Hi all, For a while we've been idling sgx module on omap4 by probing it with ti-sysc interconnect target module driver. This allows leaving out any platform data in favor of device tree data, and idles the module for PM even if we don't have any sgx driver. I've added similar configuration for omap34xx, omap36xx, omap5 and am335x. Adding dra7 should work too, but my beagle x15 is suffering from a power supply problem right now and I'll need to work more on that later on. For am335x, the recently posted prm rstctrl driver is needed. The other SoCs here don't have a dependency to the prm rstctrl driver. And probably am335x child driver(s) also need to map the rstctrl register to increase the deassert use count. Please review and test, this should allow sgx child driver(s) to just use PM runtime to enable the module with no platform data. I've only tested these SoCs via sysfs to ensure the sgx module gets enabled and disabled properly. If you know something about sgx, please describe more why the sgx registers seem to be at different place for each SoC like between omap34xx and omap36xx. These patches may have some dependencies to what I've queued into my for-next branch for fixes so it's best to test with that merged in. Linux next should be usable for testing with these the next time it gets integrated.
