2012-12-10regulator: anatop: Use linear_min_sel with linear mappingAxel Lin
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 Lin
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 Lin
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>

2012-11-27regulator: as3711: Fix the logic in as3711_sel_checkAxel Lin
Below equation means the "voltage" is the "smallest" voltage within specific range. ret = DIV_ROUND_UP(min - bottom) / step; voltage = ret * step + bottom; If we do try 1 down when (voltage > max), new voltage is then less than min voltage. Which means the new voltage is not in the requested voltage range. This patch also includes below cleanups: - Use DIV_ROUND_UP - rename variable 'ret' to 'sel' for better readability because as3711_sel_check returns the selector.

2012-11-27regulator: core: Allow specific minimal selector for starting linear mappingAxel Lin
Some drivers (at least 3 drivers) have such variant of linear mapping that the first few selectors are invalid and the reset are linear mapping. Let's support this case in core. This patch adds linear_min_sel in struct regulator_desc, so we can allow specific minimal selector for starting linear mapping. Then extends regulator_[map|list]_voltage_linear() to support this feature. Note that for selectors less than min_linear_index, we need count them to n_voltages so regulator_list_voltage() won't fail while checking the boundary for selector before calling list_voltage callback.
