extcon: usb-gpio: Remove disable irq operation in system sleep

2022-05-13T08:03:40Z

If disable vbus/id irq, it will lead to wakeup system fail in unisoc platform. In unisoc platform, Irq enable and irq wakeup are the same interrupt line. So remove disable vbus/id irq operation is a way to solve the issue. Signed-off-by: Bruce Chen Acked-by: Roger Quadros Signed-off-by: Chanwoo Choi

extcon: usb-gpio: Use the right includes

2021-10-27T05:13:36Z

The USB GPIO extcon driver does not use any of the legacy includes or but exploits the fact that this brings in . Fix this up by using the right includes. Signed-off-by: Linus Walleij Signed-off-by: Chanwoo Choi

extcon: Replace HTTP links with HTTPS ones

2020-09-24T10:20:48Z

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

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: usb-gpio: Don't miss event during suspend/resume

2017-04-06T01:55:21Z

We must check for ID/VBUS changes during resume irrespective of whether our device wakeup is enabled or not. Without this we seem to be missing ID/VBUS events after system suspend/resume. Signed-off-by: Roger Quadros Signed-off-by: Chanwoo Choi

Revert "extcon: usb-gpio: add support for ACPI gpio interface"

2017-03-27T04:17:41Z

The commit 942c7924a51e introduced a check for ACPI handle for the device that never appears on any ACPI-enabled platform so far. It seems a confusion with extcon-intel-int3496 which does support ACPI-enabled platforms. Revert commit 942c7924a51e to avoid any confusion in the future.

extcon: usb-gpio: Add pinctrl operation during system PM

2017-01-09T01:04:12Z

At some systems, the pinctrl setting will be lost or needs to set as "sleep" state to save power consumption. So, we need to configure pinctrl as "sleep" state when system enters suspend, and as "default" state after system resumes. In this way, the pinctrl value can be recovered as "default" state after resuming. Signed-off-by: Peter Chen Signed-off-by: Chanwoo Choi
