ARM: dts: omap5: board-common: fix wrong SMPS6 (VDD-DDR3) voltage
DDR3L is usually specified as JEDEC standard 1.35V(1.28V~1.45V) & 1.5V(1.425V~1.575V) Therefore setting smps6 regulator to 1.2V is definitively below minimum. It appears that real world chips are more forgiving than data sheets indicate, but let's set the regulator right. Note: a board that uses other voltages (DDR with 1.5V) can overwrite by referencing &smps6_reg. Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
