How to check whether CDP/DCP is configured

[praneethreddy46]

Hi,

Platform : imx6solo/6Dualite based customized board

kernel: 3.10.17

my question is whether charging downstream port (CDP) and Dedicated charging port (DCP) is hardware  or software depenedency ? How can we check whether usb port is  CDP/DCP port ?

Please reply.

Regards,

i.MX6 has hardware USB charger detector block that detects whether the upstream-facing device is connected to a down-stream facing charger, either a dedicated USB charger or a host charger.

Please refer chapter 66.2.7 "Charger detection" of i.MX 6 Processor Reference Manual for the details.

Have a great day,
Victor
