ARM: dts: Configure interconnect target module for am437x sgx
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 properly: # echo on > /sys/bus/platform/devices/5600fe00.target-module/power/control # rwmem 0x5600fe00 # revision register 0x5600fe00 = 0x40000000 # echo auto > /sys/bus/platform/devices/5600fe00.target-module/power/control # 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.
