Subject: [PATCH 43/51] phy: rockchip-inno-usb2: Sync initial otg state
|
|
|
|
The initial otg state for the phy defaults to device mode. The actual
|
|
state isn't detected until an ID IRQ fires. Fix this by syncing the ID
|
|
state during initialization.
|
|
|
|
Fixes: 51a9b2c03dd3 ("phy: rockchip-inno-usb2: Handle ID IRQ")
