From 708898fe547bd3d56f0abf7e40f1af91cf4271cf Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Mon, 9 Mar 2015 10:22:41 +0800 Subject: MLK-10176-6 imx: mx7: Modify GPT timer driver for mx7 Modify the GPT common platform driver for mx7 which only use 24Mhz OSC as clock source. Note: at default, the mx7d will use system counter as timer. The GPT is disabled.
