extcon: Modify the id and name of external connector

2015-10-15T23:30:09+00:00

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_CHARGE_DOWNSTREAM| EXTCON_CHG_USB_CDP     |
EXTCON_FAST_CHARGER     | EXTCON_CHG_USB_FAST    |
EXTCON_SLOW_CHARGER     | EXTCON_CHG_USB_SLOW    |
--------------------------------------------------
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_SDP	/* Standard Downstream Port */
- EXTCON_CHG_USB_DCP	/* Dedicated Charging Port */
- EXTCON_CHG_USB_CDP	/* Charging Downstream Port */
- EXTCON_CHG_USB_ACA	/* Accessory Charger Adapter */

This patch adds support for the WM8998 and WM1814 codecs.
These use the same IP version as WM5110 but have different

extcon: arizona: Don't disable debounce for inverted jacks

2015-09-22T06:28:00+00:00

Whilst the jack is connected we disable the jack detection debounce to
ensure as quick as possible a detection of jack removal. However, it is
only safe to disable the jack debounce whilst the jack is connected if
using the micd clamp or the jack is not inverted. Otherwise spurious
interrupts might be generated when we re-enable the debounce.

extcon: arizona: Use the micd_clamp for interrupts if it is available

2015-09-22T06:28:00+00:00

Currently we only use the microphone clamp IRQ if GPIO5 is being used as
a second jack detection pin. But we should be using it on any system
where the clamp is available. This patch updates the driver to do so.

extcon: arizona: Additional settings to improve accuracy of HP detect

2015-09-22T06:27:59+00:00

If the TST_CAP_SEL bits aren't set correctly on wm5110/8280 there will
be a 100k load along side the headphones, which will affect the accurary
towards the very top of the detection range. This patch sets those bits.

The switch is typically used in conjunction with the MICDET clamp in

Newer devices give users the option to make the 3/4 pole jack

extcon: arizona: Simplify pdata symantics for micd_dbtime

2015-08-10T02:48:56+00:00

Currently micd_dbtime can be set to 0 for default, 1 for 4 measurements,
or a greater than 16-bit value for 2 measurements. This patch simplifies
the symantics to 2 for 2 measurements, 4 for 4 measurements and any
other value for the default.

I am not super keen on changing the symantics of the pdata at this stage
in the drivers life, but acceptance of the DT binding for this field has
been made conditional on this happening.
