Subject: [RESEND PATCH v10 0/4] Introduce usb charger framework to deal with the usb gadget power negotation
Date: Tue, 3 May 2016 11:30:13 +0800 [thread overview]
Message-ID: <cover.1462245638.git.baolin.wang@linaro.org> (raw)
Currently the Linux kernel does not provide any standard integration of this
feature that integrates the USB subsystem with the system power regulation
provided by PMICs meaning that either vendors must add this in their kernels
or USB gadget devices based on Linux (such as mobile phones) may not behave
as they should. Thus provide a standard framework for doing this in kernel.
Now introduce one user with wm831x_power to support and test the usb charger,
which is pending testing. Moreover there may be other potential users will use
it in future.
Changes since v9:
- Remove some redundant sysfs attributes.
- Change the SDP charger default current if gadget is SS.
- Remove the 'get_charger_type' callback in gadget->ops.
