2012-04-01regulator: ad5398: show changing current in uAAxel Lin1-2/+2
Integer division may truncate the result. Current code shows changing current is 0mA when selector is 1 ... 8. For example: selector = 1 ad5398_calc_current returns 117, debug message shows 117/1000 = 0mA selector = 2 ad5398_calc_current returns 234, debug message shows 234/1000 = 0mA selector = 3 ad5398_calc_current returns 351, debug message shows 351/1000 = 0mA ............ selector = 8 ad5398_calc_current returns 937, debug message shows 937/1000 = 0mA Show the changing current in uA makes it easier for debugging.

2012-04-01regulator: Refactor to use one da9052_ldo_ops/da9052_dcdc_ops for all LDOs/DCDCsAxel Lin1-186/+44
In current implementation, da9052_ldo_ops and da9052_ldo5_6_ops are very similar, only the set_voltage is slightly different. da9052_buckperi_ops and da9052_dcdc_ops are also similar. This patch adds da9052_regulator_set_voltage for the set_voltage callback used by all LDOs and DCDCs. Rework da9052_get_regulator_voltage_sel and da9052_set_dcdc_voltage to make it possible to be shared by all DCDCs. Rework da9052_list_voltage to make it to be shared by all DCDCs and LDOs. Then we can remove da9052_ldo5_6_ops and da9052_buckperi_ops. We can also remove DA9052_LDO5_6 and DA9052_BUCKPERI macros which is not used now.

2012-04-01regulator: pcf50633: Don't write to reserved bits of AUTO output voltage select registerAxel Lin1-16/+6
The datasheet says 00000000 to 00101110 are reserved, and the min value of the voltage setting is 1.8 V. Thus don't write 0 to AUTO output voltage select register (address 1Ah). Table 50. AUTOOUT - AUTO output voltage select register (address 1Ah) bit description[1] Bit Symbol Access Description 7:0 auto_out R/W VO(prog) = 0.625 + auto_out × 0.025 V eg. 00000000 to 00101110: reserved 00101111: 1.8 V (min) 01010011: 2.7 V 01101010: 3.275 V 01101011: 3.300 V 01101100: 3.325 V 01111111 : 3.800 V (max) ..... ..... 11111110 : 3.800 V 11111111 : 3.800 V This patch also fixes a bug in pcf50633_regulator_list_voltage: In regulator core _regulator_do_set_voltage function: if (rdev->desc->ops->set_voltage) { ret = rdev->desc->ops->set_voltage(rdev, min_uV, max_uV, &selector); if (rdev->desc->ops->list_voltage) selector = rdev->desc->ops->list_voltage(rdev, selector); else selector = -1; The list_voltage call here takes the selector got from set_voltage callback. Thus adding 0x2f to the index in pcf50633_regulator_list_voltage looks wrong to me. e.g. If min_uV < 1.8V, pcf50633_regulator_set_voltage sets 0 to selector. For this case, adding 0x2f to the index in pcf50633_regulator_list_voltage is correct. However, if min_uV == 1.8V, pcf50633_regulator_set_voltage sets 0x2f to selector. Adding 0x2f to the index in pcf50633_regulator_list_voltage in this case is wrong. What this patch does is: The minimal voltage setting for AUTOOUT is 0x2f. Thus for the case min_uV < 1.8, set the voltage setting to 1.8V by writting 0x2f to AUTOOUT register and set selector = 0x2f. So we don't write the rserved range to AUTOOUT register. Which means the possible range of AUTOOUT register value is 0x2f ~ 0xff. We have no problem in regulator_get_voltage. Since we won't write 0~0x2e to AUTOOUT register, we have no problem converting the bits we read to voltage. The equation in auto_voltage_value works fine. For list_voltage, we need to take into account the case selector is 0 ~ 0x2e because the regulator core assumes the selector is starting from 0. This patch returns 0 for the cases selector is 0 ~ 0x2e, which means "this selector code can't be used on this system". The regulator core iterates from 0 to n_voltages to find the small voltage in the specific range. The n_voltages settings for AUTOOUT should be 128 now, including the reserved range of AUTOOUT.
