From: Minkyu Kang Date: Wed, 24 Mar 2010 06:31:06 +0000 (+0900) Subject: SAMSUNG: make s5p common gpio functions X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3bb6b037e8557fd3c0f3b3d9840c8b5996651dcb;p=project%2Fbcm63xx%2Fu-boot.git SAMSUNG: make s5p common gpio functions Because of s5pc1xx gpio is same as s5p seires SoC, move gpio functions to drvier/gpio/ and modify structure's name from s5pc1xx_ to s5p_.
