* drm/imx: move IPUv3 driver into separate subdirectoryLucas Stach2022-12-161-770/+0
| | | | | | | | | | | | | The IPUv3 and DCSS driver are two totally separate DRM drivers. Having one of them live in the drivers/gpu/drm/imx toplevel directory and the other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver into its own subdirectory to make the separation more clear.

| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | When CONFIG_OF is disabled, building with 'make W=1' produces warnings about out of bounds array access: drivers/gpu/drm/imx/imx-ldb.c: In function 'imx_ldb_set_clock.constprop': drivers/gpu/drm/imx/imx-ldb.c:186:8: error: array subscript -22 is below array bounds of 'struct clk *[4]' [-Werror=array-bounds] Add an error check before the index is used, which helps with the warning, as well as any possible other error condition that may be triggered at runtime. The warning could be fixed by adding a Kconfig depedency on CONFIG_OF, but Liu Ying points out that the driver may hit the out-of-bounds problem at runtime anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Component driver structures allocated with devm_kmalloc() in bind() are freed automatically after unbind(). Since the contained drm structures are accessed afterwards in drm_mode_config_cleanup(), move the allocation into probe() to extend the driver structure's lifetime to the lifetime of the device. This should eventually be changed to use drm resource managed allocations with lifetime of the drm device. We also need to ensure that all componets are available during the unbind() so we need to call component_unbind_all() before we free non-devres resources like planes. Note this patch fixes the the use after free bug but introduces a possible boot loop issue. The issue is triggered if the HDMI support is enabled and a component driver always return -EPROBE_DEFER, see discussion [1] for more details.

* drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart2020-02-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <[email protected]> Reviewed-by: Boris Brezillon <[email protected]> Acked-by: Sam Ravnborg <[email protected]> Reviewed-by: Tomi Valkeinen <[email protected]> Tested-by: Sebastian Reichel <[email protected]> Reviewed-by: Sebastian Reichel <[email protected]> Acked-by: Daniel Vetter <[email protected]> Signed-off-by: Tomi Valkeinen <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LVDS signal integrity is only guaranteed when the correct enable sequence (first IPU DI, then LDB) is used. If the LDB display output was active before the imx-drm driver is loaded (like when a bootsplash was active) the DI will be disabled by the full IPU reset we do when loading the driver. The LDB control registers are not part of the IPU range and thus will remain unchanged. This leads to the LDB still being active when the DI is getting enabled, effectively reversing the required enable sequence. Fix this by also disabling the LDB on driver bind.
