From 5ea0699a7b452c9e1ecdc81e354fa91dfe8da4f6 Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Thu, 5 Feb 2015 21:23:10 -0800 Subject: Input: bfin_rotary - move pin lists into into platform data Newer Blackfin boards use pinctrl API to manage pins and the legacy peripherial lists are not useful on them. Let's move pin lists into platform data so older boards can still use them and newer boards can use the modern API.
