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

2017-10-23T05:07:58Z

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 Signed-off-by: Chanwoo Choi Acked-by: Sebastian Reichel Acked-by: Chen-Yu Tsai Acked-by: Charles Keepax Acked-by: Lee Jones Acked-by: Felipe Balbi Acked-by: Yoshihiro Shimoda Acked-by: Kishon Vijay Abraham I

extcon: Use the extcon_set_state_sync() instead of deprecated functions

2016-09-13T02:26:26Z

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() [1] https://lkml.org/lkml/2016/8/4/729 - extcon: Rename the extcon_set/get_state() to maintain the function naming pattern Signed-off-by: Chanwoo Choi Acked-by: Charles Keepax Acked-by: Roger Quadros

extcon: gpio: Remove the usage of extcon_set_state()

2016-09-10T11:18:47Z

This patch removes the usage of extcon_set_state() because it uses the bit masking to change the state of external connectors. The extcon framework should handle the state by extcon_set_cable_state_() with extcon id. Signed-off-by: Chanwoo Choi

extcon: gpio: Fix typo in comment

2016-01-25T04:16:53Z

This patch fixes the typo in comment of extcon-gpio.c driver. - 'interrput' -> 'interrupt' Signed-off-by: Moritz Fischer Signed-off-by: Chanwoo Choi

extcon: gpio: Use descriptor-based GPIO interface instead of legacy gpio_* API

2015-09-30T10:22:50Z

This patch uses the descriptor-based GPIO interface (gpiod_* API) instead of legacy gpio_* API and add the internal gpio_extcon_init() to handle all gpio-related tasks. Signed-off-by: Chanwoo Choi

extcon: gpio: Fix minor coding style and remove the unused fields.

2015-09-30T10:22:50Z

This patch fixes the minor coding style about indentation and removes the unused fields from struct gpio_extcon_platform_data. Signed-off-by: Chanwoo Choi

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

2015-09-30T10:22:49Z

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.

extcon: gpio: Remove duplicate data from struct gpio_extcon_data

2015-09-30T10:22:49Z

There are duplicate data between struct gpio_extcon_data and struct gpio_extcon_platform_data. This patch removes them from struct gpio_extcon_data. Instead, this patch add pdata field to struct gpio_extcon_data. Signed-off-by: Chanwoo Choi
