2012-03-11regulator: Rename s5m8767_convert_voltage to s5m8767_convert_voltage_to_selAxel Lin
This function finds the smallest voltage that falls within the specified range, and then returns the selector. This rename makes the intention more clear. Also remove unneeded local variables min_vol and max_vol in s5m8767_set_voltage and s5m8767_set_voltage_buck.

2012-03-11regulator: tps65910: Sleep off rails when ext sleep configuredLaxman Dewangan
Keep the rails OFF in sleep mode only when the rails are controlled by external sleep control. The devices tps65910 and tps65911, both has the sleep input. The tps65911's sleep input is not same as tps65910's EN3 and hence taking care of SLEEP input as separate external sleep control input.

2012-03-11regulator: Add a pointer to aat2870_data in struct aat2870_regulatorAxel Lin

2012-03-11regulator: Fix n_voltage settings for pcf50633 regulatorAxel Lin
Current code has off-by-one n_voltage settings for AUTO/DOWN*/LDO* regulators. Take ldo1 as example: n_voltage should be (3.6 - 0.9) / 0.1 + 1 = 28 Table 76. LDO1OUT - LDO1 output voltage select register (address 2Dh) bit description[1] Bit Symbol Access Description 4:0 ldo1_out R/W VO(prog) = 0.9 + ldo1_out × 0.1 V (max 3.6V); e.g. 00000 : 0.9 V 00001 : 1.0 V 11000 : 3.3 V 11011 : 3.6 V 11111 : 3.6 V The n_voltage settings for HCLDO and MEMLDO are also wrong. n_voltage for HCLDO and MEMLDO should be (3.6 - 0.9) / 0.1 + 1 = 28 Table 88. HCLDOOUT - HCLDO output voltage select register (addr. 39h) bit description[1] Bit Symbol Access Description 4:0 hcldo_out R/W VO(prog) = 0.9 + hcldo_out × 0.1 V (max 3.6 V); e.g. 00000 : 0.9 V 00001 : 1.0 V 11011 : 3.6 V 11111 : 3.6 V Table 62.
