Geert Uytterhoeven 4d9cbff5aa regulator: da9210: Mask all interrupt sources to deassert interrupt line
After boot-up, some events may be set, and cause the da9210 interrupt
line to be asserted. As the da9210 driver doesn't have interrupt support
yet, this causes havoc on systems where the interrupt line is shared
among multiple devices.

This is the case on e.g. r8a7791/koelsch, where the interrupt line is
shared with a da9063 regulator, and the following events are set:

    EVENT_A = 0x00000011 (GPI0 | GPI4)
    EVENT_B = 0x00000002 (NPWRGOOD)

Javier Martinez Canillas 072e78b12b regulator: of: Add regulator desc param to of_get_regulator_init_data()
The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).

Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.

of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.

Guennadi Liakhovetski 937433c250 regulator: da9210: add Device Tree support
This patch adds basic Device Tree support to the da9210 regulator driver -
with no special properties, since also driver's platform data only contains
standard regulator initialisation parameters.
