Subject: [PATCH v2 00/10] media: Introduce video device state management
Hi,
This patch series introduces state management for video devices.
Currently, V4L2 subdevices have a well-established state management
system [1] that allows the framework to store the subdevice state
at a central location.
Video devices however lack this, leading to inconsistent state handling
across drivers and making it difficult to implement features like
hardware multiplexing in complex media pipelines [2].
The series is composed of three parts:
- Core Infrastructure (PATCH 1-4)
Introduces the basic state structure, try state support,
initialization callbacks, and driver helpers
- Framework Integration (PATCH 5-7)
Integrates state passing through the ioctl wrappers and driver
implementations
- Driver Examples (PATCH 8-10)
Use the state to store formats in TI J721E CSI2RX and Rockchip
RKISP1 drivers
This should also provide a foundation for drivers to extend or subclass
the state structure with device-specific variables in future.
I have tested capture and format negotiation with the converted drivers
on SK AM62A (j721e-csi2rx) and Debix Model A (rkisp1).

Changes in v2:
- Drop RFC tag
- Rebase on top of latest media tree, that includes multiple changes by
Jacopo and Laurent, which removes all usage of passing v4l2_fh through
the opaque pointer in ioctl implementations, replacing it with a NULL
pointer
- Allocate the state dynamically, and free it when done with the device
or the filehandle
- Introduce an init_state callback so that drivers can initialize the
state after allocation
- Pass the video device state (as an explicitly typed pointer) to all
ioctl implemenation across all drivers
- Split the single patch introducing video device state into separate
patches each making a single logical change before the state is
actually passed to the drivers in PATCH 7
- In drivers, use a helper to access the current format from the state
- Move the queue busy check back to the drivers, as some codecs and VBI
devices may support changing formats, so the framework shouldn't
return -EBUSY
- Drop pixel format info and configuration storage from rkisp1 internal
strucutre, and calculate them on the fly
- Fix other review comments from Sakari, Laurent and Jacopo, except
those around dropping the enum and using try_fmt hook to update only
the state, and s_fmt hook to update hardware registers
