From 612ccd90012d7c77bbe67ec65f770b9e82fe4a35 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 21 Apr 2016 14:43:15 +0900 Subject: [PATCH] ARM: uniphier: add sg_set_iectrl_range() For PH1-LD20 or later, per-pin input-enable control is supported, that is, we need to set-up IECTRL registers for a group of pins. This helper function will be useful for a bunch of register settings.
