    pca954x: harmonize pca9547 and pca954x and add pca9540 support · 97dbd377
    Bjoern A. Zeeb authored
    The two implementations for the pca9548 switch and the pca9547 mux
    seemed close enough so we can put them together and with a bit more
    abstraction add pca9540 support.
    While here apply a bit of consistency in variable and driver naming and
    use device_has_property instead of the FDT-only OF_ variant.
    This disconnects pca9547 from the build but does not yet delete it.
