Subject: [RESEND PATCH v11 0/4] Introduce usb charger framework to deal with the usb gadget power negotation
Date: Mon, 13 Jun 2016 16:46:34 +0800 [thread overview]
Message-ID: <cover.1465807514.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 v10:
- Introduce usb_charger_get_state() function to check charger state.
- Remove the mutex lock in usb_charger_set_cur_limit_by_type() function
in case will be issued in atomic context.
