From b930151e5b55a0e62a3aad06876de891ac980471 Mon Sep 17 00:00:00 2001 From: Peter Rosin Date: Wed, 17 Jan 2018 14:34:23 +0100 Subject: [PATCH] pinctrl: sx150x: Add a static gpio/pinctrl pin range mapping Without such a range, gpiolib fails with -EPROBE_DEFER, pending the addition of the range. So, without a range, gpiolib will keep deferring indefinitely.
