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>

2023-09-21drm/hisilicon/kirin: Call drm_atomic_helper_shutdown() at shutdown/unbind timeDouglas Anderson
Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time and at driver unbind time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart and at driver remove (or unbind) time comes straight out of the kernel doc "driver instance overview" in drm_drv.c. I have attempted to put this in the right place at unbind time. In most other DRM drivers the call is made right after the call to drm_kms_helper_poll_fini(), so I've put it there. That means that this call will also be made in the case that we hit errors in bind, since kirin_drm_kms_cleanup() is called both in the bind error path and in unbind. I believe this is harmless even though it's not needed in the bind error path. For handling shutdown, we rely on the common technique of seeing if the drvdata is NULL to know whether we need to call drm_atomic_helper_shutdown(). This makes it important to make sure that the drvdata is NULL if bind failed or if unbind was called. We don't need the actual check for NULL and we'll rely on the patch ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop").

2023-09-21drm: Call drm_atomic_helper_shutdown() at shutdown time for misc driversDouglas Anderson
Based on grepping through the source code these drivers appear to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c. All of the drivers in this patch were fairly straightforward to fix since they already had a call to drm_atomic_helper_shutdown() at remove/unbind time but were just lacking one at system shutdown. The only hitch is that some of these drivers use the component model to register/unregister their DRM devices. The shutdown callback is part of the original device. The typical solution here, based on how other DRM drivers do this, is to keep track of whether the device is bound based on drvdata. In most cases the drvdata is the drm_device, so we can just make sure it is NULL when the device is not bound. In some drivers, this required minor code changes. To make things simpler, drm_atomic_helper_shutdown() has been modified to consider a NULL drm_device as a noop in the patch ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop").

2023-07-21drm: Explicitly include correct DT includesRob Herring
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. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-06-08drm/hisilicon: 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 (mostly) ignored 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. Trivially convert the hisilicon drm drivers from always returning zero in the remove callback to the void returning variant.

2022-09-20drm/hisilicon: Add depends on MMURandy Dunlap
The Kconfig symbol depended on MMU but was dropped by the commit acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu") because it already had as a dependency ARM64 that already selects MMU. But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built if COMPILE_TEST is enabled") allowed the driver to be built for non-ARM64 when COMPILE_TEST is set but that could lead to unmet direct dependencies and linking errors. Prevent a kconfig warning when MMU is not enabled by making DRM_HISI_HIBMC depend on MMU.

Without proper care and an agreement between how DSI hosts and devices drivers register their MIPI-DSI entities and potential components, we can end up in a situation where the drivers can never probe. Most drivers were taking evasive maneuvers to try to workaround this, but not all of them were following the same conventions, resulting in various incompatibilities between DSI hosts and devices.
