    ARM: dts: dra7: Add l4 interconnect hierarchy and ti-sysc data · 549fce06

    Similar to commit 8f42cb7f ("ARM: dts: omap4: Add l4 interconnect
    hierarchy and ti-sysc data"), let's add proper interconnect hierarchy
    for l4 interconnect instances with the related ti-sysc interconnect
    module data as in Documentation/devicetree/bindings/bus/ti-sysc.txt.
    
    Using ti-sysc driver binding allows us to start dropping legacy platform
    data in arch/arm/mach-omap2/omap*hwmod*data.c files later on in favor of
    ti-sysc dts data.
    
    This data is generated based on platform data from a booted system
    and the interconnect acces protection registers for ranges. To avoid
    regressions, we initially validate the device tree provided data
    against the existing platform data on boot.
    
    Note that we cannot yet include this file from the SoC dtsi file until
    the child devices are moved to their proper locations in the
    interconnect hierarchy in the following patch. Otherwise we would have
    the each module probed twice.
