Subject: [PATCH 7/7] omap3: beagle: Use GPTIMERi 1 for clockevents
The current selection of the GPTIMER on was result of
a hardware issue in early versions of the Beagleboards
(Ax and B1 thru B4). [1] [2]
Its been long since the hardware issue has been fixed.
This patch uses GPTIMER 1 for all newer board revisions
incl. Beagleboard XM.
