199946731f [media] vsp1: clarify FCP dependency
The newly added FCP support in the vsp1 driver causes a link error
when CONFIG_RENESAS_FCP=m, since it's not reachable by built-in code:

drivers/media/built-in.o: In function `vsp1_remove':
:(.text+0xdeca0): undefined reference to `rcar_fcp_put'
drivers/media/built-in.o: In function `vsp1_probe':
:(.text+0xdef44): undefined reference to `rcar_fcp_get'

We already have a conditional dependency on FCP that requires
it for ARM64, so for all others we just have to prevent setting
RENESAS_VSP1=y when RENESAS_FCP=m by extending the FCP dependency.

Fixes: 94fcdf8297 ("[media] v4l: vsp1: Add FCP support")

af2e14bb3f [media] vsp1: use __maybe_unused for PM handlers
Building without CONFIG_PM results in a harmless warning from
slightly incorrect #ifdef guards:

drivers/media/platform/vsp1/vsp1_drv.c:525:12: error: 'vsp1_pm_runtime_resume' defined but not used [-Werror=unused-function]
drivers/media/platform/vsp1/vsp1_drv.c:516:12: error: 'vsp1_pm_runtime_suspend' defined but not used [-Werror=unused-function]

This removes the existing #ifdef and instead marks all four
PM functions as __maybe_unused.

Fixes: 1e6af546ee ("[media] v4l: vsp1: Implement runtime PM support")

Note that the memops functions now get a struct device pointer instead of

This code is now a lot cleaner.

f61d500820 [media] exynos4-is: Fix buffer release issue on fimc m2m video nodes
This fixes dropping ownership of buffers in the driver's stop_streaming

e0d80c8acc [media] s5p-mfc: improve v4l2_capability driver and card fields
According to the V4L2 documentation the driver and card fields should be
used to identify the driver and the device but the s5p-mfc driver fills
those field using the platform device name, which in turn is the name of
the device DT node.

So not only the filled information isn't correct but also the same values
are used in all the fields for both the encoder and decoder video devices.

Before this patch:

Driver Info (not using libv4l2):
        Driver name   : 11000000.codec
        Card type     : 11000000.codec
        Bus info      : platform:11000000.codec
        Driver version: 4.7.0

Driver Info (not using libv4l2):
        Driver name   : 11000000.codec
        Card type     : 11000000.codec
        Bus info      : platform:11000000.codec
        Driver version: 4.7.0

After this patch:

Driver Info (not using libv4l2):
        Driver name   : s5p-mfc
        Card type     : s5p-mfc-dec
        Bus info      : platform:11000000.codec
        Driver version: 4.7.0

Driver Info (not using libv4l2):
        Driver name   : s5p-mfc
        Card type     : s5p-mfc-enc
        Bus info      : platform:11000000.codec

4759bb4686 [media] s5p-mfc: set capablity bus_info as required by VIDIOC_QUERYCAP
The driver doesn't set the struct v4l2_capability bus_info field so the
v4l2-compliance tool reports the following errors for VIDIOC_QUERYCAP:

Required ioctls:
                VIDIOC_QUERYCAP returned 0 (Success)
                fail: v4l2-compliance.cpp(304): string empty

This patch fixes by setting the field in VIDIOC_QUERYCAP ioctl handler:

Required ioctls:
                VIDIOC_QUERYCAP returned 0 (Success)
        test VIDIOC_QUERYCAP: OK

6d2b749732 [media] s5p-mfc: use vb2_is_streaming() to check vb2 queue status
The streaming field in struct vb2_queue is meant to be private and should
not be used by drivers directly, instead the vb2_is_streaming() function
should be used to check the videobuf2 queue streaming status.

c8e913e19b [media] s5p-mfc: don't print errors on VIDIOC_REQBUFS unsupported mem type
The V4L2 documentation says that applications must call the VIDIOC_REQBUFS
ioctl to determine if a memory mapped, user pointer or DMABUF based I/O is
supported by the driver.

For example GStreamer does this by first calling VIDIOC_REQBUFS with count
zero for all the possible streaming I/O methods and then finally doing the
real VIDIOC_REQBUFS with count N using a known to be supported memory type.

But the driver prints an error on VIDIOC_REQBUFS if the memory type is not
supported which leads to the following errors that can confuse the users:

[  178.704390] vidioc_reqbufs:575: Only V4L2_MEMORY_MMAP is supported
[  178.704666] vidioc_reqbufs:575: Only V4L2_MEMORY_MMAP is supported

b16a2d872d [media] s5p-mfc: fix null pointer deference in clk_core_enable()
Fix null pointer deference in clk_core_enable() when driver unbind is run
when there is an application has an active pipeline playing.

s5p_mfc_release() gets called after s5p_mfc_final_pm() disables and does
clk_put() and s5p_mfc_release() attempts to enable clock and runs into
null pointer deference accessing invalid pointer.

The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding of in a range of formats.
The driver provides with VPU firmware download, memory management and
the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and
IOMMU address for vcodec hw device access. When a decode/encode instance
opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU
interface to interrupt vpu to handle decoding/encoding jobs.

fc845e520b [media] v4l: vsp1: Support runtime modification of controls
Controls are applied to the hardware in the configure operation of the
VSP entities, which is only called when starting the video stream. To
enable runtime modification of controls we need to call the configure
operations for every frame. Doing so is currently not safe, as most
parameters shouldn't be modified during streaming. Furthermore the
configure operation can sleep, preventing it from being called from the
frame completion interrupt handler for the next frame.

Fix this by adding an argument to the configure operation to tell
entities whether to perform a full configuration (as done now) or a
partial runtime configuration. In the latter case the operation will
only configure the subset of parameters related to runtime-configurable
controls, and won't be allowed to sleep when doing so.

Because partial reconfiguration can depend on parameters computed when
performing a full configuration, the core guarantees that the configure
operation will always be called with full and partial modes in that
order at stream start. Entities thus don't have to duplicate
configuration steps in the full and partial code paths.

This change affects the VSP driver core only, all entities return
immediately from the configure operation when called for a partial
runtime configuration. Entities will be modified one by one in further
commits.
