Pull irq cleanups from Thomas Gleixner:
"A series of treewide cleanups to ensure interrupt request consistency.
- Add the missing IRQF_COND_ONESHOT flag to devm_request_irq()
This is inconsistent vs request_irq() and causes the same issues
which where addressed with the introduction of this flag
- Cleanup IRQF_ONESHOT and IRQF_NO_THREAD usage
Quite some drivers have inconsistent interrupt request flags
related to interrupt threading namely IRQF_ONESHOT and
IRQF_NO_THREAD. This leads to warnings and/or malfunction when
forced interrupt threading is enabled.
- Remove stub primary (hard interrupt) handlers
A bunch of drivers implement a stub primary (hard interrupt)
handler which just returns IRQ_WAKE_THREAD. The same functionality
is provided by the core code when the primary handler argument of
request_thread_irq() is set to NULL"

The uvc_alloc_urb_buffer() function implicitly depended on the
stream->urb_size field, which was set by its caller,
uvc_alloc_urb_buffers(). This implicit data flow makes the code harder
to follow.
More importantly, stream->urb_size was updated within the allocation
loop before the allocation was confirmed to be successful. If the
allocation failed, the stream object would be left with a urb_size that
doesn't correspond to valid, allocated URB buffers.
Refactor uvc_alloc_urb_buffer() to accept the buffer size as an explicit
argument. This makes the function's dependencies clear and improves the
robustness of the error handling path. The stream->urb_size is now set only
after a complete and successful allocation.
This is a pure refactoring and introduces no functional changes.

If a frame has size of less or equal than one packet size
uvc_alloc_urb_buffers() is unable to allocate memory for it due to a
off-by-one error.
Fix the off-by-one-error and now that we are at it, make sure that
stream->urb_size has always a valid value when we return from the
function, even when an error happens.

Some devices, such as the Grandstream GUV3100 and the LSK Meeting Eye
for Business & Home, exhibit entity ID collisions between units and
streaming output terminals.
The UVC specification requires unit and terminal IDs to be unique, and
uses the ID to reference entities:
- In control requests, to identify the target entity
- In the UVC units and terminals descriptors' bSourceID field, to
identify source entities
- In the UVC input header descriptor's bTerminalLink, to identify the
terminal associated with a streaming interface
Entity ID collisions break accessing controls and make the graph
description in the UVC descriptors ambiguous. However, collisions where
one of the entities is a streaming output terminal and the other entity
is not a streaming terminal are less severe. Streaming output terminals
have no controls, and, as they are the final entity in pipelines, they
are never referenced in descriptors as source entities. They are
referenced by ID only from innput header descriptors, which by
definition only reference streaming terminals.
For these reasons, we can work around the collision by giving streaming
output terminals their own ID namespace. Do so by setting bit
UVC_TERM_OUTPUT (15) in the uvc_entity.id field, which is normally never
set as the ID is a 8-bit value.
This ID change doesn't affect the entity name in the media controller
graph as the name isn't constructed from the ID, so there should not be
any impact on the uAPI.
Although this change handles some ID collisions automagically, keep
printing an error in uvc_alloc_new_entity() when a camera has invalid
descriptors. Hopefully this message will help vendors fix their invalid
descriptors.
This new method of handling ID collisions includes a revert of commit
758dbc756aad ("media: uvcvideo: Use heuristic to find stream entity")
that attempted to fix the problem urgently due to regression reports.

Similarly to what is done in Hantro, avoid exposing equal video codecs to
userspace. Equal video codecs allow scheduling work between the cores.
For that kernel support is required, which does not yet exist.
Until that is implemented, avoid exposing each core separately to
userspace so that multicore can be added in the future without breaking
userspace ABI.
This currently applies only to RK3588 which has 2 equal VDPU381 decoders,
but will be applied for all SoC supported by rkvdec that has multiple DTS
nodes with the same compatible.

The RCB (Rows and Cols Buffers) are a set of buffers used by other
variations of the decoder to store temporary data.
Those variation come with a dedicated SRAM area used to store those
buffers for better performances.
The buffer sizes are either the width or height of the frame being
decoded multiplied by a documented factor and can be stored either
in SRAM or RAM.
A fallback to RAM is provided if the SRAM is full (e.g.: multiple
streams are being decoded at the same time).
To manage the different kind of allocation, an enum is added to the
rkvdec_aux_buf struct to specify how the buffer was allocated, and
so, how to free it.
This commit is in preparation of other variants support.

In an effort to merge the rkvdec2 driver [1] with this one, switch from
writel() calls to using structs to represent the register mappings.
This is done in order to have all supported decoders use the same format
in the future and ease reading of the code.
Using structs also improves stability as the hardware is tested and
validated downstream using a similar method.
It was noticed, on decoders, that:
- Some registers require to be writen in increasing order [2]
- Some registers, even if unrelated, need to be written to their reset
values (it was the case here for axi_ddr_[rw]data).
Using structs can also help improving performance later when, e.g.
multicore support is added on RK3588.
Performance seems to be slightly improved, but at least, not made worse.
Running fluster's JVT-AVC_V1 test suite with GStreamer on the Radxa ROCK
PI 4 SE gives the following times:
Before this patch:
- --jobs 1: Ran 129/135 tests successfully in 77.167 secs
- --jobs 6: Ran 129/135 tests successfully in 23.046 secs
With this patch:
- --jobs 1: Ran 129/135 tests successfully in 70.698 secs
- --jobs 6: Ran 129/135 tests successfully in 22.917 secs
This also shows that the fluster score hasn't changed.

The vdpu381 decoder found on newer Rockchip SoC need the information
from the long term and short term ref pic sets from the SPS.
So far, it wasn't included in the v4l2 API, so add it with new dynamic
sized controls.
Each element of the hevc_ext_sps_lt_rps array contains the long term ref
pic set at that index.
Each element of the hevc_ext_sps_st_rps contains the short term ref pic
set at that index, as the raw data.
It is the role of the drivers to calculate the reference sets values.

The Synopsys DesignWare MIPI CSI-2 Receiver is a CSI-2 bridge with
one input port and one output port. It receives the data with the
help of an external MIPI PHY (C-PHY or D-PHY) and passes it to e.g.,
the Rockchip Video Capture (VICAP) block on recent Rockchip SoCs.
Add a V4L2 subdevice driver for this unit.

The rkisp1_flt_config() function performs an initial direct write to
RKISP1_CIF_ISP_FILT_MODE without including the RKISP1_CIF_ISP_FLT_ENA
bit, which clears the filter enable bit in the hardware.
The subsequent read/modify/write sequence then reads back the register
with the enable bit already cleared and cannot restore it, resulting in
the filter being inadvertently disabled.
Remove the redundant direct write. The read/modify/write sequence alone
correctly preserves the existing enable bit state while updating the
DNR mode and filter configuration bits.

Printing error messages on pm_runtime_put() returning negative values
is not particularly useful.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.
Accordingly, update rkisp1_vb2_stop_streaming() to simply discard the
return value of pm_runtime_put().
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of
hex.h interfaces to directly #include <linux/hex.h> as part of the process
of putting kernel.h on a diet.
Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.
This change has been build-tested with allmodconfig on most ARCHes. Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

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.

During normal playback, stream-on for input is followed by output, and
only after input stream-on does actual streaming begin. However, when
gst-play performs a seek, both input and output streams are stopped,
and on restart, output stream-on occurs first. At this point, firmware
has not yet started streaming. Queuing output buffers before the firmware
begins streaming causes it to process buffers in an invalid state, leading
to an error response. These buffers are returned to the driver as errors,
forcing the driver into an error state and stopping playback.
Fix this by deferring output buffer queuing until stream-on completes.
Input buffers can still be queued before stream-on as required.
