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.

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>

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.

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.

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.

This patch includes below fixes: 1. The mask variable is not used at all here, remove it. 2. We already have the new_sel and old_sel, simply returns the delay by: DIV_ROUND_UP(desc->step * (new_sel - old_sel), s5m8767->ramp_delay); Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Calling s5m8767_get_reg_id() is exactly the same as calling rdev_get_id(). It is pointless to add s5m8767_get_reg_id() function. Use rdev_get_id() directly and remove s5m8767_get_reg_id() function.

Add support for sleep controls of different regulator through external inputs EN1, EN2 or EN3. Each regulator's output will be active when its external input is high and turns to OFF/Low power mode when its external input is low. The configuration parameters for sleep control is provided through board specific platform data.
