    ARM: dts: Configure interconnect target module for omap4 dss · 63b34416
    Tony Lindgren authored
    We can now probe devices with device tree only configuration using
    ti-sysc interconnect target module driver. Let's configure the
    module, but keep the legacy "ti,hwmods" peroperty until the child
    devices are probing with ti-sysc interconnect driver.
    
    The display subsystem (DSS) is in a 16MB interconnect target module
    mapped to l4 and l3 buses. We are only using the l3 port as recommended
    by the TRM. So there is no need to configure l4 ranges like we've done
    for l4 ABE instance for example.
    
    Initially let's just update the top level dss node to probe with ti-sysc
    interconnect target module driver. The child nodes are still children
    of dispc, only the node indentation changes for them now along with
    using the reg range provided by top level dss.
    
    Let's also add add a note about using only the l3 access without l4
    as noted in the TRM.
