Kevin, I am testing Smartreflex on your Branch 'pm-wip/voltdm'. There seems an issue with reading VP registers. For OMAP3 and OMAP4 reading debugfs entries shows constant voltage. Logs are: OMAP3: # cat /debug/voltage/vdd_mpu_iva/curr_nominal_volt 1200000 # cat /debug/voltage/vdd_core/curr_nominal_volt 1200000 # echo 1 > /debug/voltage/vdd_mpu_iva/smartreflex/autocomp [ 311.680816] omap_device: smartreflex.0: new worst case activate latency 0: 91552 # echo 1 > /debug/voltage/vdd_core/smartreflex/autocomp # cat /debug/voltage/vdd_core/vp/curr_volt 900000 # cat /debug/voltage/vdd_mpu_iva/vp/curr_volt 900000 OMAP4: # cat /debug/voltage/vdd_core/curr_nominal_volt 1200000 # cat /debug/voltage/vdd_mpu/curr_nominal_volt 1375000 # cat /debug/voltage/vdd_iva/curr_nominal_volt 1188000 # # echo 1 > /debug/voltage/vdd_mpu/smartreflex/autocomp [ 61.514038] omap_device: smartreflex.2: new worst case activate latency 0: 30517 # echo 1 > /debug/voltage/vdd_core/smartreflex/autocomp # echo 1 > /debug/voltage/vdd_mpu/smartreflex/autocomp # # cat /debug/voltage/vdd_iva/curr_nominal_volt 1188000 # cat /debug/voltage/vdd_iva/vp/curr_volt 1200000 # # echo 1 > /debug/voltage/vdd_iva/smartreflex/autocomp # cat /debug/voltage/vdd_iva/vp/curr_volt 812500 # # cat /debug/voltage/vdd_mpu/vp/curr_volt 812500 # cat /debug/voltage/vdd_core/vp/curr_volt 812500 # This Issue is not reproduced on 'pm-core' branch, seems in the voltage Layer Clean up Patches somewhere some thing is goofed up.
