ARM: ep93xx: clockevent support
I have ported to 3.6-rc1 and slightly modified a previous patch for
clockevent support for the ep93xx.
The porting mainly consists of sched_clock support.
Tested on 9302 based board.

Hi Yan, some comments below.

quoted

+	case CLOCK_EVT_MODE_ONESHOT:
+		tmode |= EP93XX_TIMER123_CONTROL_ENABLE;
+		__raw_writel(tmode, EP93XX_TIMER1_CONTROL);
+		break;
+
+	case CLOCK_EVT_MODE_SHUTDOWN:
+	case CLOCK_EVT_MODE_UNUSED:
+	case CLOCK_EVT_MODE_RESUME:
+		return;

These cases can be removed.

This case is something that is present in most (if not all) other architectures.
I don't mind removing it, but it will have to be replaced with:
default:
     ;

Since GCC produces warnings otherwise.

Other than that I am going to wait a while more for more comments if
somebody has them,
and post a new version with style fixes as well as switch to
drivers/clocksource/mmio.c usage.

Regards,
Yan
