Yes:
# cat /debug/pm_debug/count |grep dss
[ 35.356567] pwrdm state mismatch(l3init_pwrdm) 3 != 1
[ 35.361938] pwrdm state mismatch(cam_pwrdm) 3 != 0
[ 35.366973] pwrdm state mismatch(ivahd_pwrdm) 3 != 1
[ 35.372253] pwrdm state mismatch(tesla_pwrdm) 3 != 1
[ 35.377532] pwrdm state mismatch(abe_pwrdm) 3 != 1
dss_pwrdm (RET),OFF:1,RET:11,INA:0,ON:11,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0
l3_dss_clkdm->dss_pwrdm (0)
then I load and unload the dss modules, and then:
# cat /debug/pm_debug/count |grep dss
[ 60.813629] pwrdm state mismatch(l3init_pwrdm) 3 != 1
[ 60.819000] pwrdm state mismatch(cam_pwrdm) 3 != 0
[ 60.824127] pwrdm state mismatch(ivahd_pwrdm) 3 != 1
[ 60.829376] pwrdm state mismatch(tesla_pwrdm) 3 != 1
[ 60.834625] pwrdm state mismatch(abe_pwrdm) 3 != 1
dss_pwrdm (ON),OFF:1,RET:21,INA:0,ON:22,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0
l3_dss_clkdm->dss_pwrdm (0)
