Perhaps we should restructure it to match hw revision? Especially since one can get it from the hardware itself.. Konrad

"The PHY can do it" but I'd be surprised to find there's a single real implementation of it outside of a silicon test bench. --- bod

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.

Run Firefox 2. Update about:config to enable pipewire 3.
