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>
2024-10-21drm/mediatek: Implement OF graphs support for display pathsAngeloGioacchino Del Regno
It is impossible to add each and every possible DDP path combination for each and every possible combination of SoC and board: right now, this driver hardcodes configuration for 10 SoCs and this is going to grow larger and larger, and with new hacks like the introduction of mtk_drm_route which is anyway not enough for all final routes as the DSI cannot be connected to MERGE if it's not a dual-DSI, or enabling DSC preventively doesn't work if the display doesn't support it, or others. Since practically all display IPs in MediaTek SoCs support being interconnected with different instances of other, or the same, IPs or with different IPs and in different combinations, the final DDP pipeline is effectively a board specific configuration. Implement OF graphs support to the mediatek-drm drivers, allowing to stop hardcoding the paths, and preventing this driver to get a huge amount of arrays for each board and SoC combination, also paving the way to share the same mtk_mmsys_driver_data between multiple SoCs, making it more straightforward to add support for new chips. Note that the OVL_ADAPTOR software component driver needs relatively big changes in order to fully support OF Graphs (and more SoCs anyway) and such changes will come at a later time. As of now, the mtk_disp_ovl_adaptor driver takes the MERGE components (for example, on mt8195, merge 1 to 4) dynamically so, even though later updates to the ovl-adaptor driver will *not* require bindings changes, the merge1-4 will be temporarily omitted in the graph for the MT8195 SoC. This means that an example graph for this SoC looks like: mdp_rdma (0 ~ 7) -> padding (0 ~ 7) -> ethdr -> merge5 and the resulting path in this driver will be `ovl_adaptor -> merge5` Later updates to the ovl adaptor will expand it to support more SoCs and, in turn, to also fully support graphs.

2024-06-28drm/mediatek: dpi/dsi: Fix possible_crtcs calculationMichael Walle
mtk_find_possible_crtcs() assumes that the main path will always have the CRTC with id 0, the ext id 1 and the third id 2. This is only true if the paths are all available. But paths are optional (see also comment in mtk_drm_kms_init()), e.g. the main path might not be enabled or available at all. Then the CRTC IDs will shift one up, e.g. ext will be 0 and the third path will be 1. To fix that, dynamically calculate the IDs by the presence of the paths. While at it, make the return code a signed one and return -ENODEV if no path is found and handle the error in the callers.

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.

2022-07-04drm/mediatek: dpi: Implement a CK/DE pol toggle in SoC configGuillaume Ranquet
Dp_intf does not support CK/DE polarity because the polarity information is not used for eDP and DP while dp_intf is only for eDP and DP. Therefore, we add a bit of flexibility to support SoCs without CK/DE pol support.

2022-04-22drm/mediatek: dpi: Use mt8183 output formats for mt8192Nícolas F. R. A. Prado
The configuration for mt8192 was incorrectly using the output formats from mt8173. Since the output formats for mt8192 are instead the same ones as for mt8183, which require two bus samples per pixel, the pixelclock and DDR edge setting were misconfigured. This made external displays unable to show the image. Fix the issue by correcting the output format for mt8192 to be the same as for mt8183, fixing the usage of external displays for mt8192.
