From f84a8ecfca9229e9227c6ec84123b114ee634959 Mon Sep 17 00:00:00 2001 From: "Mathieu J. Poirier" Date: Thu, 8 Sep 2011 22:47:40 +0300 Subject: hwspinlock/u8500: add hwspinlock driver Add hwspinlock driver for U8500's Hsem hardware. At this point only HSem's protocol 1 is used (i.e. no interrupts).
