From: Lokesh Vutla Date: Thu, 9 Jun 2016 16:40:21 +0000 (-0700) Subject: ARM: dts: keystone: Header file for pinctrl constants X-Git-Tag: v4.8-rc1~66^2~22^2~1 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=eb53a15b1ab820f51603efd76cdc723fdfafaae0;p=linux.git ARM: dts: keystone: Header file for pinctrl constants The pinctrl IP used in some of the Keystone 2 devices differ vs other TI SoCs. Therefore, create a Keystone specific pinctrl header.
