dfb9b8a4f3 regulator: Sort Kconfig and Makefile entries
Sort Kconfig entries by company name/driver in alphabetical order.
Sort Makefile entries by alphabetical order.

In order to group all the Kconfig entries by company name,
this patch also adds company name to some Kconfig entries.

65364e9ab9 regulator: max8925: fix enabled/disabled judgement mistake
Max8925 ldo status should be determined by two factors:
1. power up/down sequence selection(LDOCTL[4:2]).
2. i2c enable bit(LDOCTL[0]).

Max8925 ldo support two types of power up/down sequence:
1. flexible sequence(LDOCTL[4:2] = 0~6).
2. i2c sequence(LDOCTL[4:2] = 7).

With flexible sequence selected, the ldo is enabled during power up by default.
With i2c sequence selected, the ldo is controlled by the i2c enable bit(LDOCTL[0]).

d9a861cce1 regulator: pass device_node to of_get_regulator_init_data()
It's not always true that the device_node of regulator can be found
at dev->of_node at the time when of_get_regulator_init_data() is being
called, because in some cases the regulator nodes in device tree do
not have 'struct device' behind them until regulator_dev gets created
for it by core function regulator_register().

The patch adds device_node as a new parameter to
of_get_regulator_init_data(), so that caller can pass in the node of
regulator directly.
