Subject: [PATCH v4 0/6] media: qcom: camss: Add sc8280xp support

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

- b4 trailes --update -> + Konrad's Acks

V3:
- Strip pointer to dependencies from yaml patch
  I was hoping the robot would understand the links but it doesn't -
  Krzysztof

V2:
- Rebase to capture is_lite flag from named power-domain series
- Amends commit log of final patch to give more detail on rename - Konrad
- Opted not to change switch() statements with returns. - bod/Konrad

Requires CAMCC for sc8280xp which applies to qcom/clk-for-6.7:

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@...aro.org

Requires the named power-domain patches which apply to media-tree/* :
https://lore.kernel.org/linux-arm-msm/20231101-b4-camss-named-power-domains-v3-5-bbdf5f22462a@linaro.org/
b4 shazam 20231101-b4-camss-named-power-domains-v3-5-bbdf5f22462a@...aro.org

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
