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

media: iris: Introduce vpu ops for vpu4 with necessary hooks

2026-01-20T15:22:24+00:00

Add power sequence for vpu4 by reusing from previous generation wherever possible. Hook up vpu4 op with vpu4 specific implemtation or resue from earlier generation wherever feasible, like clock calculation in this case.

media: iris: Move vpu35 specific api to common to use for vpu4

2026-01-20T15:22:24+00:00

Some of the sequence and calculations for vpu4 is identical to vpu35, namely power sequence for vpu controller and the clock frequency calculation. Move those to common file that can be shared for both vpu35 and vpu4. This patch prepares for power sequence for vpu4 which is added in subsequent patch.

media: iris: Move vpu register defines to common header file

2026-01-20T15:22:24+00:00

Some of vpu4 register defines are common with vpu3x. Move those into the common register defines header. This is done to reuse the defines for vpu4 in subsequent patch which enables the power sequence for vpu4.

vpu4 needs an additional configuration with respect to CP regions. Make the CP configuration as array such that the multiple configuration can be managed per platform.

media: iris: Add support for multiple clock sources

2026-01-20T15:22:24+00:00

vpu4 depends on more than one clock source. Thus far hardware versions up to vpu3x have been clocked by a single source. This adds support for multiple clocks by, - Adding a lookup table - Configuring OPP table for video device with different video clocks - Setting OPP for multiple clocks during dev_pm_opp_set_opp() This patch extends the support for multiple clocks in driver, which would be used in subsequent patch for kaanapali, when the platform data is prepared.
