From ba940ed83218f034f728184439c7e87795237752 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 30 Oct 2020 15:34:01 +0100 Subject: power: supply: collie_battery: Convert to GPIO descriptors This converts the Collie battery driver to use GPIO descriptors. We use a mixture of 3 GPIOs defined in the machine and 3 GPIOs requested directly from the ucb1x00 chip.
