regulator: Updates for v3.15
This release has lots and lots of small cleanups and fixes in the regulator subsystem, mainly cleaning up some bad patterns that got duplicated in DT code, but otherwise very little of note outside of the scope of the relevant drivers: - Support for configuration of the initial state for gpio regulators with multi-voltage support. - Support for calling regulator_set_voltage() on fixed regulators. - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung S2MPA01 & S2MPS11/4, some PWM controlled regulators found on some ST boards and TI TPS65218. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJTOVGKAAoJELSic+t+oim9EVMP/ibXoOotc1LWU9ARaZ54ncuu awetV5dugDOQh0uXSJSpo4e6rLV/eZzzKbY29aHN9h76WjM739tOLz2K9cIukZzr VGA1j/uNwa9SOEDfkK++Qj08PXa/4I3ht912S5mL/Afyg8+AIL1UhE0kFjiTH/+r 8axbj0d9f3CZVmOGU4XH3lLBtlWGq++T4cx4sraekra8vNlisBf2cwr1S7j8Apqq K5WsOzlWRFXLxct+UrOrmBLdx1Ln9505wjeL3yrvi2Rnw4TBNDTTWgcSqJ22ecBJ QTr5kbBHuI1qEAcPX4qTzgS0c3TtLQzYjP4K7BZyR5b5EkqpffaA18VVZfo2JQDM Fr+AfxPt2GLMrad1KshHvQFvmlkgKcESGn6vwnLOCw3jXsS/LiaPuiJlmDCCkCI8 tL62dUinm9EUpDEhxnwP/BKikVZCpG/q+TVx0TS1Yfj0p4EBPHrtvkuIMWeMbWCi QLgzdp+iioU5UQ2Fpoblw5z4cQmCryzjOEykEy9Y575SS5/oe7rukVMWt5It4zMV Atgu597v8oZDK6BVZOVq/JuvY9n34mhCBaH3YYRtmbEWXnAe9VjnfJUquWyCvtoz T0FsM7TinOoCgjJr6YbOtK6dksRMnS3AkHS9UEP0MO2jrfKpgJy/IzlSyo6fl7bw OVZc4nMmVX82MxPSJtVj =mrN5 -----END PGP SIGNATURE----- Merge tag 'regulator-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "This release has lots and lots of small cleanups and fixes in the regulator subsystem, mainly cleaning up some bad patterns that got duplicated in DT code, but otherwise very little of note outside of the scope of the relevant drivers: - Support for configuration of the initial state for gpio regulators with multi-voltage support. - Support for calling regulator_set_voltage() on fixed regulators. - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung S2MPA01 & S2MPS11/4, some PWM controlled regulators found on some ST boards and TI TPS65218" * tag 'regulator-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (154 commits) regulator: aat2870: Use regulator_map_voltage_ascend regulator: st-pwm: Convert to get_voltage_sel regulator: Add new driver for ST's PWM controlled voltage regulators regulator: bcm590xx: Remove **rdev from struct bcm590xx_reg regulator: bcm590xx: Make the modalias matches the driver name regulator: s5m8767: Convert to use regulator_[enable|disable|is_enabled]_regmap regulator: db8500-prcmu: Set 1.8V as a fixed voltage for vsmps2 regulator: s2mps11: Add missing of_node_put regulator: s2mps11: Use of_get_child_by_name Documentation: mfd: s2mps11: Document support for S2MPS14 regulator: s2mps11: Add set_suspend_disable for S2MPS14 regulator: s2mps11: Add support for S2MPS14 regulators regulator: max8660: Fix brace alignment regulator: dbx500: use seq_puts() instead of seq_printf() regulator: dbx500-prcmu: Silence checkpatch warnings regulator: anatop: Remove checking control_reg in [set|get]_voltage_sel regulator: max8952: Silence checkpatch warning regulator: max8925: Silence checkpatch warning regulator: max8660: Silence checkpatch warnings regulator: arizona-ldo1: Correct default regulator init_data ...

* Samsung S2MPA01 Voltage and Current Regulator
|
||||
|
||||
The Samsung S2MPA01 is a multi-function device which includes high
|
||||
efficiency buck converters including Dual-Phase buck converter, various LDOs,
|
||||
and an RTC. It is interfaced to the host controller using an I2C interface.
|
||||
Each sub-block is addressed by the host system using different I2C slave
|
||||
addresses.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "samsung,s2mpa01-pmic".
|
||||
- reg: Specifies the I2C slave address of the PMIC block. It should be 0x66.
|
||||
|
||||
Optional properties:
|
||||
- interrupt-parent: Specifies the phandle of the interrupt controller to which
|
||||
the interrupts from s2mpa01 are delivered to.
|
||||
- interrupts: An interrupt specifier for the sole interrupt generated by the
|
||||
device.
|
||||
|
||||
Optional nodes:
|
||||
- regulators: The regulators of s2mpa01 that have to be instantiated should be
|
||||
included in a sub-node named 'regulators'. Regulator nodes and constraints
|
||||
included in this sub-node use the standard regulator bindings which are
|
||||
documented elsewhere.
|
||||
|
||||
Properties for BUCK regulator nodes:
|
||||
- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
|
||||
(default), 25000, or 50000. May be 0 for disabling the ramp delay on
|
||||
BUCK{1,2,3,4}.
|
||||
|
||||
In the absence of the regulator-ramp-delay property, the default ramp
|
||||
delay will be used.
|
||||
|
||||
NOTE: Some BUCKs share the ramp rate setting i.e. same ramp value will be set
|
||||
for a particular group of BUCKs. So provide same regulator-ramp-delay=<value>.
|
||||
|
||||
The following BUCKs share ramp settings:
|
||||
* 1 and 6
|
||||
* 2 and 4
|
||||
* 8, 9, and 10
|
||||
|
||||
The following are the names of the regulators that the s2mpa01 PMIC block
|
||||
supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
|
||||
as per the datasheet of s2mpa01.
|
||||
|
||||
