The other not so good option to make DSS PM work would be to add OCPIF_SWSUP_IDLE flag to our l3_main_2__dss_* slave interfaces(which have the hack "dss_fck" as slave clock). I gave this approach a try, that too isn't working so well. When I disable DSS, I get CM_DSS_DSS_CLKCTRL.IDLEST as 0x1, and CM_DSS_CLKSTCTRL.CLKACTIVITY_DSS_L3_ICLK is set. I wonder why that's happening.
I have seen DSS get stuck in transition, with just a clkdm state toggle (from say HWSUP to SWWKUP) while its optional clocks are not running. Thats probably whats happening now. Did you try keeping the modulemode enabled and see if it really gates DSS/system sleep. I remember testing with Teros CORE ret/off patches and I was always seeing DSS modulemode enabled but it wasn't gating sleep. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
