2025-05-16gpu: ipu-v3: Switch to irq_find_mapping()Jiri Slaby (SUSE)
irq_linear_revmap() is deprecated, so remove all its uses and supersede them by an identical call to irq_find_mapping().

2025-05-16gpu: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory.

2024-06-26gpu: ipu-v3: pre: don't use fixed timeout when waiting for safe windowLucas Stach
The timeout when waiting for the PRE safe window is rather short, as normally we would only need to wait a few dozen usecs for the problematic scanline region to pass and we don't want to spin too long in case something goes wrong. This however mixes badly with preemption, as we can easily get scheduled away from the CPU for a longer time than our timeout, in which case we would hit a spurious timeout and wrongly skip the PRE update. Instead of disabling preemption across the wait loop, potentially impacting the overall system latency, use a wait loop with a fixed max number of iterations, so time spent away from the CPU is not accounted against the timeout budget.

2024-06-26gpu: ipu-v3: pre: add dynamic buffer layout reconfigurationLucas Stach
imx-drm doesn't mandate a modeset when the framebuffer modifier changes, but currently the tile prefetch and resolve (TPR) configuration of the PRE is only set up on the initial modeset. As the TPR configuration is double buffered, same as all the other PRE states, we can support dynamic reconfiguration of the buffer layout from one frame to another. As switching between (super-)tiled and linear prefetch needs to touch the CTRL register make sure to do the reconfiguration inside the safe window.

2024-05-27gpu: ipu-v3: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert the ipu-v3 platform drivers from always returning zero in the remove callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

Some of these dependencies used to be sensible when only a small part of the platforms supported by ARCH=arm could be compiled together in a single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard for kernel options incompatible with a multiplatform image.

2022-02-17media: v4l2-mediabus: Use structures to describe bus configurationLaurent Pinchart
The media bus configuration is specified through a set of flags, some of which being mutually exclusive. This doesn't scale to express more complex configurations. Improve the API by replacing the single flags field in v4l2_mbus_config by a union of v4l2_mbus_config_* structures. The flags themselves are still used in those structures, so they are kept here. Drivers are however updated to use structure fields instead of flags when already possible.

2021-05-10drm/imx: Add 8 pixel alignment fixSebastian Reichel
Some standard resolutions like 1366x768 do not work properly with i.MX6 SoCs, since the horizontal resolution needs to be aligned to 8 pixels (so 1360x768 or 1368x768 would work). This patch allocates framebuffers allocated to 8 pixels. The extra time required to send the extra pixels are removed from the blank time. In order to expose the correct display size to userspace, the stride is increased without increasing the width. Without this patch systems with this display resolution hang indefinitely during boot up.

Use a bit-mask of EOF irqs to determine when all required idmac channel EOFs have been received for a tile conversion, and only do tile completion processing after all EOFs have been received. Otherwise it was found that a conversion would stall after the completion of a tile and the start of the next tile, because the input/read idmac channel had not completed and entered idle state, thus locking up the channel when attempting to re-start it for the next tile.

2019-08-19gpu: ipu-v3: image-convert: fix image downsize coefficients and tiling ↵Philipp Zabel
calculation This patch effectively reverts commit 912bbf7e9ca4 ("gpu: ipu-v3: image-convert: Fix image downsize coefficients") and replaces it with a different solution based on the preceding patches. The previous fix tried to solve the problem of intermediate tile size between IC downsizing and main processing sections not being limited to 1024 pixels by downsizing the input image to a smaller intermediate size in the downsizing box filter. This causes unnecessary blurring, especially for scaling factors close to 1. Now that the seam position calculation makes sure that the 1024 pixel intermediate tile size limit is not exceeded, calculate the number of tiles from the maximum of intermediate size and output size and avoid unnecessary downsizing.

In that case an empty interval out_start == out_end is being passed to find_best_seam, which looks for a seam out_start <= x < out_end. Also reduce the interval for all but the left column / top row, to avoid returning position 0 as best fit. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
