Subject: [PATCH 112/224] usb: mtu3: set otg_sel for u2port only if works as
|
|
dual-role mode
|
|
|
|
When set otg_sel(SSUSB_U2_PORT_OTG_SEL) for u2port which supports
|
|
dual-role mode, the controller will automatically switch mode
|
|
between host and device according to IDDIG signal. But if the
|
|
u2port only supports device mode, and no IDDIG pin is provided,
|
|
setting otg_sel may cause failure of detection by host.
|
|
So set it only for dual-role mode.
