ARM: dts: Configure interconnect target module for omap3 sgx
Looks like omap34xx OCP registers are not readable unlike on omap36xx. We use SGX revision register instead of the OCP revision register for 34xx and do not configure any SYSCONFIG register unlike for 36xx. I've tested that the interconnect target module enables and idles just fine with PM runtime control via sys: # echo on > $(find /sys -name control | grep \/5000); rwmem 0x5000fe10 # rwmem 0x50000014 # SGX revision register on 36xx 0x50000014 = 0x00010205 # echo auto > $(find /sys -name control | grep \/5000) # rwmem 0x5000fe00 And when idled, it will produce "Bus error" as expected.
