Hi, > Subject: [PATCH v5 4/6] mfd: tps65219: Add driver for TI TPS65219 PMIC > > The TPS65219 is a power management IC PMIC designed to supply a wide range > of SoCs in both portable and stationary applications. Any SoC can control > TPS65219 over a standard I2C interface. > > It contains the following components: > - Regulators. > - Over Temperature warning and Shut down. > - GPIOs > - Multi Function Pins (MFP) > - power-button > > This patch adds support for tps65219 PMIC. At this time only the > functionalities listed below are made available: > > - Regulators probe and functionalities > - warm and cold reset support > - SW shutdown support > - Regulator warnings via IRQs > - Power-button via IRQ > > Signed-off-by: Jerome Neanne <jneanne@baylibre.com> > Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com> > --- > MAINTAINERS | 1 + > drivers/mfd/Kconfig | 14 ++ > drivers/mfd/Makefile | 1 + > drivers/mfd/tps65219.c | 320 ++++++++++++++++++++++++++++++++ > include/linux/mfd/tps65219.h | 345 +++++++++++++++++++++++++++++++++++ > 5 files changed, 681 insertions(+) > create mode 100644 drivers/mfd/tps65219.c create mode 100644 > include/linux/mfd/tps65219.h > > diff --git a/MAINTAINERS b/MAINTAINERS > index f35b29ffd5fb..960df879c635 100644 > --- a/MAINTAINERS > +++ b/MAINTAINERS > @@ -14926,6 +14926,7 @@ F: drivers/mfd/menelaus.c > F: drivers/mfd/palmas.c > F: drivers/mfd/tps65217.c > F: drivers/mfd/tps65218.c > +F: drivers/mfd/tps65219.c > F: drivers/mfd/tps65910.c > F: drivers/mfd/twl-core.[ch] > F: drivers/mfd/twl4030*.c > diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index > abb58ab1a1a4..1a846c7dd0c2 100644 > --- a/drivers/mfd/Kconfig > +++ b/drivers/mfd/Kconfig > @@ -1576,6 +1576,20 @@ config MFD_TPS65218 > This driver can also be built as a module.
