   4 Subject: [PATCH 44/52] Fix Max3353 otg toggle bug
   5
   6 The max3353 charge pump work with SOC FS/LS transceiver,
   7 during dual role toggle, the root hub port should be powered
   8 off to disable port status detection when suspend host mode,
   9 otherwise it won't work properly when switch to host mode.
