drm/imx/tve: fix probe device leak

2026-02-06T15:48:26+00:00

commit e535c23513c63f02f67e3e09e0787907029efeaf upstream. 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: Use IRQF_NO_AUTOEN flag in request_irq()

2024-12-09T09:32:00+00:00

[ Upstream commit 40004709a3d3b07041a473a163ca911ef04ab8bd ] disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.

drm/imx/ipuv3: do not return negative values from .get_modes()

drm/imx/ipuv3: ipuv3-plane: reuse local variable height in atomic_update

2023-07-28T15:25:31+00:00

Use the already existing local variable height = drm_rect_height() >> 16 to replace other occurrences of the same value.

drm/imx/ipuv3: Fix front porch adjustment upon hactive aligning

2023-07-28T15:20:26+00:00

When hactive is not aligned to 8 pixels, it is aligned accordingly and hfront porch needs to be reduced the same amount. Unfortunately the front porch is set to the difference rather than reducing it. There are some Samsung TVs which can't cope with a front porch of instead of 70.

drm: Drop ARCH_MULTIPLATFORM from dependencies

2023-03-14T11:57:22+00:00

Some of these dependencies used to be sensible when only a small part of the platforms supported by ARCH=arm could be compiled together in a single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard for kernel options incompatible with a multiplatform image. See commit 84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more details.

drm/imx: move IPUv3 driver into separate subdirectory

2022-12-16T17:40:29+00:00

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.
