5a867cf288 regulator: s2mps11: Optimize the regulator description macro
This patch makes the regulator description macro take minimum and
steps voltage as parameter. In this way many repeated macros can be
removed. Now these macros are repeated only if the the LDO/BUCK ctrl
registers have non-linear positions. The good thing is these ctrl registers
are mostly linear so they are not passed as parameters.

This patch reduces the code size and also allow easy addition of more
s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.

0e4f417857 regulator: s2mpxxx: Move regulator min/step voltages in common place
This is a cleanup patch and moves min/step voltages in a common samsung
header file so that they can be used by other s2mpxxx PMIC drivers. Only
few required macros are added currently and others can be added if needed.

Other bucks have ramp delay enabled always.

However the bit shift for enabling buck6 ramp delay in register is equal

97f53d710b regulator: s2mps11: Add external GPIO control for S2MPS14
Add support for external control over GPIO for LDO10, LDO11 and LDO12
S2MPS14 regulators. External control can be turned on by writing 0x0 to
control register which in case of other regulators is used for disabling
them. These LDO10-LDO12 regulators can be disabled only by I2C GPIO or
PWREN pin so the patch actually allows proper way of disabling them.

Additionally the GPIO control has two benefits:
 - It is faster than toggling it over I2C bus.
 - It allows disabling the regulator during suspend to RAM; The AP will
   enable it during resume.

3e80f95bfc regulator: s2mps11: Copy supported regulators from initconst
Add __initconst to 'regulator_desc' array with supported regulators.
During probe choose how many and which regulators will be supported
according to device ID. Then copy the 'regulator_desc' array to
allocated memory so the regulator core can use it.

Additionally allocate array of of_regulator_match() dynamically (based
on number of regulators) instead of allocation on the stack.

This is needed for supporting different devices in s2mps11
driver and actually prepares the regulator driver for supporting the
S2MPS14 device.

Code for supporting the S2MPS14 device will add its own array of
'regulator_desc' (also marked as __initconst). This way memory footprint
of the driver will be reduced (approximately 'regulators_desc' array for
S2MPS11 occupies 5 kB on 32-bit ARM, for S2MPS14 will occupy 3 kB).

When platform_data is used for regulator (of_node of sec-core MFD device
is NULL) the config.of_node for regulator is not initialized. This NULL
value of config.of_node is later stored during regulator_register().
Thus any call by regulator consumers to of_get_regulator() will fail on
of_parse_phandle() returning NULL.

set the config.of_node to reg_node from platform_data.

232b250475 regulator: s2mps11: Fix wrong setting for config.dev
Currently s2mps11->iodev, s2mps11->dev and config.dev point to NULL.
This patch fixes the settings for config.dev.
Current code does not need the *dev and *iodev of struct s2mps11_info,
so remove them.
