2012-12-11regulator: core: Fix logic to determinate if regulator can change voltageAxel Lin1-1/+1
Having a linear_min_sel setting means the first linear_min_sel selectors are invalid. We need to subtract linear_min_sel when use n_voltages to determinate if regulator can change voltage. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-12-11regulator: s5m8767: Fix to read the first DVS register.Amit Daniel Kachhap1-3/+3
This patch modifies the DVS register read function to select correct DVS1 register. This change is required because the GPIO select pin is 000 in unintialized state and hence selects the DVS1 register.

2012-12-10regulator: gpio-regulator: gpio_set_value should use cansleepLee Jones1-2/+2
If it's possible for gpio_set_value to sleep, we should be using the *_cansleep call instead. This patch fixes multiple warnings from gpiolib.

2012-12-10regulator: gpio-regulator: Fix logical error in for() loopLee Jones1-1/+1
The cond-statement of this particular for() loop will always be true as long as at least one voltage-shifting GPIO is present. If it wasn't for the break below, we'd be stuck in a forever loop. This patch inserts the correct cond-statement into the statement.

By setting linear_min_sel to anatop_reg->min_bit_val, we can avoid adjust the anatop_reg->min_bit_val offset in [set|get]_voltage_sel. With this chance we can refactor this driver to use regulator_[get|set]_voltage_sel_regmap.

2012-12-10regulator: max1586: Implement get_voltage_sel callbackAxel Lin1-3/+41
This is required since commit f7df20ec32 "regulator: core: Use list_voltage() to read single voltage regulators", otherwise _regulator_get_voltage returns rdev->desc->ops->list_voltage(rdev, 0). The Maxim 1586 controls V3 and V6 voltages, but offers no way of reading back the set up value. Thus this patch caches the setting when setting new voltage.

2012-11-28regulator: pcf50633: Use linear_min_sel and regulator_[map|list]_voltage_linearAxel Lin1-148/+28
This driver can be converted to use linear_min_sel and regulator_[map|list]_voltage_linear. Below shows the equation (from Datasheet) for each LDOs. For AUTOOUT: VO(prog) = 0.625 + auto_out x 0.025 V; e.g. (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) The linear mapping start from 0x2f selector. Thus we convert this equation to: VO(prog) = 1.8 + (selector - linear_min_sel) x 0.025 V (min_uV = 1800000, uV_step = 25000, linear_min_sel = 0x2f) For DOWNxOUT: VO(prog) = 0.625 + downx_out x 0.025 V; e.g. 00000000 : 0.625 V (min) 00010111 : 1.200 V 00101111 : 1.800 V 01011111 : 3.000 V (max) For xLDOOUT: VO(prog) = 0.9 + xldo_out x 0.1 V; e.g. 00000: 0.9 V 00001: 1.0 V 11000 : 3.3 V 11011 : 3.6 V Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
