* regulator: Add Anatop regulator driverYing-Chun Liu (PaulLiu)2012-03-143-0/+250
| | | | | | | | | | | | | Anatop is an integrated regulator inside i.MX6 SoC. There are 3 digital regulators which controls PU, CORE (ARM), and SOC. And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB). This patch adds the Anatop regulator driver.

| | | | | | | | | | | | 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.
