The register abstraction has wrappers around both the normal writel()
and its writel_relaxed() counterpart, but this has led to a lot of users
ending up with the relaxed version.
There is sometimes a need to intentionally pick the relaxed accessor for
performance critical functions, but I noticed that each hantro_reg_write()
call also contains a non-relaxed readl(), which is typically much more
expensive than a writel, so there is little benefit here but an added
risk of missing a serialization against DMA.
To make this behave like other interfaces, use the normal accessor by
default and only provide the relaxed version as an alternative for
performance critical code. hantro_postproc.c is the only place that
used both the relaxed and normal writel, but this does not seem
cricital either, so change it all to the normal ones.

In some configurations, gcc decides not to inline the register accessor
functions, which in turn leads to lots of temporary hantro_reg structures
on the stack that cannot be eliminated because they escape into an
uninlined function:
drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:1022:1: warning: the frame size of 1112 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Mark all of these as __always_inline so the compiler is able to completely
eliminate the temporary structures instead, which brings the stack usage
back down to just the normal local variables.

The mtk8195_jpegenc_drvdata object was added outside of an #ifdef causing
a harmless build warning.
drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable]
1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = {
| ^~~~~~~~~~~~~~~~~~~~~~~
A follow-up patch moved it inside of an #ifdef, which caused more
warnings, and a third patch ended up adding even more #ifdefs. These
were all bogus, since the actual problem here is the incorrect use
of of_ptr(). Since the driver (like any other modern platform driver)
only works in combination with CONFIG_OF, there is no point in hiding
the reference, so just remove that along with all the pointless #ifdef
checks in the driver.
This improves build coverage and avoids running into the same problem
again when another part of the driver gets changed that relies on
the #ifdef blocks to be completely matched.

Address these compiler warnings by initialising the m_best and p_best

The warnings may well be a false positive but it is difficult for a

What happens is that cmd_cnt tracks the amount of firmware data packets

Switch to use the firmware count, as the message is all about reporting

The tc358746 driver selects CONFIG_GENERIC_PHY_MIPI_DPHY and links to
that, but this fails when CONFIG_GENERIC_PHY is disabled, because Kbuild
then never enters the drivers/phy directory for building object files:
ERROR: modpost: "phy_mipi_dphy_get_default_config_for_hsclk" [drivers/media/i2c/tc358746.ko] undefined!
Add an explicit 'select GENERIC_PHY' here to ensure that the directory
is entered, and add another dependency on that symbol so make it
more obvious what is going on if another driver has the same problem,
as this will produce a Kconfig warning.

For historical reasons, unbound workqueues with max concurrency limit of 1
are considered ordered, even though the concurrency limit hasn't been
system-wide for a long time. This creates ambiguity around whether ordered
execution is actually required for correctness, which was actually confusing
for e.g. btrfs (btrfs updates are being routed through the btrfs tree).
There aren't that many users in the tree which use the combination and there
are pending improvements to unbound workqueue affinity handling which will
make inadvertent use of ordered workqueue a bigger loss. This pull request
clarifies the situation for most of them by updating the ones which require
ordered execution to use alloc_ordered_workqueue().
There are some conversions being routed through subsystem-specific trees and
likely a few stragglers. Once they're all converted, workqueue can trigger a
warning on unbound + @max_active==1 usages and eventually drop the implicit
ordered behavior.

AV1 film grain feature requires to use the postprocessor to produce
valid frames. In such case the driver shouldn't propose native pixels
format but only post-processed pixels format.
Additionally if when setting a control a value could change capture
queue pixels formats it is needed to call hantro_reset_raw_fmt().

Film grain feature add "old style" grain noise on decoded streams.
Grain noise is applied after decoding by the postprocessor.
The level of grain is based on gaussian sequence.

AV1 hardware decoder needs entropy parameters to decode frames.
They are computed from various arrays defined in AV1 section
"9.4. Default CDF tables".
Add helpers functions to init, store and get these parameters.

Fraction bytes-per-pixel exist for some packed format. You will find
notably on Rockhip platform that 10bit data is stored fully packed,
meaning that there is 1.25 pixels per bytes. This can be represented
with the fraction 5/4 and can be used to scale the width into a
bytesperline.

Since start_streaming is only called if there are at least two
buffers queued, the ceudev->capture list will never be empty, so
the check whether there are no buffers can be dropped.
Note that the '!buf' check was wrong in any case, if we wanted to
check for an empty list it should have used list_empty().
