Driver did not provide default value for ramp delay for LDOs which lead
to warning in dmesg, e.g. on Odroid XU4:
[ 1.486076] vdd_ldo9: ramp_delay not set
[ 1.506875] vddq_mmc2: ramp_delay not set
[ 1.523766] vdd_ldo15: ramp_delay not set
[ 1.544702] vdd_sd: ramp_delay not set
The datasheet for all the S2MPS1x family is inconsistent here and does
not specify unambiguously the value of ramp delay for LDO. It mentions
30 mV/us in one timing diagram but then omits it completely in LDO
regulator characteristics table (it is specified for bucks).
However the vendor kernels for Galaxy S5 and Odroid XU3 use values of 12
mV/us or 24 mV/us.
Without the ramp delay value the consumers do not wait for voltage
settle after changing it. Although the proper value of ramp delay for
LDOs is unknown, it seems safer to use at least some value from
reference kernel than to leave it unset.

The driver's init and exit function don't do anything besides registering
and unregistering the platform driver, so the module_platform_driver()
macro could just be used instead of having separate functions.
Currently the macro is not being used because the driver is initialized at
subsys init call level but this isn't necessary since consumer devices are
defined in the DT as dependencies so there's no need for init calls order.

The buck9 regulator of S2MPS11 PMIC had incorrect vsel_mask (0xff
instead of 0x1f) thus reading entire register as buck9's voltage. This
effectively caused regulator core to interpret values as higher voltages
than they were and then to set real voltage much lower than intended.
The buck9 provides power to other regulators, including LDO13
and LDO19 which supply the MMC2 (SD card). On Odroid XU3/XU4 the lower
voltage caused SD card detection errors on Odroid XU3/XU4:
mmc1: card never left busy state
mmc1: error -110 whilst initialising SD card
During driver probe the regulator core was checking whether initial
voltage matches the constraints. With incorrect vsel_mask of 0xff and
default value of 0x50, the core interpreted this as 5 V which is outside
of constraints (3-3.775 V). Then the regulator core was adjusting the
voltage to match the constraints. With incorrect vsel_mask this new
voltage mapped to a vere low voltage in the driver.

Following BUILD_BUG_ON using a variable fails for some of the compilers
and optimization levels (reported for gcc 4.9):
var = ARRAY_SIZE(s2mps15_regulators);
BUILD_BUG_ON(S2MPS_REGULATOR_MAX < var);
Fix this by using ARRAY_SIZE directly.
Additionally add missing BUILD_BUG_ON check for S2MPS15 device (the
check ensures that internal arrays are big enough to hold data for all
of regulators on all devices).

Currently S2MPSXX multifunction device is named as *-pmic,
and these MFDs also supports regulator as a one of its MFD cell which
has the same name, because current name is confusing and we want to
sort it out.
We did discussed different approaches about how the MFD and it
cells need to be named here [1].
Based in the discussion this patch rename MFD regulator name as
*-regulator instead of current *-pmic.
This patch also changes the corresponding entries in the regulator driver
to keep git-bisect happy.

Status of enabling suspend mode for regulator was stored in bitmap-like
long integer.
However since adding support for S2MPU02 the number of regulators
exceeded 32 so on devices with more than 32 regulators (S2MPU02 and
S2MPS13) overflow happens when shifting the bit. This could lead to
enabling suspend mode for completely different regulator than intended
or to switching different regulator to other mode (e.g. from always
enabled to controlled by PWRHOLD pin). Both cases could result in larger
energy usage and issues when suspending to RAM.

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.

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

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).
