extcon: max77843: add device-tree compatible string

2023-10-06T11:39:30+00:00

Add the needed device-tree compatible string to the MAX77843 extcon driver, so it can be automatically loaded when compiled as a kernel module and given device-tree contains separate 'muic' node under the main MAX77843 PMIC node.

extcon: max77843: Replace irqchip mask_invert with unmask_base

2022-12-03T06:03:39+00:00

Remove use of the deprecated mask_invert flag. Inverted mask registers (where a '1' bit enables an IRQ) can be described more directly as an unmask register. Signed-off-by: Aidan MacDonald Reviewed-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi

extcon: max77843: Return error code of extcon_dev_allocate()

2020-09-24T10:20:49+00:00

devm_extcon_dev_allocate() can fail of multiple reasons. The call returns proper error code on failure so pass it instead of fixed ENOMEM. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi

extcon: extcon-max77843: convert to i2c_new_dummy_device

2019-07-24T09:59:05+00:00

Move from i2c_new_dummy() to i2c_new_dummy_device(), so we now get an ERRPTR which we use in error handling. Signed-off-by: Wolfram Sang Signed-off-by: Chanwoo Choi

extcon: max77843: Avoid forcing UART path on drive probe

2018-11-12T00:17:13+00:00

Driver unconditionally forces UART path during probe, probably to ensure that one can get kernel serial log as soon as possible. This approach causes some issues, especially when board is booted with non-UART cable connected to micro-USB port. For example, when USB cable is connected, UART TX/RX lines are unconditionally short-circuited to USB D+/D- lines. This is in turn recognized by a series of serial BREAK signals and some random characters when USB host tries to perform enumeration procedure. To solve the above issue and keep UART console operational as early as possible, set UART path only when USB ID reports UART capable cable.

extcon: max77843: Add support for SmartDock accessory

2017-10-24T00:48:54+00:00

SmartDock uses ADC_RESERVED_ACC_3 (0x10) ADC ID type and provides following features: 1. USB host with embedded USB hub (2-4 ports) for mice, keyboard, etc, 2. MHL for video output, 3. charging. Tested with Unitek Y-2165 MHL+OTG Hub Smart Phone Dock. Signed-off-by: Marek Szyprowski Acked-by: Chanwoo Choi Acked-by: Lee Jones Signed-off-by: Chanwoo Choi

extcon: max77843: Add OTG power control to the MUIC driver

2017-10-24T00:48:40+00:00

Enabling power on VBUS micro-usb pin is required only when passive OTG cable is connected. Initially OTG VBUS power control was planned to be done in charger driver. However such information is not really available from the extcon notifications, so VBUS power control has to be done directly in MUIC driver, which has all information about the attached accessory. For example SmartDock is externally powered accessory, provides OTG (USB HOST) functionality and use VBUS pin for charging a device battery, so the VBUS charging pump should be disabled in such case.

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 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
