJavier Martinez Canillas14-45/+17
The "nomodeset" kernel cmdline parameter is handled by the vgacon driver but the exported vgacon_text_force() symbol is only used by DRM drivers. It makes much more sense for the parameter logic to be in the subsystem of the drivers that are making use of it. Let's move the vgacon_text_force() function and related logic to the DRM subsystem. While doing that, rename it to drm_firmware_drivers_only() and make it return true if "nomodeset" was used and false otherwise. This is a better description of the condition that the drivers are testing for.
