From 37bed97f00734ce329495823d9682181028b51e4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 14 May 2018 10:06:23 +0200 Subject: regulator: gpio: Get enable GPIO using GPIO descriptor We augment the GPIO regulator to get the *enable* regulator GPIO line (not the other lines) using a descriptor rather than a global number. We then pass this into the regulator core which has been prepared to hande enable descriptors in a separate patch. Switch over the two boardfiles using this facility and clean up so we only pass descriptors around.
