The checks on the existence of bridge->encoder in the implementation of drm_bridge_funcs::attach() is not necessary, as it has already been checked in the drm_bridge_attach() function call by previous bridge or KMS driver. The drm_bridge_attach() will quit with a negative error code returned if it fails for some reasons, hence, it is guaranteed that the .encoder member of the drm_bridge instance is not NULL when various bridge attach functions are called. Remove the redundant checking codes "if (!bridge->encoder) { ... }". Reviewed-by:Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by:

Udl's struct udl_connector is an empty wrapper around struct drm_connector. Remove it. Allocate the connector as part of struct udl_device and inline the init function into its only caller. v2: - fix return value in udl_modeset_init() (Dan) Signed-off-by:
-
Thomas Zimmermann authored
Provide separate implementations of .get_modes() and .detect_ctx() from struct drm_connector. Switch to struct drm_edid. Udl's .detect() helper used to fetch the EDID from the adapter and the .get_modes() helper provided display modes from the data. But this relied on the DRM helpers to call the functions in the correct order. When no EDID could be retrieved, .detect() regularly printed a warning to the kernel log. Switching to the new helpers around struct drm_edid separates both from each other. The .get_modes() helper now fetches the EDID by itself and the .detect_ctx() helper only tests for its presence. The patch does a number of things to implement this. - Move udl_get_edid_block() to udl_edid.c and rename it to udl_read_edid_block(). Then use the helper to implement probing in udl_probe_edid() and reading in udl_edid_read(). The latter helper is build on top of DRM helpers. - Replace the existing code in .get_modes() and .detect() with udl's new EDID helpers. The new code behaves like DRM's similar DDC-based helpers. Instead of .detect(), udl now implements .detect_ctx(). - Remove the edid data from struct udl_connector. The field cached the EDID data between calls to .detect() and .get_modes(), but is now unused. v3: - implement udl_probe_edid() with memchr_inv() (Jani) v2: - implement udl_probe_edid() within udl - reword commit description Signed-off-by:

Protect the code in udl_get_edid_block() with drm_dev_enter() and drm_dev_exit(), so that all callers automatically invoke it. The function uses hardware resources, which can be hot-unplugged at any time. The other code in udl_connector_detect() does not use the resources of the hardware device and therefore does not require protection. This change will allow to use udl_get_edid_block() in various contexts easily. Signed-off-by:

Each layer in the DPU has a 40-bit base address register, which indicates start of frame buffer data for that layer. Komeda driver does not set its DMA mask, which makes it 32-bit by default which does not use the entire available possible supported by the DPU. Update the DMA mask to align with DPU Architecture v1.0 spec. Signed-off-by:

The komeda driver prints a pretty verbose log in komeda_pipeline_dump() detailing the components of each of the two pipelines. This gets printed multiple times during boot as komeda EPROBE_DEFERs waiting for the remote bridge drivers to come up. Move this log to after this has happened indicating that the printed pipeline is actually completely up. Signed-off-by:

Since commit 4cfe5cc0 ("drm/arm/komeda: Remove component framework and add a simple encoder"), the devm_drm_of_get_bridge() call happens regardless of whether any remote nodes are available on the pipeline. Fix this by moving the bridge attach to its own function and calling it conditional on there being an output link.

There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_for_completion_timeout() causing patterns like: timeout = wait_for_completion_timeout(...) if (!timeout) return -ETIMEDOUT; with all kinds of permutations. Check the return value directly to drop 'timeout' which also fixes its wrong type. Signed-off-by:
