Subject[PATCH v3 3/9] power: supply: axp20x_usb_power: allow disabling input current limiting
Date
From: Chen-Yu Tsai <wens@csie.org>

The AXP PMICs allow the user to disable current limiting on the VBUS
input. While read-out of this setting was already supported by the
driver, it did not allow the user to configure the PMIC to disable
current limiting.

Add support for this.
