This patch adds the new EXTCON_CHG_USB_SDP connector to support SDP (Standard
Downstream Port) USB charging port. The commit 11eecf910bd8 ("extcon: Modify
the id and name of external connector") add the new EXTCON_CHG_USB_SDP
connector which support the both data transfer and usb charging at the same
time.

Why for MAX77693_CHARGER_TYPE_USB you are not setting the EXTCON_USB
type? From the description and max14577 code I would suspect that you
want to set both: USB and SDP.

I am missing something. If this is MAX8997_CHARGER_TYPE_USB but not
MAX8997_MUIC_ADC_OPEN then you will set only SDP, not USB. Aren't they
symmetric?
You aren't setting the SDP in ADC handler, only in charger handler. Why?
Best regards,
Krzysztof

You're right. It is my mistake. I'll fix it.
