We define five sub-devices for which the drivers will be added in subsequent patches. Signed-off-by: Dzmitry Sankouski --- Changes for v9: - use max17042 as fuel gauge chip - initialize max17042 i2c dummy device in mfd device, because bus can be used for reading additional values, not related to fuelgauge, like chip input current, system bus current - fix pmic_rev kernel test robot error Changes for v8: - fix comment style C++ -> C - remove unused pmic_ver Changes for v6: - add PMIC suffix in Kconfig - remove filename from file header - reorder headers alphabetically - move out fg and chg adresses definitions - rename led name and compatible - remove overbracketing - move charger and fuel gauge i2c initialization to their drivers - fix max77705_i2c_driver tabbing - formatting fixes Changes for v5: - license change to 2.0 - use same hardware name in Kconfig and module descriptions 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 | 242 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ include/linux/mfd/max77693-common.h | 5 ++- include/linux/mfd/max77705-private.h | 181 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 443 insertions(+), 1 deletion(-) diff --git a/MAINTAINERS b/MAINTAINERS index c3f66093edd1..b269d0456da3 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -14192,6 +14192,7 @@ 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 @@ -14199,6 +14200,7 @@ 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 diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index ae23b317a64e..17951a9d5a93 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -916,6 +916,18 @@ config MFD_MAX77693 additional drivers must be enabled in order to use the functionality of the device. +config MFD_MAX77705 + tristate "Maxim MAX77705 PMIC Support" + depends on I2C + select MFD_CORE + help + Say yes here to add support for Maxim Integrated MAX77705 PMIC. + 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;
