From 26cc66607189ac544edad04927f506599d990f0f Mon Sep 17 00:00:00 2001 From: Gregory Bean Date: Fri, 10 Sep 2010 15:03:37 -0700 Subject: msm: gpio: Add gpiomux calls to request and free. Add gpiomux get and put calls to msmgpio request and free, in order to allow gpio lines to be properly reference-counted and power-managed.
