2023-12-04Revert "drm/atomic: Add solid fill data to plane state dump"Dmitry Baryshkov
This reverts commit e86413f5442ee094e66b3e75f2d3419ed0df9520. Although the Solid Fill planes patchset got all reviews and acknowledgements, it doesn't fulfill requirements for the new uABI. It has neither corresponding open-source userspace implementation nor the IGT tests coverage. Reverting this patchset until userspace obligations are fulfilled.

2023-12-04drm/bridge: migrate bridge_chains to per-encoder fileDmitry Baryshkov
Instead of having a single file with all bridge chains, list bridges under a corresponding per-encoder debugfs directory. While we are at it, also slightly improve the formatting of the bridge data: split a single line entry into multiple lines, include the symbol name of the bridge funcs and add the textual representation of the bridge ops.

2023-12-04iio: add modifiers for A and B ultraviolet lightJavier Carrasco
Currently there are only two modifiers for ultraviolet light: a generic one for any ultraviolet light (IIO_MOD_LIGHT_UV) and one for deep ultraviolet (IIO_MOD_LIGHT_DUV), which is also referred as ultraviolet C (UV-C) band and covers short-wave ultraviolet. There are still no modifiers for the long-wave and medium-wave ultraviolet bands. These two bands are the main components used to obtain the UV index on the Earth's surface.

2023-12-04usb: core: Allow subclassed USB drivers to override usb_choose_configuration()Douglas Anderson
For some USB devices we might want to do something different for usb_choose_configuration(). One example here is the r8152 driver where we want to end up using the vendor driver with the preferred interface. The r8152 driver tried to make things work by implementing a USB generic_subclass driver and then overriding the normal config selection after it happened. This is less than ideal and also caused breakage if someone deauthorized and re-authorized the USB device because the USB core ended up going back to it's default logic for choosing the best config. I made an attempt to fix this [1] but it was a bit ugly. Let's do this better and allow USB generic_subclass drivers to override usb_choose_configuration(). [1] https://lore.kernel.org/r/20231130154337.1.Ie00e07f07f87149c9ce0b27ae4e26991d307e14b@changeid Suggested-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Douglas Anderson <dianders@chromium.org> Reviewed-by: Alan Stern <stern@rowland.harvard.edu> Link: https://lore.kernel.org/r/20231201102946.v2.2.Iade5fa31997f1a0ca3e1dec0591633b02471df12@changeid Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2023-12-04spi: spl022: fix sleeping in interrupt contextMark Brown
Merge series from Nam Cao <namcao@linutronix.de>: While running the spl022, I got the following warning: BUG: sleeping function called from invalid context at drivers/spi/spi.c:1428 This is because between spi transfers, spi_transfer_delay_exec() (who may sleep if the delay is >10us) is called in interrupt context. This is a problem for anyone who runs this driver and need more than 10us delay. Patch 1 adds an error reporting mechanism, needed by patch 2 who switch to use the default spi_transfer_one_message(), which fix the problem. The series is tested with polling transfer mode and interrupt transfer mode. I can't test the DMA mode, so some help testing here is very appreciated.

The subdev .init_cfg() operation is affected by two issues: - It has long been extended to initialize a whole v4l2_subdev_state instead of just a v4l2_subdev_pad_config, but its name has stuck around. - Despite operating on a whole subdev state and not being directly exposed to the subdev users (either in-kernel or through the userspace API), .init_cfg() is categorized as a subdev pad operation. This participates in making the subdev API confusing for new developers. Fix it by renaming the operation to .init_state(), and make it a subdev internal operation.

2023-12-01block: bio-integrity: directly map user buffersKeith Busch
Passthrough commands that utilize metadata currently need to bounce the user space buffer through the kernel. Add support for mapping user space directly so that we can avoid this costly overhead. This is similar to how the normal bio data payload utilizes user addresses with bio_map_user_iov(). If the user address can't directly be used for reason, like too many segments or address unalignement, fallback to a copy of the user vec while keeping the user address pinned for the IO duration so that it can safely be copied on completion in any process context.

2023-12-02drm/atomic: Loosen FB atomic checksJessica Zhang
Loosen the requirements for atomic and legacy commit so that, in cases where pixel_source != FB, the commit can still go through. This includes adding framebuffer NULL checks in other areas to account for FB being NULL when non-FB pixel sources are enabled. To disable a plane, the pixel_source must be NONE or the FB must be NULL if pixel_source == FB.
