2012-05-18regulator: db8500-prcmu: Separate regulator registration from probeLee Jones1-27/+44
This will provide us with a convenient way to register regulators when booting with Device Tree both enabled & disabled and will save us a great deal of code duplication in time. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-18regulator: ab3100: Use regulator_map_voltage_iterate()Axel Lin1-34/+1
regulator_map_voltage_iterate() is for drivers implementing set_voltage_sel() and list_voltage() to use it as their map_voltage() operation. In this case, regulator_map_voltage_iterate() happen to be doing the same thing as ab3100_get_best_voltage_index() function. So we can use it to replace ab3100_get_best_voltage_index() function.

2012-05-18regulator: tps65217: Convert to set_voltage_sel and map_voltageAxel Lin1-38/+30
Convert tps65217_pmic_ops to use set_voltage_sel and map_voltage. After this convertion, we can also use tps65217_pmic_set_voltage_sel() for set_voltage_sel callback of tps65217_pmic_ldo1_ops. Thus this patch also removes tps65217_pmic_ldo1_set_voltage_sel() function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-18regulator: Enable the ab8500 for Device TreeLee Jones1-0/+54
Here we setup the ab8500 regulator driver for DT. We first do this in the normal way, by providing a match structure during initialisation, but then we provide information so that whilst probing we can use existing data structures to do DT look-ups.

2012-05-18regulator: ab8500: Split up probe() into manageable piecesLee Jones1-63/+87
ab8500's probe() function is becoming quite large, so in the lead up to Device Tree enablement which will fork the thread of execution this patch splits it into 3 main areas; basic error checking will remain in probe(), but regulator register initialisation and regulator registration have been moved to their own functions which will be called in sequence by probe() and the DT equivalent.

Now the implementation of da903x_set_voltage_sel, da9030_set_ldo14_voltage_sel, and da9034_set_ldo12_voltage_sel are exactly the same. da903x_get_voltage_sel, da9030_get_ldo14_voltage_sel and da9034_get_ldo12_voltage_sel are exactly the same.

A lot of regulator hardware maps selectors on to voltages with a simple linear mapping function selector = base + (selector * step size) Provide off the shelf list_voltage() and map_voltage() operations which use new min_uV and uV_step members in the regulator_desc to implement this function.

In order to allow more drivers to factor things out into data allow drivers to provide a mapping function to convert voltages into selectors. This allows any driver to use set_voltage_sel(). The existing mapping based on iterating over list_voltage() is provided as an operation which can be assigned to the new map_voltage() function though for ease of transition it is treated as the default.
