Dear all,

 

Would you teach about USB_OTG_PWR_CTL_WAKE and USB_OTG_ID in i.MX6 Linux BSP?

 

For USB_OTG_ID
In MX6DL-SABRE-SDP, USB_OTG_ID are connected as follows.
USB_OTG_ID => ENET_RX_ER(W23)

 

So, I understand Hardware processes this signal.
(ALT0 mode of ENET_RX_ER is used)

 

Is my understanding right?


For USB_OTG_PWR_CTL_WAKE
I was not able to find this signal with a schematic of the SABRE.
USB_OTG_PWR_CTL_WAKE is multiplexed by GPIO_8.
However, GPIO_8 is used as DISP0_SER_RS.

 

What kind of case is USB_OTG_PWR_CTL_WAKE used in?

Does Linux BSP support USB_OTG_PWR_CTL_WAKE?

 

Best Regards,
Yuuki
