Subject: [PATCH v3 3/9] power: supply: axp20x_usb_power: allow disabling input current limiting
Date: Thu, 21 Mar 2019 16:48:44 +0800 [thread overview]
Message-ID: <20190321084850.20769-4-wens@kernel.org> (raw)
In-Reply-To: <20190321084850.20769-1-wens@kernel.org>
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.
