* regulator: Fix s5m8767_set_voltage_time_sel calculation valueSangbeom Kim2012-03-111-1/+1
| | | | | | | | In the s5m8767_set_voltage_time_sel function, divisor unit is wrong. ramp_delay is usec unit. So 1000 should be multiplied. Signed-off-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* regulator: tps65910: Sleep off rails when ext sleep configuredLaxman Dewangan2012-03-111-4/+13
| | | | | | | | | | | 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.

* regulator: Add a pointer to aat2870_data in struct aat2870_regulatorAxel Lin2012-03-111-7/+7
| | | | | | | | | | | The reason we add *pdev in struct aat2870_regulator is to use it to get a pointer to struct aat2870_data. Save a pointer to struct aat2870_data instead of pdev in struct aat2870_regulator, this change makes the intention more clear.
