drm/rockchip: analogix: Convert to drm_output_color_format

2026-03-24T12:54:34Z

Now that we introduced a new drm_output_color_format enum to represent what DRM_COLOR_FORMAT_* bits were representing, we can switch to the new enum. The main difference is that while DRM_COLOR_FORMAT_ was a bitmask, drm_output_color_format is a proper enum. However, the enum was done is such a way than DRM_COLOR_FORMAT_X = BIT(DRM_OUTPUT_COLOR_FORMAT_X) so the transitition is easier. The only thing we need to consider is if the original code meant to use that value as a bitmask, in which case we do need to keep the bit shift, or as a discriminant in which case we don't.

drm/rockchip: vop2: Support setting custom background color

2026-03-18T09:59:57Z

The Rockchip VOP2 display controller allows configuring the background color of each video output port. Since a previous patch introduced the BACKGROUND_COLOR CRTC property, which defaults to solid black, make use of it when programming the hardware. Note the maximum precision allowed by the display controller is 10bpc, while the alpha component is not supported, hence ignored.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

drm/rockchip: dw_dp: Add DisplayPort support for rk3576

2026-02-21T22:13:42Z

The DisplayPort of the RK3576 is basically the same as that of the RK3588, but it operates in dual-pixel mode and also support MST. This patch only enable the SST output now.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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
