regulator: Add QCOM SPMI regulator driver

2015-06-16T11:14:54+00:00

Add an SPMI regulator driver for Qualcomm's PM8841, PM8941, and
PM8916 PMICs. This driver is based largely on code from
codeaurora.org[1].

regulator: Add input current limit support

2015-06-12T12:18:02+00:00

Some regulators can limit their input current (typically annotated
as ilim). Add an op (set_input_current_limit) and a DT property +
constraint to support this.

regulator: Add soft start support

2015-06-12T12:16:57+00:00

Some regulators support a "soft start" feature where the voltage
ramps up slowly when the regulator is enabled. Add an op
(set_soft_start) and a DT property + constraint to support this.

regulator: Add pull down support

2015-06-12T12:09:43+00:00

Some regulators need to be configured to pull down a resistor
when the regulator is disabled. Add an op (set_pull_down) and a
DT property + constraint to support this.

regulator: Add system_load constraint

2015-06-12T12:05:11+00:00

Some regulators have a fixed load that isn't captured by
consumers that the kernel knows about. Add a constraint to
support this.

regulator: max8973: add support for MAX77621

2015-06-09T17:09:11+00:00

Maxim MAX77621 device is high-efficiency, three-phase,
DC-DC step-down switching regulator delivers peak
output currents up to 16A. This device is extension of
MAX8973 and compatible with the register definition.

The MAX77621 has the SHUTDOWN pin which is EN pin on the
MAX8973. On MAX77621, the SHUTDOWN pin (active low) reset
device register to its POR/OTP value. The voltage output
is enabled when SHUTDONW pin is HIGH and EN bit on VOUT
register is HIGH.

For MAX8973, VOUT is enabled when EN bit or EN pin is high.

Add support of the MAX77621 device on max8973 regulator driver
with following changes:
- Make sure SHUTDOWN pin is set HIGH through GPIO calls if
  GPIO from AP connected to SHUTDOWN pin provided.
- Enable/disable the rail through register access only.

regulator: max8973: add mechanism to enable/disable through GPIO

2015-05-22T12:47:33+00:00

MAX8973 supports the voltage output enable/disable through its EN
pin. This EN pin can be connected through GPIO from host processor.
Add support to provide GPIO number from platform/DT and if it is
valid GPIO then enable external control default.
