	patches, cw00.choi, myungjoo.ham

This patch-set modify the id and name of external connector with the additional
prefix to clarify both attribute and meaning of external connector as following:
- EXTCON_CHG_* mean the charger connector.
- EXTCON_JACK_* mean the jack connector.
- EXTCON_DISP_* mean the display port connector.
And when altering the name of USB charger connector, this patch refer the
standard USB charger name about SDP, CDP, DCP and ACA.

Changes from v1:
(https://lkml.org/lkml/2015/10/3/304)
- Add acked tag by Charles Keepax for arizona changes
- Modify the name of USB charger connector as following:
 : EXTCON_CHG_USB_FAST -> EXTCON_CHG_USB_DCP_FAST
 : EXTCON_CHG_USB_SLOW -> EXTCON_CHG_USB_DCP_SLOW
- Add the missing EXTCON_CHG_USB_ACA charger connector
- Add one more patch to support the EXTCON_CHG_USB when SDP port is connected or not

This patch modifies the id and name of external connector with the additional
prefix to clarify both attribute and meaning of external connector as following:
- EXTCON_CHG_* mean the charger connector.
- EXTCON_JACK_* mean the jack connector.
- EXTCON_DISP_* mean the display port connector.

Following table show the new name of external connector with old name:
--------------------------------------------------
Old extcon name         | New extcon name        |
--------------------------------------------------
EXTCON_TA               | EXTCON_CHG_USB_DCP     |
EXTCON_FAST_CHARGER     | EXTCON_CHG_USB_DCP_FAST|
EXTCON_SLOW_CHARGER     | EXTCON_CHG_USB_DCP_SLOW|
EXTCON_CHARGE_DOWNSTREAM| EXTCON_CHG_USB_CDP     |
--------------------------------------------------
EXTCON_MICROPHONE       | EXTCON_JACK_MICROPHONE |
EXTCON_HEADPHONE        | EXTCON_JACK_HEADPHONE  |
EXTCON_LINE_IN          | EXTCON_JACK_LINE_IN    |
EXTCON_LINE_OUT         | EXTCON_JACK_LINE_OUT   |
EXTCON_VIDEO_IN         | EXTCON_JACK_VIDEO_IN   |
EXTCON_VIDEO_OUT        | EXTCON_JACK_VIDEO_OUT  |
EXTCON_SPDIF_IN         | EXTCON_JACK_SPDIF_IN   |
EXTCON_SPDIF_OUT        | EXTCON_JACK_SPDIF_OUT  |
--------------------------------------------------
EXTCON_HMDI             | EXTCON_DISP_HDMI       |
EXTCON_MHL              | EXTCON_DISP_MHL        |
EXTCON_DVI              | EXTCON_DISP_DVI        |
EXTCON_VGA              | EXTCON_DISP_VGA        |
--------------------------------------------------

And, when altering the name of USB charger connector, EXTCON refers to the
"Battery Charging v1.2 Spec and Adopters Agreement"[1] to use the standard name of USB
charging port as following. Following name of USB charging port are already used
in power_supply subsystem. We chan check it on patch[2].
- EXTCON_CHG_USB	/* Standard Downstream Port */
- EXTCON_CHG_USB_DCP	/* Dedicated Charging Port */
- EXTCON_CHG_USB_CDP	/* Charging Downstream Port */
- EXTCON_CHG_USB_ACA	/* Accessory Charger Adapter */

The SDP (Standard Downstream Port) is one of various USB Charging ports. The SDP
supports both the data transmission and the charging through USB connector at
the same time. So, the EXTCON framework defines two connector type for USB SDP
connector as following:
- EXTCON_USB means the USB cable for data transmission.
- EXTCON_CHG_USB means the USB charger cable for battery charging.

This patch add the support of EXTCON_CHG_USB when USB SDP is attached or
detached.

Hi Choi,


> Subject: [PATCH 1/2] extcon: Modify the id and name of external connector
> 
> This patch modifies the id and name of external connector with the additional
> prefix to clarify both attribute and meaning of external connector as following:
> - EXTCON_CHG_* mean the charger connector.
> - EXTCON_JACK_* mean the jack connector.
> - EXTCON_DISP_* mean the display port connector.
> 
> Following table show the new name of external connector with old name:

It is possible. But, the unique id of external connector will be used on device tree file
as following patch[1]. Following patch[1] defines the include/dt-bindings/extcon/extcon.h
which is include in *.dts file. In *.dts file, we can not use the 'enum'.
[1] https://lkml.org/lkml/2015/10/5/38
So, I use the "#define" keyword instead of enum.

I used the 'enum' on first patch to define the unique id
but I altered it by using '#define' instead of 'enum' on following patch[2].
[2] commit 73b6ecdb93e8e ("extcon: Redefine the unique id of supported external connectors without 'enum extcon' type")

As you knew, SDP support both data transmission and charging
through one port at the same time. Also, On patch1 of this patch-set,
I add the prefix to clarify both attribute and meaning of external connector as following:
- EXTCON_CHG_* mean the charger connector.

So, there are three possible naming approach for USB SDP.

Approach 1.
- EXTCON_USB		/* SDP for both data transmission and charging */

Approach 2.
- EXTCON_USB		/* SDP for data transmission */
- EXTCON_CHG_USB	/* SDP for charging */

Approach 3.
- EXTCON_CHG_USB	/* SDP for both data transmission and charging */

It is not fixed about name. I want to discuss what is proper name for USB SDP.

Thanks,
Chanwoo Choi

This only adds confusion. There is only one cable that will always do both jobs
so no point in using 2 names for it.

I do not have any preference over 1 or 3.

I'll drop this patch. Also, I'll use only EXTCON_USB and delete the EXTCON_CHG_USB
from patch1 on next version.
