According to Type-C specification 4.8.2 Non-USB Charging Methods, proprietary charging methods shall only define the current level and shall not change the voltage delivered on VBUS. So I think that Type-C specification prohibits Quick Charge 9V/12V using a Type-C cable. I would like to confirm whether TPS65982 will support QC 9V/12V or not.
If it won't support QC 9V/12V, I need to say so to my customer.
