Add the core MFD driver for max77705 PMIC. We define five sub-devices for which the drivers will be added in subsequent patches.
Signed-off-by: Dzmitry Sankouski <[email protected]> --- Changes for V4: - rework driver from scratch - migrate to regmap_add_irq_chip, remove max77705-irq.c, rename max77705-core.c to max77705.c - cleanup headers - remove debugfs code - migrate to use max77693_dev structure - remove max77705.h --- MAINTAINERS | 2 + drivers/mfd/Kconfig | 12 ++ drivers/mfd/Makefile | 2 + drivers/mfd/max77705.c | 248 +++++++++++++++++++++++++++++++++++ include/linux/mfd/max77693-common.h | 6 +- include/linux/mfd/max77705-private.h | 180 +++++++++++++++++++++++++ 6 files changed, 449 insertions(+), 1 deletion(-) diff --git a/MAINTAINERS b/MAINTAINERS index 65cb2511ba22..716e66bb7982 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -14072,6 +14072,7 @@ F: drivers/*/*max77843.c F: drivers/*/max14577*.c F: drivers/*/max77686*.c F: drivers/*/max77693*.c +F: drivers/*/max77705*.c F: drivers/clk/clk-max77686.c F: drivers/extcon/extcon-max14577.c F: drivers/extcon/extcon-max77693.c @@ -14079,6 +14080,7 @@ F: drivers/rtc/rtc-max77686.c F: include/linux/mfd/max14577*.h F: include/linux/mfd/max77686*.h F: include/linux/mfd/max77693*.h +F: include/linux/mfd/max77705*.h MAXIRADIO FM RADIO RECEIVER DRIVER M: Hans Verkuil <[email protected]> diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index f9325bcce1b9..785aac4cb64b 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -904,6 +904,18 @@ config MFD_MAX77693 additional drivers must be enabled in order to use the functionality of the device. +config MFD_MAX77705 + tristate "Maxim Semiconductor MAX77705 PMIC Support" + depends on I2C + select MFD_CORE + help + Say yes here to add support for Maxim Semiconductor MAX77705. + This is a Power Management IC with Charger, safe LDOs, Flash, Haptic + and MUIC controls on chip. + This driver provides common support for accessing the device;
