This patch enables IRQ handling for MAX8997/8966 chips. Please note that Fuel-Gauge-related IRQs are not implemented in this initial release. The fuel gauge module in MAX8997 is identical to MAX17042, which is already in Linux kernel. In order to use the already-existing MAX17042 driver for fuel gauge module in MAX8997, the main interrupt handler of MAX8997 should relay related interrupts to MAX17042 driver. However, in order to do this, we need to modify MAX17042 driver as well because MAX17042 driver does not have any interrupt handlers for now. We are not going to implement this in this initial release as it is not crucial in basic operations of MAX8997.

* This driver is based on max8998.h
|
|
*
|
|
* MAX8997 has PMIC, MUIC, HAPTIC, RTC, FLASH, and Fuel Gauge devices.
|
|
* Except Fuel Gauge, every device shares the same I2C bus and included in
|
|
* this mfd driver. Although the fuel gauge is included in the chip, it is
|
|
* excluded from the driver because a) it has a different I2C bus from
|
|
* others and b) it can be enabled simply by using MAX17042 driver.
