regulator: Use tps65912_set_voltage_sel for both DCDCx and LDOx 2012-03-14T12:37:22+00:00 Axel Lin axel.lin@gmail.com 2012-03-14T02:18:45+00:00 831c986f5dfc9f29f5237697029f7faf24521413 commit 42b5ef "regulator: tps65912: Use simple equations to get register address" uses tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register and tps65912_get_ldo_sel_register.

commit 42b5ef "regulator: tps65912: Use simple equations to get register address"
uses tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register
and tps65912_get_ldo_sel_register.

Now tps65912_set_voltage_dcdc_sel and tps65912_set_voltage_ldo_sel has exactly
the same implementation. Merge them to tps65912_set_voltage_sel function.
