V2:
- Adds Tested-by Julian Grahsl as indicated.
- Fixes low-level noise checkpatch --strict
I ended up having to push defines into static inlines for this.
- Adds Reviewed-by Robert Foss.
- Adds VFE/CSID fix for sdm845 as explicit additional sdm845 specific
patch per Robert's suggestion.
I took the time then to test out on sdm845 to ensure the new patch breaks
nothing "./cam -c 1 --capture=1 --file=capture.raw" continues to produce
expected data.

V1/RESEND:

This series is imported from excellent enabling work contributed by
Jonathan Marek which we have picked up in Linaro for the RB5 project.

The RB5 has a slightly different sku I think to Jonathan's platform -
QRB5165 in our case with a different version of LK the relevant bootloader
for the board.
As a result we needed to make some additional updates to the provided
patcheset, included here.
The most notable changes are:
- Addition of clocks.
- Addition of bandwidth settings.
- Representing the dependency on a VFE for a given CSID so that V4L
subdevs will come out of reset right when poked.
A full tree which is bootable and capable of producing pixel data from the
imx577 main sensor is availble here, with this series being a sub-set of
the necessary patches on the SoC side only.

csid_isr() only checks for the reset irq, so enabling any other irqs
doesn't make sense. The "RDI irq" comment is also wrong, the register
should be CSID_CSI2_RDIN_IRQ_MASK. Without this fix there may be an
excessive amount of irqs.

This is a leftover from my original patches, it doesn't serve any purpose.
(it was a reminder to figure out how downstream sets a particular field in
the register).

This function waits for halt_complete but doesn't do anything to cause
it to complete, and always hits the "VFE halt timeout" error. Just delete
this code for now.

From: Jonathan Marek <jonathan@marek.ca>
Add support for VFE found on SM8250 (Titan 480). This implementation is
based on the titan 170 implementation. It supports the normal and lite VFE,
and only supports the RDI0 capture path.
[bod: Updates hw_version callback]
[bod: Use static inline for macros reusing parameters checkpatch --strict]

From: Jonathan Marek <jonathan@marek.ca>
The Titan 480 camss found on SM8250 has 6 CSIPHY and 4 VFE/CSID.
CSID is compatible with the Titan 170 CSID, but the Titan 480 CSID are
inside the VFE region (between the "top" and "bus" registers), so a
workaround is added to avoid ioremap failure.
[bod] Fixed setting camnoc_axi_clk_src instead of camcc_camnoc_axi_clk
[jgrahsl, bod] Add slow_ahb_src clock values
[jgrahsl, bod] Add cpa_ahb clock values

Downstream makes some pretty explicit comments about voting for bus
bandwidth prior to camcc_camnoc_axi_clk_src. Working with camx downstream
also shows that the bandwidth vote is required to get that root clock
working.
Add a simple mechanism to declare set and unset named NOCs. Whereas the
objective is to enable the sm8250 specifically the code has been
implemented to allow setting of whatever NOCs different SoCs using this
driver may require.

The sm8250 CAMSS CSID depends on the VFE it is attached to being powered on
and clocked prior to taking the CSID out of reset.
It is possible to open just the CSID subdev from libcamera and attempt to
bring the CSID block up.
If we do not first bring up the VFE the CSID will fail to come out of
reset.

Similar to the SM8250 the CSID relies on the VFE to be clocked prior to
taking the CSID out of reset.
Apply the same fixup to SDM845 as SM8250.

Hi Bryan,
This patch needs to be CC-ed to devicetree@vger.kernel.org. I need an Acked-by from
the device tree maintainers before I can merge this series.
Everything else looks good, it's the only thing preventing this from merging.
Regards,
Hans
