ARM: OMAP3: cm-t35: Add regulator for ads7846 touchscreen
ads7846 driver fails to find the regulator supply and as a result the touchscreen is not working. Fix this by adding a regulator supply for the ads7846 driver. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> [tony@atomide.com: updated subject] Signed-off-by: Tony Lindgren <tony@atomide.com>
