In the AMD existing S0ix system seems needn't monitor SFH idle state, meanwhile SFH is powered by S5 rail and the rail keeps ON when SOC is in S3/S0i3 state. Regards to SFH stop working after S3 resume maybe caused by power rail and device context tear down during S3 suspend. In addition, we also need implement SFH suspend callback in amd-sfh-hid like as other vendor.
Thanks,
