| 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. |
