Remove cleanup of the register definitions from the TODO file. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

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

media: staging/ipu7: Fix the loop bound in l2 table alloc

2026-01-13T11:47:55Z

This patch fixes the incorrect loop bound in alloc_l2_pt(). When initializing L2 page table entries, the loop was incorrectly using ISP_L1PT_PTES instead of ISP_L2PT_PTES though the ISP_L1PT_PTES is equal to ISP_L2PT_PTES.

media: staging/ipu7: Update CDPHY register settings

2026-01-13T11:47:55Z

Some CPHY settings needs to updated according to the latest guide from SNPS. This patch program 45ohm for tuning resistance to fix CPHY problem and update the ITMINRX and GMODE for CPHY.

media: staging/ipu7: Call synchronous RPM suspend in probe failure

2026-01-13T11:47:55Z

If firmware authentication failed during driver probe, driver call an asynchronous API to suspend the psys device but the bus device will be removed soon, thus runtime PM of bus device will be disabled soon, that will cancel the suspend request, so use synchronous suspend to make sure the runtime suspend before disabling its RPM. IPU7 hardware has constraints that the PSYS device must be powered off before ISYS, otherwise it will cause machine check error.

media: staging/ipu7: Ignore interrupts when device is suspended

2026-01-13T11:47:55Z

IPU7 devices have shared interrupts with others. In some case when IPU7 device is suspended, driver get unexpected interrupt and invalid irq status 0xffffffff from ISR_STATUS and PB LOCAL_STATUS registers as interrupt is triggered from other device on shared irq line. In order to avoid this issue use pm_runtime_get_if_active() to check if IPU7 device is resumed, ignore the invalid irq status and use synchronize_irq() in suspend.

media: staging: ipu7: isys: Drop video_open() function

2025-10-29T13:07:01Z

The video_open() function is just a wrapper around v4l2_fh_open(). Replace it by the latter in the v4l2_file_operations. Signed-off-by: Laurent Pinchart Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: staging/ipu7: Use %pe format specifier

2025-10-17T09:31:16Z

The %pe format specifier is designed to print error pointers. It prints a symbolic error name (eg. -EINVAL) and it makes the code simpler by omitting PTR_ERR(). This patch fixes this cocci report: ./ipu7/ipu7-isys-csi-phy.c:311:23-30: WARNING: Consider using %pe to print PTR_ERR() ./ipu7/ipu7-isys-csi2.c:59:22-29: WARNING: Consider using %pe to print PTR_ERR() Signed-off-by: Ricardo Ribalda Acked-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: staging/ipu7: fix isys device runtime PM usage in firmware closing

2025-09-10T08:40:53Z

The PM usage counter of isys was bumped up when start camera stream (opening firmware) but it was not dropped after stream stop(closing firmware), it forbids system fail to suspend due to the wrong PM state of ISYS. This patch drop the PM usage counter in firmware close to fix it.
