Subject: [PATCH v2 0/4] USB-C TCPM Orientation Support

Hi,

this adds the support to controll the optional connector-orientation
available on some TCPC from the TCPM.

I used an custom board with OnSemi FUSB307B TCPC which is spec [1]
compatible but albeit the spec [1] says that this pin is controlled by
the TCPC if 'TCPC_CONTROL.DebugAccessoryControl = 0' it isn't at least
for this device.

I'm unsure if the usb tcpci spec has an copy'n'paste failure since
'TCPC_CONTROL.DebugAccessoryControl' shouldn't control the state of the
'connector orientation' pin or if the OnSemi FUSB307B has an HW bug.
Since on my device the 'TCPC_CONTROL.DebugAccessoryControl' is set to
0 but the register wasn't updated automatically.

Regards,
  Marco
