media: ipu-bridge: Keep the clock-noncontinuous property name out of rodata

2026-10-03T16:24:42+00:00

The software nodes ipu-bridge registers on a successful init are never
unregistered. There is no module_exit and no remove hook, and every
software_node_unregister_node_group() call sits on an error unwind label
inside ipu_bridge_init(), so on success the nodes stay registered and
readable after the module is unloaded, which a later rebind relies on.

Nothing reachable from a registered node may therefore point into the
module image. PROPERTY_ENTRY_BOOL() stores a pointer to its name, so the
"clock-noncontinuous" string literal leaves the surviving node carrying a
dangling property name once ipu-bridge is gone.

Add the name to struct ipu_property_names, which is copied by value into
each struct ipu_sensor, and use that copy, as every other endpoint
property name already does.

media: ipu6: Add PCI ID for IPU8

2026-10-01T11:02:31+00:00

Add the IPU8 PCI ID and probe wiring. IPU8 reuses the IPU7P5 buttress
register map (unvalidated against IPU8's hardware spec) but needs its
own default control ratio (0x10), so add dedicated
ipu8_{isys,psys}_buttress_ctrl structs instead of reusing IPU7's.

media: i2c/platform: add V4L2_SET_EDID_HPD_LOW_JIFFIES define

2026-09-23T12:54:49+00:00

HDMI receivers need to pull the HPD pin low for at least 100 ms to
indicate that a new EDID is available. In practice, HZ / 7 is a good
value for that as this gives enough slack for video sources to detect
this situation. Due to clock frequency differences and imprecise
video source implementations using exactly 100 ms (or even a bit more)
may still cause this to be missed by the video source.

Over many years HZ / 7 (143 ms) has proven to be a good safe value
for this.

Add a new #define to v4l2-dv-timings.h and modify the various drivers
that do this to use this define. Most already used HZ / 7, but some
were a bit longer.

media: v4l2-ctrls: do nothing if controls[0] == NULL in cluster functions

2026-09-23T12:54:49+00:00

The V4L2 control framework is designed to allow drivers to instantiate
controls and clusters without checking for errors after each call,
checking hdl->error only once at the end.

However, if allocating the master control (controls[0]) fails, e.g. due to
memory allocation failure, v4l2_ctrl_cluster() triggers a WARNING:

      ncontrols == 0 || controls[0] == NULL
      WARNING: drivers/media/v4l2-core/v4l2-ctrls-core.c:2525 at v4l2_ctrl_cluster

Additionally, v4l2_ctrl_auto_cluster() attempts to dereference
master->minimum without checking if controls[0] is NULL, leading to a
NULL pointer dereference when master control creation fails.

Update both v4l2_ctrl_cluster() and v4l2_ctrl_auto_cluster() to silently
return if controls[0] is NULL, preserving the design that control
creation errors are caught at the end when the driver checks hdl->error.
Also update function documentation in include/media/v4l2-ctrls.h.

media: v4l2-subdev: Add struct v4l2_subdev_client_info pointer to pad ops

2026-09-17T09:14:55+00:00

Add a pointer to const struct v4l2_subdev_client_info to the get_fmt,
set_fmt, get_selection and set_selection sub-device pad ops. The client
info struct will soon be used to differentiate UAPI based on client
capabilities.

media: v4l2-subdev: Move op check to sub-device op wrappers

2026-09-17T09:14:54+00:00

In anticipation of performing work for sub-device operation when the
driver doesn't implement one, move the check of operation existence to the
wrapper itself.

No functional change intended.

media: v4l2-subdev: Move subdev client capabilities into a new struct

2026-09-17T09:14:54+00:00

Add struct v4l2_subdev_client_info to hold sub-device client capability
bits that used to be stored in the client_caps field of struct
v4l2_subdev_fh.

The intent is to enable passing this struct to sub-device pad operation
callbacks for capability information. The main reason why this is a new
struct instead of a u64 field is that modifying the callback arguments
requires touching almost every sub-device driver and that is desirable to
avoid in the future, should more than the client capability bits need to
be known to the callbacks.
