extcon: axp288: Use vbus-valid instead of -present to determine cable presence

2017-10-08T08:14:16+00:00

[ Upstream commit 5757aca10146061befd168dab37fb0db1ccd8f73 ]

The vbus-present bit in the power status register also gets set to 1
when a usb-host cable (id-pin shorted to ground) is plugged in and a 5v
boost converter is supplying 5v to the otg usb bus.

This causes a "disconnect or unknown or ID event" warning in dmesg as
well as the extcon device to report the last detected charger cable
type as being connected even though none is connected.

This commit switches to checking the vbus-valid bit instead, which is
only 1 when both vbus is present and the vbus-path is enabled in the
vbus-path control register (the vbus-path gets disabled when a usb-host
cable is detected, to avoid the pmic drawing power from the 5v boost
converter).

extcon: max77843: Use correct size for reading the interrupt register

2016-05-04T21:48:54+00:00

commit c4924e92442d7218bd725e47fa3988c73aae84c9 upstream.

The info->status[] array has 3 elements.  We are using size
MAX77843_MUIC_IRQ_NUM (16) instead of MAX77843_MUIC_STATUS_NUM (3) as
intended.

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 */

extcon: gpio: Add the missing supported_cable parameter to devm_extcon_dev_allocate()

2015-09-30T10:22:49+00:00

The commit 2a9de9c0 ("extcon: Use the unique id for external connector instead
of string") defines the unique id of each external connector to identify the
type of external connector instead of string name. So, devm_extcon_dev_allocate()
should include the second parameter (unsigned int *supported_cable). This patch
adds the supported_cable parameter which is passed by platform data.
