drm/imx: parallel-display: check return value of devm_drm_bridge_add() in imx_pd_probe()

2026-03-12T11:09:08+00:00

[ Upstream commit c5f8658f97ec392eeaf355d4e9775ae1f23ca1d3 ] Return the value of devm_drm_bridge_add() in order to propagate the error properly, if it fails due to resource allocation failure or bridge registration failure. This ensures that the probe function fails safely rather than proceeding with a potentially incomplete bridge setup.

Make sure to drop the reference taken to the DDC device during probe on probe failure (e.g. probe deferral) and on driver unbind.

drm/imx/ipuv3: Fix dumb-buffer allocation for non-RGB formats

2025-11-13T13:56:17+00:00

Align pitch to multiples of 8 pixels for bpp values that do not map to RGB formats. The call to drm_driver_color_mode_format() fails with DRM_INVALID_FORMAT in these cases. Fall back to manually computing the pitch alignment from which drm_mode_size_dumb() can compute the correct pitch. Fixes userspace that allocates dumb buffers for YUV formats, where bpp equals 12. A common example is the IGT kms_getfb test. v2: - ignore width in calculation Suggested-by: Dmitry Baryshkov Signed-off-by: Thomas Zimmermann Fixes: b1d0e470f881 ("drm/imx/ipuv3: Compute dumb-buffer sizes with drm_mode_size_dumb()") Cc: Thomas Zimmermann Cc: Philipp Zabel Cc: Shawn Guo Cc: Sascha Hauer Cc: Pengutronix Kernel Team Cc: Fabio Estevam Cc: dri-devel@lists.freedesktop.org Cc: imx@lists.linux.dev Cc: linux-arm-kernel@lists.infradead.org Tested-by: Philipp Zabel Reviewed-by: Philipp Zabel Link: https://patch.msgid.link/20251104153832.189666-1-tzimmermann@suse.de

drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.

drm/imx: parallel-display: add the bridge before attaching it

Invoking drm_bridge_add() is good practice, so add it to this driver.

drm/imx: parallel-display: convert to devm_drm_bridge_alloc() API

2025-10-30T15:55:19+00:00

This is the new API for allocating DRM bridges. This conversion was missed during the initial conversion of all bridges to the new API. Thus all kernels with commit 94d50c1a2ca3 ("drm/bridge: get/put the bridge reference in drm_bridge_attach/detach()") and using this driver now warn due to drm_bridge_attach() incrementing the refcount, which is not initialized without using devm_drm_bridge_alloc() for allocation. To make the conversion simple and straightforward without messing up with the drmm_simple_encoder_alloc(), move the struct drm_bridge from struct imx_parallel_display_encoder to struct imx_parallel_display. Also remove the 'struct imx_parallel_display *pd' from struct imx_parallel_display_encoder, not needed anymore.
