[PATCH v2 3/9] power: supply: axp20x_usb_power: allow disabling input current limiting
From: Chen-Yu Tsai
Date: Sun Feb 24 2019 - 22:31:39 EST
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.
