From f70de486b2dd21b60705e57afecdc5f6a79be4e7 Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Mon, 1 Jul 2013 11:24:46 +0800 Subject: Blackfin: bfin_gpio: Use proper mask for comparing pfunc For BF537_FAMILY, when offset != 1, the mask is 1. Thus add proper mask for comparing pfunc with function. Also has small refactor for better readability. In portmux_setup(), it looks odd having "pmux &= ~(3 << 1);" while in current code we do pmux |= (function << offset);.
