It is reported that commit 95f408bbc4e4 ("media: cx23885: Ryzen DMA
related RiSC engine stall fixes") caused regresssions with other CPUs.
Ensure that the quirk will be applied only for the CPUs that
are known to cause problems.
A module option is added for explicit control of the behaviour.

Doing a survey of the kernel tree, this appears to be expected because
'#include <asm/irq.h>' is always after the linux includes.
This also fixes warnings of this variety (with Clang):

There is a smatch warning:
drivers/media/dvb-frontends/drxk_hard.c: drivers/media/dvb-frontends/drxk_hard.c:1478 scu_command() error: we previously assumed 'parameter' could be null (see line 1467)
Telling that parameter might be NULL. Well, it can't, due to the
way the driver works, but it doesn't hurt to add a check, in order
to shut up smatch.

The Video Engine (VE) embedded in the Aspeed AST2400 and AST2500 SOCs
can capture and compress video data from digital or analog sources. With
the Aspeed chip acting a service processor, the Video Engine can capture
the host processor graphics output.
Add a V4L2 driver to capture video data and compress it to JPEG images.
Make the video frames available through the V4L2 streaming interface.

Currently v4l2_device_register_subdev_nodes() does not initialize the
dev_parent field of the video_device structs it creates for subdevices
being registered. This leads to __video_register_device() falling back
to the parent device of associated v4l2_device struct, which often does
not match the physical device the subdevice is registered for.
Due to the problem above, the links between real devices and v4l-subdev
nodes cannot be obtained from sysfs, which might be confusing for the
userspace trying to identify the hardware.
Fix this by initializing the dev_parent field of the video_device struct
with the value of dev field of the v4l2_subdev struct. In case of
subdevices without a parent struct device, the field will be NULL and the
old behavior will be preserved by the semantics of
__video_register_device().

A common mistake is to assume that initializing a var with:
struct foo f = { 0 };
Would initialize a zeroed struct. Actually, what this does is
to initialize the first element of the struct to zero.
According to C99 Standard 6.7.8.21:
"If there are fewer initializers in a brace-enclosed
list than there are elements or members of an aggregate,
or fewer characters in a string literal used to initialize
an array of known size than there are elements in the array,
the remainder of the aggregate shall be initialized implicitly
the same as objects that have static storage duration."
So, in practice, it could zero the entire struct, but, if the
first element is not an integer, it will produce warnings:
drivers/staging/media/sunxi/cedrus/cedrus.c:drivers/staging/media/sunxi/cedrus/cedrus.c:78:49: warning: Using plain integer as NULL pointer
drivers/staging/media/sunxi/cedrus/cedrus_dec.c:drivers/staging/media/sunxi/cedrus/cedrus_dec.c:29:35: warning: Using plain integer as NULL pointer
As the right initialization would be, instead:
struct foo f = { NULL };
Another way to initialize it with gcc is to use:
struct foo f = {};
That seems to be a gcc extension, but clang also does the right thing,
and that's a clean way for doing it.
Anyway, I decided to check upstream what's the most commonly pattern.
The "= {}" pattern has about 2000 entries:
$ git grep -E "=\s*\{\s*\}"|wc -l
1951
The standard-C compliant pattern has about 2500 entries:
$ git grep -E "=\s*\{\s*NULL\s*\}"|wc -l
137
$ git grep -E "=\s*\{\s*0\s*\}"|wc -l
2323
Meaning that developers have split options on that.
So, let's opt to the simpler form.

runtime PM by changing the operating mode.
The instruction for changing sleep mode to normal mode is from the

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based
system which this is.

We initially introduced a spin lock to ensure that the VPU registers
are not accessed concurrently between our setup function and IRQ
handler. The V4L2 M2M API ensures that only one decoding job runs at a
time, so the interrupt signaling the end of decoding will not occur
while the next picture is being configured.
Spurious interrupts are taken care of in the handler, by checking that
we have a valid M2M context and a decoding status available before
marking the buffers as done.
In addition, holding a spin lock could be problematic if non-atomic
operations are required in the setup process for future codec support.
As a result, remove the global IRQ spin lock.

The clock rate, while hardcoded until now, is actually a function of the
resolution, framerate and bytes per pixel. Now that we have an algorithm to
adjust our clock rate, we can select it dynamically when we change the
mode.
This changes a bit the clock rate being used, with the following effect:
+------+------+------+------+-----+-----------------+----------------+-----------+
| Hact | Vact | Htot | Vtot | FPS | Hardcoded clock | Computed clock | Deviation |
+------+------+------+------+-----+-----------------+----------------+-----------+

Only the 640x480, 1024x768 and 2592x1944 modes are significantly affected
by the new formula.
In this case, 640x480 and 1024x768 are actually fixed by this change.
Indeed, the sensor was sending data at, for example, 27.33fps instead of
30fps. This is -9%, which is roughly what we're seeing in the array.
Testing these modes with the new clock setup actually fix that error, and
data are now sent at around 30fps.
2592x1944, on the other hand, is probably due to the fact that this mode
can only be used using MIPI-CSI2, in a two lane mode, and never really
tested with a DVP bus.

The MIPI divider is also cleared as part of the clock setup sequence, so we
can remove that code.

The OV5640_SCLK2X_ROOT_DIVIDER_DEFAULT and OV5640_SCLK_ROOT_DIVIDER_DEFAULT
defines represent exactly the same setup, and are at the same value, than
the more consistent with the rest of the driver OV5640_SCLK2X_ROOT_DIV and
OV5640_SCLK_ROOT_DIV.
Remove them.

Part of the hardcoded initialization sequence is to set up the proper clock
dividers. However, this is now done dynamically through proper code and as
such, the static one is now redundant.
Let's remove it.
