    bus: ti-sysc: Implement SoC revision handling · feaa8bae
    Tony Lindgren authored
    We need to know SoC type and features for cases where the same SoC
    may be installed in various versions on the same board and would need
    a separate dts file otherwise for the different variants.
    
    For example, am3703 is pin compatible with omap3630, but has sgx and
    iva accelerators disabled. We must not try to access the sgx or iva
    module registers on am3703, and need to set the unavailable devices
    disabled early.
    
    Let's also detect omap3430 as that is needed for display subsystem
    (DSS) reset later on, and GP vs EMU or HS devices. Further SoC
    specific disabled device detection can be added as needed, such as
    dra71x vs dra76x rtc and usb4.
