regulator: da9063: Add missing initialization of da9063_reg_matches

2013-09-16T23:27:08+00:00

With gcc 4.1.2:

drivers/regulator/da9063-regulator.c: In function ‘da9063_regulator_probe’:
drivers/regulator/da9063-regulator.c:847: warning: ‘da9063_reg_matches’ is used
uninitialized in this function

If the parent device already has platform data, da9063_reg_matches will
not be initialized.

regulator: da9063: Fix PTR_ERR/ERR_PTR mismatch

2013-09-10T17:11:41+00:00

If CONFIG_OF=n:

drivers/regulator/da9063-regulator.c: In function ‘da9063_parse_regulators_dt’:
drivers/regulator/da9063-regulator.c:712: warning: passing argument 1 of ‘PTR_ERR’ makes pointer from integer without a cast
drivers/regulator/da9063-regulator.c:712: warning: return makes pointer from integer without a cast

Use ERR_PTR() to encode an error code in a pointer.
PTR_ERR() is meant to decode an error code from a pointer.

regulator: da9063: Statize da9063_ldo_lim_event

2013-09-01T12:44:18+00:00

da9063_ldo_lim_event() is only referenced in this driver, make it static.

regulator: da9063: Use IS_ERR to check return value of regulator_register()

2013-08-30T14:24:42+00:00

regulator_register() does not return NULL, it returns ERR_PTR on error.

regulator: da9063: Optimize da9063_set_current_limit implementation

2013-08-30T14:24:42+00:00

All the current limit tables have the values in ascend order.
So we can slightly optimize the for loop iteration because the first match
is the minimal value.

regulator: da9063: Add Dialog DA9063 voltage regulators support.

2013-08-29T18:34:59+00:00

The driver adds support for the following DA9063 PMIC regulators:
 - 11x LDOs (named LDO1 - LDO11),
 - 6x buck converters (BCORE1, BCORE2, BPRO, BMEM, BIO, BPERI),

Regulators provide following operations:
 - REGULATOR_CHANGE_STATUS and REGULATOR_CHANGE_VOLTAGE for all regulators,
 - REGULATOR_CHANGE_MODE for LDOs and buck converters, where:
     - LDOs allow REGULATOR_MODE_NORMAL and REGULATOR_MODE_STANDBY,
     - buck converters allow REGULATOR_MODE_FAST, REGULATOR_MODE_NORMAL
       and REGULATOR_MODE_STANDBY,
 - REGULATOR_CHANGE_CURRENT for buck converters (current limits).

The driver generates REGULATOR_EVENT_OVER_CURRENT for LDO3, LDO4, LDO7, LDO8
and LDO11.

Internally, PMIC provides two voltage configurations for normal and suspend
system state for each regulator. The driver switches between those on
suspend/wake-up to provide quick and fluent output voltage change.

This driver requires MFD core driver for operation.
