BeagleBone DMTimer using Starterware

Some findings regarding Beaglebone DMTimer using Starterware:

There are 8 Timers available from Sitara Processors:

1. Timer 0 : Fixed clock source which is around 32Khz

2. Timer 2-7 : There are 3 possible clock sources

a. The 24-MHz (typ) system clock (CLK_M_OSC) (Starterware use this by default when we call DMTimerXModuleClkConfig)

b. The PER PLL generated 32.768 KHz clock (CLK_32KHZ)

c. The TCLKIN external timer input clock.

3. Timer 1 clock source configuration not available by default from Starterware, probably because its use by DMTimer1 1ms.

4. Timer 5 & 6 clock source configuration not available by default from Starterware, probably because its use by ethernet device.
