2025-02-25drm/msm: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2025-02-14drm/atomic: Let drivers decide which planes to async flipAndré Almeida
Currently, DRM atomic uAPI allows only primary planes to be flipped asynchronously. However, each driver might be able to perform async flips in other different plane types. To enable drivers to set their own restrictions on which type of plane they can or cannot flip, use the existing atomic_async_check() from struct drm_plane_helper_funcs to enhance this flexibility, thus allowing different plane types to be able to do async flips as well. Create a new parameter for the atomic_async_check(), `bool flip`. This parameter is used to distinguish when this function is being called from a plane update from a full page flip. In order to prevent regressions and such, we keep the current policy: we skip the driver check for the primary plane, because it is always allowed to do async flips on it.

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>

2023-09-09drm/msm: 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 msm drm drivers from always returning zero in the remove callback to the void returning variant.

2022-09-18drm/msm: lookup the ICC paths in both mdp5/dpu and mdss devicesDmitry Baryshkov
The commit 6874f48bb8b0 ("drm/msm: make mdp5/dpu devices master components") changed the MDP5 driver to look for the interconnect paths in the MDSS device rather than in the MDP5 device itself. This was left unnoticed since on my testing devices the interconnects probably didn't reach the sync state. Rather than just using the MDP5 device for ICC path lookups for the MDP5 devices, introduce an additional helper to check both MDP5/DPU and MDSS nodes. This will be helpful for the MDP5->DPU conversion, since the driver will have to check both nodes.
