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) This patch adds support for tps65219 mfd device. At this time only the functionalities listed below are made available: - Regulators probe and functionalities - warm and cold reset support - SW shutdown support Signed-off-by: Jerome Neanne --- MAINTAINERS | 1 + drivers/mfd/Kconfig | 15 +++ drivers/mfd/Makefile | 1 + drivers/mfd/tps65219.c | 214 +++++++++++++++++++++++++++++ include/linux/mfd/tps65219.h | 251 +++++++++++++++++++++++++++++++++++ 5 files changed, 482 insertions(+) create mode 100644 drivers/mfd/tps65219.c create mode 100644 include/linux/mfd/tps65219.h diff --git a/MAINTAINERS b/MAINTAINERS index fee3ecc2d6ca..ffd533b8debc 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -14840,6 +14840,7 @@ 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 3b59456f5545..c66e56374a9a 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -1574,6 +1574,21 @@ config MFD_TPS65218 This driver can also be built as a module.

TPS65219 defines two interrupts for the powerbutton one for push and one for release. This driver is very simple in that it maps the push interrupt to a key input and the release interrupt to a key release.
