    ARM: dts: Configure interconnect target module for am437x sgx · a5ebccc8
    Tony Lindgren authored
    This seems to be similar to what we have for am335x. The following can be
    tested via sysfs with the to ensure the SGX module gets enabled and disabled
    # echo on > /sys/bus/platform/devices/
    # rwmem 0x5600fe00              # revision register
    0x5600fe00 = 0x40000000
    # echo auto > /sys/bus/platform/devices/
    # rwmem 0x5000fe00
    Bus error
    Note that this patch depends on the PRM rstctrl driver that has
    been recently posted. If the child device driver(s) need to prevent
    rstctrl reset on PM runtime suspend, the drivers need to increase
    the usecount for the shared rstctrl reset that can be mapped also
    for the child device(s) or accessed via dev->parent.
