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