    Subject[PATCH v15 1/4] dt-bindings: i2c: pca954x: Correct interrupt support
    Date
    Only some of the PCA954x compatible ICs have interrupt
    capability, but the binding advertises it on all ICs.

    Sync the dt-binding with the driver and only advertise it on:
    - nxp,pca9542
    - nxp,pca9543
    - nxp,pca9544
    - nxp,pca9545
