8e8a507c24 regulator: da9052: fix bug in device tree iteration loop
The driver of da9052 is buggy due to the iteration loop of device tree.
This patch fix the loop condition to make the driver work with device tree.

c172708d38 regulator: core: Use a struct to pass in regulator runtime configuration
Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.

The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

0ec446ea9a regulator: Refactor to use one da9052_ldo_ops/da9052_dcdc_ops for all LDOs/DCDCs
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.

9210f05b4e regulator: Fix da9052 ldo regulator names
The regulator name for LDOs are LDO4 ... LDO13 in current implementation.
The correct regulator name for LDOs should be LDO1 ... LDO10.

08bf1c0ae9 regulator: DA9052/53 Regulator support
The Dialog PMIC has below featured regulators:-
DA9052-BC - 4 DVS Buck converters 0.5V - 3.6V upto 1Amp.
DA9053-AA/BX - 4 DVS Buck converters 0.5V - 2.5V upto 3Amp.
DA9052/53 - 10 Programmable LDO's High PSSR, 1% accuracy.

This patch support all the DA9052 and Da9053 regulators. The output voltages are
fully programmable via I2C or SPI interface. The platform data with regulation
constraints is passed down from the board to the regulator.
