2016-11-29mfd: rn5t618: Add Ricoh RC5T619 PMIC supportPierre-Hugues Husson1-0/+1
The Ricoh RN5T567 is from the same family as the Ricoh RN5T618 is, the differences are: + DCDC4/DCDC5 + LDO7-10 + Slightly different output voltage/currents + 32kHz Output + RTC + USB Charger detection Signed-off-by: Pierre-Hugues Husson <phh@phh.me> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-06-29mfd: rn5t618: Register restart handlerStefan Agner1-6/+37
Use the PMIC's repower capability for reboots. Register a restart handler and use a slightly elevated priority of 192 since the PMIC has suprior reset capability (causing a system wide reset).

2016-04-19mfd: rn5t618: Use devm_mfd_add_devices() for mfd_device registrationLaxman Dewangan1-3/+2
Use devm_mfd_add_devices() for MFD devices registration and remove the call of mfd_remove_devices() from .remove callback to remove MFD child-devices. This is done by managed device framework.

2014-09-26mfd: Add Ricoh RN5T618 PMIC core driverBeniamino Galvani1-0/+134
Ricoh RN5T618 is a power management IC which integrates 3 step-down DCDC converters, 7 low-dropout regulators, a Li-ion battery charger, fuel gauge, ADC, GPIOs and a watchdog timer. This commit adds a MFD core driver to support the I2C communication with the device. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
