Is it expected? Another observation is, if I include DSS driver into the kernel then I get proper count numbers for dss_pwrdm. (not tried same for usb though) 2) Missing clockdomain in usb clock - [root@arago /]# dmesg | grep -ir hwmod [ 0.114868] omap_hwmod: usbtll_fck: missing clockdomain for usbtll_fck. ... 3) Not sure how this can be handled, since from TWL regulator output perspective it is NA. I enabled DUMMY_REGILATOR option and tried it, it works.
