From e1aaaf3ff311ce03401965a38b33aceac4e51951 Mon Sep 17 00:00:00 2001 From: Pramod Kumar Date: Thu, 19 Nov 2015 09:22:15 +0530 Subject: [PATCH] pinctrl: use ngpios propety from DT Since identical hardware is used in several instances and every instance will have different in-use pins. Hence extracting this number from DT via "ngpios" property.
