drm/imx: parallel-display: Switch to atomic_create_state

2026-06-22T09:24:41+00:00

The drm_bridge_funcs.atomic_reset callback and its drm_atomic_helper_bridge_reset() helper are deprecated. Switch to the atomic_create_state callback and its drm_atomic_helper_bridge_create_state() counterpart.

drm/bridge: Move legacy bridge driver out of imx directory for multi-platform use

2026-04-09T12:10:21+00:00

As suggested by Dmitry, the DRM legacy bridge driver can be pulled out of imx/ subdir for multi-platform use. The driver is also renamed to make it more generic and suitable for platforms other than i.MX.

drm/imx: parallel-display: Prefer bus format set via legacy "interface-pix-fmt" DT property

2026-03-13T15:26:25+00:00

Prefer bus format set via legacy "interface-pix-fmt" DT property over panel bus format. This is necessary to retain support for DTs which configure the IPUv3 parallel output as 24bit DPI, but connect 18bit DPI panels to it with hardware swizzling. This used to work up to Linux 6.12, but stopped working in 6.13, reinstate the behavior to support old DTs.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

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

2026-02-20T12:37:03+00:00

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.
