extcon: max77693: Delete unneeded initialization in max77693_muic_set_path()

2017-11-27T01:23:47+00:00

The variable "ret" will be set to an appropriate value a bit later.
Thus this patch omits the explicit initialization at the beginning.

extcon: Split out extcon header file for consumer and provider device

2017-10-23T05:07:58+00:00

The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect the
   state/properties of external connector. Also, it notifies the
   state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
   from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API for
both provider and consumer device driver. To clarify the meaning of
header file and to remove the wrong use-case on consumer device,
this patch separates into extcon.h and extcon-provider.h.

[Description for include/linux/{extcon.h|extcon-provider.h}]
- extcon.h includes the extcon API and data structure for extcon consumer
  device driver. This header file contains the following APIs:
  : Register/unregister the notifier to catch the change of extcon device
  : Get the extcon device instance
  : Get the extcon device name
  : Get the state of each external connector
  : Get the property value of each external connector
  : Get the property capability of each external connector

- extcon-provider.h includes the extcon API and data structure for extcon
  provider device driver. This header file contains the following APIs:
  : Include 'include/linux/extcon.h'
  : Allocate the memory for extcon device instance
  : Register/unregister extcon device
  : Set the state of each external connector
  : Set the property value of each external connector
  : Set the property capability of each external connector

extcon: Use the extcon_set_state_sync() instead of deprecated functions

2016-09-13T02:26:26+00:00

This patch alters the renamed extcon API to set the state of the external
connectors instead of deprecated extcon_set_cable_state_().

Because the patch[1] modifies the function name to maintain the function
naming pattern.
- extcon_set_cable_state_() -> extcon_set_state_sync()
- extcon_get_cable_state_() -> extcon_get_state()

extcon: Add the EXTCON_CHG_USB_SDP to support SDP charing port

2016-01-25T04:16:53+00:00

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

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     |

--------------------------------------------------

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 */

drivers: max77693: Move state container to common header

2015-07-16T20:39:30+00:00

This prepares for merging some of the drivers between max77693 and
max77843 so the child MFD driver can be attached to any parent MFD main
driver.

Move the state container to common header file. Additionally add
consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).
