Chanwoo writes: Update extcon for 4.11 Detailed description for this pull request: 1. Add the new extcon driver. - Intel INT3496 ACPI USB id detection driver detects whether EXTCON_USB_HOST is attached or detached. (extcon-intel-int3496.c) 2. Add the new type of external connector. - EXTCON_CHG_USB_PD (USB Power Delivery) provides the increased power more than 7.5W to device with larger power demand. 3. Add the description for EXTCON_CHG_USB_(SDP|ACA|SLOW|FAST) - EXTCON_CHG_USB_SDP should always appear together with EXTCON_USB - EXTCON_CHG_USB_ACA would normally appear with EXTCON_USB_HOST. - EXTCON_CHG_USB_SLOW can provide at least 500mA of current at 5V - EXTCON_CHG_USB_FAST can provide at least 1A of current at 5V. 4. Modify the connector name of EXTCON_USB_HOST - "USB_HOST" -> "USB-HOST" 5. Update the extcon core - Move the private extcon structure into driver/extcon directory. The 'struct extcon_dev' should be only handled by extcon core to prevent the direct access and to maintain the integrity of it. - Remove the ambigous operation of extcon_register_notifier() in case of the 'extcon_dev' instance is NULL. The user of extcon_register_notifier() have to specify the correct instance of the provider extcon driver. 6. Update the extcon drivers and fix the minor issues - Update the extcon-axp288 driver to remove the unncessary code. - Add pinctrl operation during suspend mode to extcon-usb-gpio driver. - Clean up the extcon-arizona/adc-jack driver. - Use the dev_dbg() for debug messsage on extcon-palmas driver. - Return the error code on failure of extcon_sync()
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
