[PATCH 1/3] extcon: Add documentation for EXTCON_CHG_USB_* and EXTCON_USB_*

[PATCH 1/3] extcon: Add documentation for EXTCON_CHG_USB_* and EXTCON_USB_*

[Baolin Wang]

Current there is both "EXTCON_USB" and "EXTCON_CHG_USB_SDP" which
both seem to suggest a standard downstream port. But there is no
documentation describing how these relate.

Thus add documentation to describe EXTCON_CHG_USB_SDP should always
appear together with EXTCON_USB, and EXTCON_CHG_USB_ACA would normally
appear with EXTCON_USB_HOST.

Looks good to me. But I prefer to use the 'extcon_set_state_sync' intead of extcon_set_cable_state_().

I sent the patches[1] for extcon API to alter the deprecated API.
If you possible, I'd like you to alter the extcon API instead of deprecated API.

Looks good to me.
But, you use the different word for ACA as following:
I think that 'would normally' is proper in descritpion.

- commit msg : EXTCON_CHG_USB_ACA would normally appear with EXTCON_USB_HOST.
- description: EXTCON_CHG_USB_ACA should always appear with EXTCON_USB_HOST.
