SM7125 is the SoC found in the Xiaomi Redmi Note 9 Pro(joyeuse) cellphone.
This series adds support to bring up the CSIPHY, CSID, VFE/RDI interfaces.

Since SM7125 is a low-speed variant of SC7180, SC7180 testers please
take a look and have a test as well.

sc7180 provides

- 2 x VFE
- 1 x VFE Lite
- 2 x CSID
- 1 x CSID Lite
- 4 x CSI PHY

The sc7180-camss binding should be comaptible with sdm845 yaml.
I've copied a new yaml from sdm845-camss.yaml, strip all _src clk and
put new maintainer information. If this is not desirable then i can add binding to
existing sdm845 yaml instead.

In addition, a bootable tree of sm7125/joyeuse is availble at:

What changed exactly? That's too vague.

Could you please rebase your series with

https://lore.kernel.org/linux-arm-msm/20240522154659.510-1-quic_grosikop@quicinc.com/

taken in ?

I think your patchset ends up with less churn in it as a result.
