2018-08-24MLK-16776 staging: typec: tcpci: use vbus from partner for EXTCON_USBLi Jun
Change to use the vbus from partner to notify EXTCON_USB. This is to work around the case of source only typec port connecting to Host PC via a Rp fixed cable. Acked-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Li Jun <jun.li@nxp.com>

Some usb device driver can't know the connect and disconnect to host if the vbus is always on, if use typec we can rely on cc line status to know that, so add a notification to let controller driver know device attach and detach from host.

[ Upstream commit 95a2562590c2f64a0398183f978d5cf3db6d0284 ] On some platforms there's an ITS available but it's not enabled because reading or writing the registers is denied by the firmware. In fact, reading or writing them will cause the system to reset. We could remove the node from DT in such a case, but it's better to skip nodes that are marked as "disabled" in DT so that we can describe the hardware that exists and use the status property to indicate how the firmware has configured things.
