The chipsets have same MUIC > component so the extcon, charger and regulators are almost the same. The > max77836 however has also PMIC and Fuel Gauge. > > The MAX77836 uses three I2C slave addresses and has additional interrupts > (related to PMIC and Fuel Gauge). It has also Interrupt Source register, > just like MAX77686 and MAX77693. > > The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the > PMIC block. The PMIC block has different I2C slave address and uses own > regmap so another regmap_irq_chip is needed. > > Since we have two regmap_irq_chip, use shared interrupts on MAX77836. > > This patch adds additional defines and functions to the max14577 MFD core > driver so the driver will handle both chipsets. Also this patch replaces > "0x1 << N" with BIT(N) in defines for register masks. > > Signed-off-by: Krzysztof Kozlowski > Signed-off-by: Chanwoo Choi > Cc: Kyungmin Park > Cc: Marek Szyprowski > --- > drivers/mfd/max14577.c | 217 ++++++++++++++++++++++++++++++++-- > include/linux/mfd/max14577-private.h | 175 +++++++++++++++++++-------- > include/linux/mfd/max14577.h | 7 +- > 3 files changed, 341 insertions(+), 58 deletions(-) Much better, thanks.
