This patch adds missing registers('BUCK7_SW' & 'LDO29_CTRL'). Since BUCK7 has
1 more register (BUCK7_SW) than others, register offset should
be added one more for which has bigger address than BUCK7 registers.

Buck4 voltage regulator has different minimal voltage value than other
bucks. Commit merging multiple regulator description macros caused to
use linear_min_sel from buck[1235] regulators as value for buck4. This
lead to lower voltage of buck4 than required.
Output of the buck4 is used internally as power source for
LDO{3,4,7,11,19,20,21,23}. On Gear 2 board LDO11 is used as MMC
regulator (V_EMMC_1.8V).

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.

according to device ID. Then copy the 'regulator_desc' array to

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

Currently driver uses local struct s2mps11_info to store ramp rate for bucks
whic its getting through platform data, so instead of using regulator
constraints it should use s2mps11_info to calculate ramp delay.

This patch makes driver to use uV/us as units of ramp_delay. It makes driver
in compliance with regulator framework and make ramp rate precise.
This patch also sets default ramp rate in regulator descriptor which can be
used in case if case ramp rate is not set in regulator constraints.

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.
This patch removes the unneeded include of linux/delay.h in regulator drivers.
