[PATCH v2 0/3] Introduce USB charger support in USB phy
From: Baolin Wang
Date: Mon Jul 03 2017 - 02:08:19 EST
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 USB charger support in USB phy core
for doing this in kernel.
Now introduce one user with wm831x_power to support and test the usb charger.
Changes since v1:
- Fix building errors.
