vfe-170 and vfe-175 can be supported in the same file with some minimal
indirection to differentiate between the silicon versions.

sdm845 uses vfe-170, sc8280xp uses vfe-175-200. Lets rename the file to
capture its wider scope than vfe-170 only.

Add a PHY configuration sequence for the sc8280xp which uses a Qualcomm
Gen 2 version 1.1 CSI-2 PHY.

The PHY can be configured as two phase or three phase in C-PHY or D-PHY
mode. This configuration supports two-phase D-PHY mode.

V6:
- Add of camss.yaml passes on linux-stable/master as at
  commit: ff93872a ("clk: qcom: camcc-sc8280xp: Add sc8280xp CAMCC")

- Fixed IFE/VFE comment discongruity - Konrad

- Per my explaination I don't propose to change IFE/VFE naming since
  they are the same thing.

  SFE blocks should be named SFE though, not IFE/VFE

- Referring to Konrad's other comments on IFE/VFE naming
  https://lore.kernel.org/all/9a13471b-fc39-4081-8905-9d0d7c28b501@linaro.org/#t

  The next two changes I intend not covered in this SoC series

  a) Completing the conversion to named power-domains
  b) Camera NOC => OPPs for the camera NoC

  Not covered in this series though.

V5:
- Fixes the lower case 0x0c to 0x0C not sure how Konrad even saw this.
- Drops frequency table to just individual frequencies not full array of
  opps - Konrad

- As explained doesn't change the finding of frequencies.
  Current array size will ensure testing if (freq[x]) succeeds though I
  do agree this should be changed up.

  Plan to restructure struct params for specificity to VFE, CSID and will
  incorporate this change then.
  Link: https://lore.kernel.org/all/e80d4026-a525-48ef-b53a-f1276dd316e6@linaro.org

-  Reset sequence

   Right now the reset works. I agree qcom's downstream has more stuff in
   it. I've logged a task to evaluate expansion of the reset and to test
   across multiple platforms.

   For now not required for this drop.

- _src clocks

  One assumes the reason at some stage in time we didn't have SET_PARENT in
  our CAMCC which meant setting _src clocks was necessary. In any case it
  ought not to be necessary now.

  Removing the _src from existing platforms should be trivial however we
  might find that as a result some of the CAMCC drivers need to be updated.

  That obviously is a separate series.

V4:
- Drops all _src clocks and _SRC indexes in series.
  True enough the CAMCC driver has all of the appropriate SET_PARENT flags
  so there's no need to represent _src clocks. - Konrad

- I've opted not to split C-PHY and D-PHY init sequences up unless/until
  we have a C-PHY init sequence upstream. - bod/Konrad

V1:
sc8280xp is the SoC found in the Lenovo X13s. This series adds support to
bring up the CSIPHY, CSID, VFE/RDI interfaces.

A number of precursor patches make this series smaller overall than
previous series.

sc8280xp provides

- 4 x VFE, 4 RDI per VFE
- 4 x VFE Lite, 4 RDI per VFE
- 4 x CSID
- 4 x CSID Lite
- 4 x CSI PHY

I've taken the yaml from a dtsi series and included it here since 1) I sent
the yaml to the wrong person and 2) it already has RB from Krzysztof.

Requires CAMCC for sc8280xp which applies to qcom/clk-for-6.7:
https://lore.kernel.org/linux-arm-msm/20231026105345.3376-1-bryan.odonoghue@linaro.org/
b4 shazam 20231026105345.3376-1-bryan.odonoghue@linaro.org

Requires the named power-domain patches which apply to media-tree/* :

To use the camera on x13s with say Google Hangouts or Microsoft Teams you
will need to

1. Run Firefox
2. Update about:config to enable pipewire
3. Use this WIP version of libcamera
   https://gitlab.freedesktop.org/camera/libcamera-softisp
