Proprietary chargers pull D+/- to specific voltages between 2.0-3.3V (VLGC) for identification. The DM voltage may not exceed VLGC due to pull-down resistor. Hence a proprietary charger is detected as a Standard downstream port (SDP). Read line state to distinguish between SDP and proprietary charger. The DP voltage would exceed VLGC for proprietary chargers. D- can be greater than VLGC when a low speed device is attached via Accessory charger adapter (ACA-A). Hence mark the charger as ACA-A if ID resistance is RID_A and D- > VLGC CRs-Fixed: 368688 Change-Id: I3497efbe025abf150078a19d69254f75f5df5b2a Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org>
