* drm/imx: Add i.MX8qxp Display Controller KMSLiu Ying2025-05-149-2/+1340
| | | | | | | | | | | | | | | | i.MX8qxp Display Controller(DC) is comprised of three main components that include a blit engine for 2D graphics accelerations, display controller for display output processing, as well as a command sequencer. Add kernel mode setting support for the display controller part with two CRTCs and two primary planes(backed by FetchLayer and FetchWarp respectively). The registers of the display controller are accessed without command sequencer involved, instead just by using CPU. The command sequencer is supposed to be used by the blit engine.

| | | | | | | | | | | | | | | i.MX8qxp Display Controller pixel engine consists of all processing units that operate in the AXI bus clock domain. Add drivers for ConstFrame, ExtDst, FetchLayer, FetchWarp and LayerBlend units, as well as a pixel engine driver, so that two displays with primary planes can be supported. The pixel engine driver and those unit drivers are components to be aggregated by a master registered in the upcoming DRM driver.

* drm/bridge: Add encoder parameter to drm_bridge_funcs.attachMaxime Ripard2025-03-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.

| * Get rid of 'remove_new' relic from platform driver structLinus Torvalds2024-12-018-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper code should always be selected by the driver that needs it, for the convenience of the final user configuring a kernel. The user who configures a kernel should not need to know which helpers are needed for the driver he is interested in. Making a driver depend on helper code means that the user needs to know which helpers to enable first, which is very user-unfriendly.

* | drm: Make drivers depends on DRM_DW_HDMIMaxime Ripard2024-03-281-2/+3
|/ | | | | | | | | | | | | | | | | | | | | DRM_DW_HDMI has a number of dependencies that might not be enabled. However, drivers were used to selecting it while not enforcing the DRM_DW_HDMI dependencies. This could result in Kconfig warnings (and further build breakages) such as: Kconfig warnings: (for reference only) WARNING: unmet direct dependencies detected for DRM_DW_HDMI Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && DRM_DISPLAY_HELPER [=n] Selected by [m]: - DRM_SUN8I_DW_HDMI [=m] && HAS_IOMEM [=y] && DRM_SUN4I [=m] Reported-by: kernel test robot <[email protected]> Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/ Acked-by: Jani Nikula <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Maxime Ripard <[email protected]>

| | | | | | | | | | | | | Use preferred device_get_match_data() instead of of_match_device() to get the driver match data in a single step. With this, adjust the includes to explicitly include the correct headers. That also serves as preparation to remove implicit includes within the DT headers (of_device.h in particular).
